The latest edition of "Wildlife Matters" published by the Australian Wildlife Conservancy claims that Australia's 15 million feral cats (conservative estimate) kill a minimum of 75 million native animals EVERY NIGHT. That would include a lot of birds. If anyone is interested, they can donate to AWC's strategy to reduce the impact of feral cats. AWC's website is http://www.australianwildlife.org.
Thanks so much for putting up the link, our wildlife deserves all the help it can get. It's not only cats though, I picked up a Bluetongue Lizard yesterday and took him to the vet, he had been bitten by a dog.

Yes, Araminta, that guy needs to be kept inside constantly with a bell around his neck. Hopefully, he'll be the last one his owner ever has.
Interesting article...
"The ACT government has put an end to the cat curfew in some Canberra suburbs - and replaced it with cat containment.
Minister for Territory and Municipal Services Shane Rattenbury said the change “aims to enhance community understanding and awareness of the objectives of the law and to more clearly communicate the obligation of those living within cat containment areas”.
Mr Rattenbury introduced a bill on Wednesday changing the word "curfew" to "cat containment" in the Domestic Animals Act 2000.
“While cats play a valuable role as companion animals, roaming cats can pose a serious threat to native flora and fauna in the area,” he said."

Guys please don't blame animals, they only act on their natural instincts, but please do blame people for neglecting the animal's ( pet ) needs, animals aren't aware of the damage they cause to an ecosystem, but people with their higher intellect are aware of their every action but decide not to care for the environment because it isn't important to them. We need to prohibit the ownership of predatory and invasive exotic animals and if we don't we only have ourselves to blame.
For Australian birds, natives=life, exotics=death, so do them a favour and go plant some natives and save their lives.
I understand, I hope, what you're saying, doublebar. But what do you suggest we do with feral & wandering cats in the meantime?
Ah doulblebar, some of my neighbours must be of some kind of lower intellect then, or still waiting to be enlightened? For some of those not even huge fines work....., I put up signs around my fences, but.... only my trap does the trick !

What needs to be done is to stop the sale of cats/kittens at the local pet store and weekend markets and cats should only be sold through approved breeders who would only sell cats that are desexed and registered, the registration info would be in the form of a microchip under the skin. The registration would enable the authorities to find the owner and fine them for letting the cat roam outside a designated area eg. the owner's backyard. The owner would also be required by law to report the cat's condition to the nearest vetenary every six months. No one would be allowed to keep more than 2 cats. For the feral cats any quick and humane method of eradication would be best unless they can be domesticated and adopted out to responsible owners. Cats are beautiful animals and like all animals need to be treated with respect, it's people that are the cause of the feral animal problem not the animals.
For Australian birds, natives=life, exotics=death, so do them a favour and go plant some natives and save their lives.
Hi doublebar. Your suggestions are useful steps in the direction of protecting Australian wildlife. But I note that they don't include a requirement that all cats be kept confined to a cat race or inside a house although you do mention "designated" areas. There is still sufficient latitude allowed cats in your proposals to give cats priority over wildlife. I really don't think we can afford to allow this any longer such is the parlous state of our wildlife.
In addition to your proposals I would add the questions: Should cat owners be required by law to immediately report when their cats go missing? Should owners be heavily fined if they don't report their pets' new found freedoms to roam & destroy wildlife?
Personally, I don't think it's a matter of treating cats with respect or disrespect. It's a matter of chosing between priorities: cats or Australian wildlife. No doubt the strength of the cat lobby, although seemingly waning, will ensure that the former take precedence over the latter for the foreseeable future. Unfortunately, by the time we get around to reversing these priorities there will be little wildlife left to protect. As with global warming, it was ever thus.
Cats are beautiful animals indeed but they have no place in Australia, in my view. No doubt others will disagree. But you're right in sheeting home responsibility for feral cats to humans, (cat owners in particular, I suggest). In fact, I'd go so far as to say that the only responsible cat owner is a non-cat owner if that's not too oxymoronic.

The only place for a cat in Australia is a cat run and indoors. If it is outdoors, it becomes feral!
Well, Peter, what can I say!?
Just a reminder everyone - I understand entirely that cats are an emotive subject and that we have people here on both sides of the fence but there are to be no posting promoting cruelty to them or any other animals as per the forum rules.
My neigbours cat kills heaps of birds, I was really upset when I found what was left of one of the Magpies I had tamed But realisticly animals will do what they do, its nature and nature is tough...
Tonight I was at my stepsons home for a mothers day tea, as we were clearing things away our granddaughter Chloe came running up to me very upset cupped in her hands was a dead New-holland Honey-eater ,she had just taken it from the cat ,it was still warm, I looked at the cat and then turned to him and said where's the refletive coller I bought for you rotten cat !
His responce , it wouldn't do any good the cat kills birds at night !
I said what the ------ is your cat doing outside at night ,then I got "don't start" the cat killed a bird so what ,I went right off, after all my harping and talking and even buying a collar and putting it on myself I still can't get through to him ! (I don't think I'll be invited back anytime soon)
I don't hate cats, we have one he is 14 years old and has spent his whole life inside !
Its not the cats fault I know ,there killers they can't control there instinct to hunt but that doesn't mean we should let them we have to control their behavior by whatever means avalable there are to many people either on the cats side or with their heads in the sand hopeing it will all just go away ,I better stop now I'm still a bit wound up !
Please answer one question, why edit a truth? It is not cruel to terminate a feral animal, it is what people cannot face that is cruel. When a person eats the steak or chop that they have purchased from the butcher or supermarket, do they wonder about the way the beast has been treated on the way to the saleyards? Do they know about the shockers they use to get them on the trucks? Do they know the fate of the Mickeys that don't get to the trucks because they have been wild one year to many? Then do they know the broken bones from transport? Do they know about the fact that are not fed or watered before transport because the truckers don't want to clean the trucks?
And you go ahead an edit a comment about 29 grains of lead travelling at 1300 feet per second! Unbelievable and start to grow up. As soon as I get a response from this I will be sure to delete myself from this forum. Better still, I suggest you do it for me. I firmly believe you were wrong to edit my comments and you should be ashamed to call yourself a native bird lover!
It is not cruel to shoot a cat in the head, it is cruel to allow a cat to toy with a live animal for hours. It is cruel to have a cat roam free to wreak havoc upon our wildlife. It is cruel that people cannot be pragmatic and undertand the devastation one cat can cause in a single night.
I am done and disappointed as I thought this was a good forum from what I had read as a visitor. Maybe living in the country and realising that city people cannot handle reality is a good indication of why my comments were edited!
Peter I agree, humanely euthanising a feral animal is not cruel at all and feral cats are undoubtedly a huge problem facing our wildlife that we need to somehow find a solution for (along with other feral species). When including domestic along with feral cats then the situation gets more complicated of course - the human factor, whilst frustrating at times, is a significant one.
The section of the post that I edited crossed the line. As I said earlier - the issue of cats is a difficult one and a very passionate subject for many. This is not about my personal views, but the forum rules.
I am going to keep this thread open but there are to be no more discussions on my decision.
I think there are a lot of people who take your stance Peter, so there's no need to penalise yourself by leaving the forum. Your participation is valuable like everyone else's. And as you say, its a good forum. Holly's just doing her job as all responsible administrators do. Without an administrator forums can gradually descend and degrade to a point where they are of no benefit to anyone. I think its really just a problem of detail, or too much of it.
At his request, and after his statements against the administration of the site Peter has been blocked from the forum.
Tut tut. I'd have thought this forum and its ideals need all the participants and supporters it can get. I'm sad to see this outcome, while realising of course that there are rules to abide by.
Hey Shorty ... I was really surprised to see you post this and to make the comments you did ..... you are usually of a more conservative nature and I always enjoy your posts.
I really wish that people , especially longer term members who know what is going to happen, just lay off this issue. It has always ended up in problems such as those in this thread.... such an emotive issue and this "feral"in the picture is not the same animal as the one who sits indoors all day but is allowed out in his garden.
The millions of ferals are in an entirely different category in my opinion and obviously are breeding amongst themselves at a terrible rate. As has been said...they and mankind can both be feral when it comes to the environment, we all know that. Attacking people with domestic cats just opens the can of worms and invites the kind of comments every time that are usually not welcome here. It is one thing to make people aware of the issue by posting links to be read etc, but another entirely to get into a discussion about ways to exterminate and so on. What needs to be done is more education with young people and penalties for indiscriminate breeding of domestic cats... if they were all sterilised before becoming a pet that would be half the problem solved at least. But we cannot enforce sterilisation on the ferals in Kakadu or in National Parks .... curfews for the cities or control pens are obviously only a small part of the problem that has become out of control. That is my opinion anyway and I do not want to enter into a Cat hating debate..... I mean...after reading that Sugar Gliders are the biggest predator of some small birds ...should we start hating them too now?
Just suggesting that maybe a bit of common sense would avoid unpleasant situations for Holly that she shouldnt have to put up with especially from people who have been here a long time .

+1 for Birdie's comments. Maybe one of the cats/ferals threads could be stickied and locked so that the topic stays dormant?
I respect Birdie's and Lachlan's views but I for one don't intend to lay off or put to sleep an issue that is MOST relevant to a bird forum like this. Just because something is unsavoury to some, does it mean we shouldn't talk about it? Does it mean we shouldn't have different views? Isn't that what a forum is? People on this forum know my view that cats have no redeeming features at all; they killl (and torture) native birds and animals in their millions, they spread disease (toxoplasmosis) to humans and they adapt quickly to a feral state when abandoned by their non-caring bogan owners after passing their cute kitten stage.
On the subject of cruelty, yes I despise cruelty to animals. Cruelty to me is locking a bird or animal in a small cage for its lifetime (go to south east asia or China to see state of the art cruelty), or what a cat does when it toys with its live prey. It is not the destruction of vermin for the purpose of saving countless native birds and animals, or native fauna. It doesn't happen in the cities much, and it may horrify some, but it is a fact of life we can't, and shouldn't, ignore just for the sake of nicety. I think this was all that the now-exiled Peter was trying to point out.
Let's all grow up a little and stop turning a blind eye to things that stare us in the face. This is a good forum and I am always ready to read about how others think. I don't expect to silence them just because I don't agree with their views.
You've had your say an there is no need to be personal about "let's all grow up a little" .... I for one am a grown up and do not need you telling me to do that. I am stating an obvious fact .... it always ends in someone being blocked or deleted and it never gets us anywhere. We are grown up and we are aware that there is a problem with feral cats . As for Peter ... he exiled himself by attacking the admin in an uncalled for manner. You would know full well that so many people have pets that they love and that it is an emotive issue ..... but you don't see us on here telling you how lovely they are or bothering you with any of that. We respect the forum rules and try to avoid the subject simply because it gets us nowhere on a forum such as this to allow the issue to degenerate. I respect all of your views on saving the environment ... I think we all do
Sunshine Coast Queensland
Just because an animal is "vermin" doesn't make cruelty to it any more justified. You're right, Night Parrot- the damage feral species are doing to the environment should not be ignored, but there has to be better way to manage the situation than ruthless extermination.

That dog deliberately stalked and went for that little boy.... I guess we should ban dogs too now? Having said that I hope it gets put down as it obviously has a very unreliable temperament. And once again ... it is not the breed but the owners that need to be responsible ...
Shorty havent watched your videos yet ... I gather you are tongue in cheek though? There cant be too many cats attacking humans in the world that result in severe damage surely ?

You make a good point about dogs Birdie, around my area dogs are more of a problem than cats. Most cats get desexed(which tends to stop them roaming), we get the occasional feral cat, but dogs love to roam around the countryside. People are reluctant to keep their dogs restrained all day so they are often loose, they chase wildlife and can be dangerous to people and stock. Lifestock also cause major environmental damage and are a big cause of habitat loss. It is easy to blame things on the ferals, but the real problems are much bigger than that.
Yes Greg in the reserves and walkways I use the problem is usually dogs rather than the moggies that are kept inside...not saying that there aren't cats that are roaming too of course. I regularly see people who think it is good sport to let their stupid dogs chase birds on the beach ,,, in one case a beach where theh council has designated it as a dog beach sure, and I love to use it, but they also know that the wading birds use it to rest and recover at different times of the year . Breaks your heart to see the poor things having to fly every time a stupid dog owner lets their dog have free rein. It is possible to walk a trained dog off leash and have him not pay attention to birds... I do it all the time ... The poor old Bush Turkeys are regularly seen minus a leg or something as they seem to be seen as fair game by such owners .
Regarding cats... I think the first step for suburban welfare at least is to ban the indiscriminate sale of kittens by idiots who let their cats breed for no reason and get them totally out of Pet Shops. All cats should be sterilised as soon as they are old enough and it should be complusory . I know of people who have let their kids breed their cat with the local tom so that they can make some pocket money.... these are intelligent and very nice people ... however the cats were sold unchecked, unvaccinated and unsterilised .... therefore allowing the same ridiculous scenario to persist. I tried everything to teach the kids that it was wrong but because the parents were not engaged in the issue it did no good sadly it comes down to people's priorities , and for many the environment and "a few birdies or possums etc" come very low on their list. These same people have health as a major priority and are so strict on healthy eating etc . Unfortunately the "it's just a bird " mentality is still very much alive and well . If they can administer drops to the skin that stops a fleas breeding cycle ..... I wonder that there isnt something that can do the same to cats? Just a thought as it is the breeding cycle that is the crux of the problem
Sunshine Coast Queensland
Strange how people who have health as a priority keep a cat.
Those sterilising "drops to the skin" could be made for global human use as well.
Night Parrot ... I have had cats all my life and they have never given me anything but pleasure.... any ill health has certainly not been due to them. The cats were only a part of the health issue believe me, same kids were breeding and selling birds (parrots included) and sleeping with them in their rooms ... that was something I just couldn't fathom at all. The dust , mites, droppings, feather powder, dander whatever was disgusting but they were all over the place... Thankfully that phase in their lives is all gone now but it disturbed me on all accounts believe me ... and the many kittens are out there and have probably multiplied ten fold since then

Wikipedia says 350,000 people are infected by toxoplasmosis every year. It also says people infected can have no illness initially.
Correction. 350,000 people in Britain.
Ok, I have been thinking about how to respond to this discussion over the last few days without offending anyone or creating a rift between us.
Firstly I would like to say that I do not condone nor tolerate cruelty to ANY animal.
Ever since I was a small child I have spent a lot of time in the bush ( a lot more than most )and have seen the damage feral animals do. I have seen first hand the attacking off feral cats and dogs on our native wildlife and that is why I am passionate on the subject.
We could just bury our heads in the sand and hope the problem goes away or we could discuss the issue in a calm and thoughtful manner and hopefully come up with a solution to this very large and destructive problem.
I feel the problems we have had in this post is that people are turned off and perhaps shocked about the call for guns as a solution to the problem, so I would like to explain a few things based on fact and not emotion.
There are currently 4 main methods of control that are used to on feral animals.
Now I know that guns are a contentious issue, mostly due to idiots that shoot endangered ducks. In my opinion a high powered rifle in the hands of an ethical marksman is the most humane way of controlling feral animals.
I will use the yearly kangaroo cull in Canberra as one example for my reasons. I do not agree with the cull but I do agree with the method used.
They employ 2 ex Olympic marksmen, they use very accurate and high powered rifles , they cancel the shoot if there is any wind and will not pull the trigger on a moving animal or if it is not in clear sight and it has to be at the correct distance to ensure accuracy. The main shooter determines if the shot is on, and only if he is confident does he take the shot. Now this is where the second shooter comes in. Once the main shooter takes his shot the second shooter keeps an eye on the animal through his scope and if something has gone wrong and the animal has not had an immediate death he immediately fires to minimize suffering to the animal.
The next method is 1080 poison, again this is performed by an expert in toxicology who places the correct amount of poison to the bait for the intended animal to ensure a quick death but it can take a minute or two for this to occur. They use this for cats, dogs, pigs and rabbits to name a few.
One of the problems with this method is there are what they call an acceptable level of by-kill of native animals that eat the bait. Another problem is when a bait is intended for say a rabbit, when an animal eats the infected rabbit it suffers a painful death as the toxins are not strong enough for an immediate death. I have seen this on a couple of occasions with the most recent less than 2 weeks ago at the wetlands, a fox had eaten infected rabbits and I won’t go in to detail but I think most of you would have been very disturbed by this sight. My problem was not just seeing this disturbing sight but the fact that Currawongs and Ravens were congregating to eat the fox and would then be infected as well. Lucky for me the ranger was around at the time and I alerted him off the situation and he put the poor animal out of his pain and removed the body so no other animal came to the same demise.
The next method but only used on rabbits is the Calicivrus, this takes up to 2 days for the demise to take effect.
Again only used on rabbits is Myxomatosis, this is by far the most inhumane method, it can take up to 2 weeks to end the suffering of the rabbit.
I do realize that this may seem confronting to some but I would like to think that after reading this you may be a little more educated on the problems we face and the programs we have going on that are not classed as humane in my opinion.
In conclusion, the feral animal problem is very real and a very big problem. Something needs to be done and now.
I don’t say that guns are the best solution but with our current resources is the best solution to contain the problem until a better solution can be found.
Stricter rules on keeping potential feral animals are needed to minimize the problem.
I know some will not agree with me but I hope we can have a healthy and civil debate on the subject without personal attacks.

Good post Shorty. It certainly is an emotive subject and I agree with you that it isn't one that we should ignore. I believe that the cat containment plan in Canberra is a major step in the right direction.
I once witnessed the full effects of Myxomatosis on a rabbit population in Scotland as a teenager and I can tell you it was absolutely horrific and still haunts me to this day. At the time there was literally hundreds of rabbits with huge sores on their bodies with eyes cloudy and half closed. You could walk right up to the rabbits and they were almost unaware of you. For anyone who isn't aware of this disease just type Myxomatosis into google images.
A terrible disease that was introduced by man to reduce rabbit numbers that still effects rabbit populations to this day. Most infected rabbits die of internal bleeding and or seizures over about a10 day period and very contagious among rabbits. It's a very slow painful death. There are vaccines in other countries, but the strains of Myxo can be different therefore a vaccine that works in one area may not in another.
Samford Valley Qld.
Thanks for a very informative post Shorty ... and knowing you are a ranger now and spend lots of informed time in the bush makes me understand why you posted the feral pic. I still stand by my views that as you said we can start with stricter rules on keeping animals with the potential to go feral .... sterilisation should be primary I believe. As for the guns..... of course this is the kindest way to despatch ferals as long as it is done in the controlled way that you describe. Some of these feral cats I believe can getup to 15KG in weight out in theh bush ... and that is no pet pussy by anyones standards. But that doesn't mean it is fair game to shoot the next door neighbour's pet cat on sight. As for 1080 ..... gosh I remember my friends losing their beautiful German SHort Haired pointer while camping in Dwellingup south of Perth .... sadly she took a bait while they were bush walking. He was an experienced "bushie" and had a huge respect for the environment , but that sight brought him and his wife to their knees that day . As you say ..the carcasses then infect the birds etc that feed on carion . what to do? I certainly do not know.
As for Cats spreading and carrying Toxoplasmosis .... yes that is a fact..... also a fact is that Chickens ,pigs and cattle can carry Salmonella ...people contract that regularly too, but we don't look to kill all the chooks etc in the world. Bats carry the Lissavirus which is a regular problem here in Queensland, horses can carry Hendra which has resulted in several deaths over here too. I myself have had Giardia when living in the Kimberley .... that can be found in birds , cattle and a number of other animals .Good hygiene as in all diseases goes most of the way to prevention.
Clearly , Night Parrot, you detest cats and everything about them ... they are never going away ... so a more balanced approach would be helpful in a forum such as this if we want to have informative discussions I guess.

The short or long term negative impact of any feral animal on our native wildlife, is shocking, to say the least. I think we all agree on that. My views on feral animals are that yes, the situation needs to be improved by whatever humane method advisable, but it needs to be done in a controlled organised and supervised way.
I think domestic (pet) cats are a separate issue. Practical suggestions that other members have already mentioned, compulsory: chipping, registration, desexing, curfew or confinement in place and having all this enforced (with monstrous fines), is at least a step towards improvement for our wildlife. But, until things like that are propelled forward however with appropriate funding in place etc, it’s all going to be small steps by positive suggestion.
I can't see there ever being a point where having a domestic cat is banned or abolished entirely. Neither should they be in my opinion. Would another non-native animal then move up on the hit list do you think if that were to come about, domestic dogs, farm animals?
Everyone is entitled to an opinion naturally, but it’s my bet far more ears and eyes would stick around to read and mull over the benefits of cat curfew, as a bare minimum for example, as opposed to just an “off with their heads” approach. Inflexibility will only provoke the same, and you will catch more flies with honey in my opinion.
I was interested to read your story sparrow about your son-in-law because I had a similar incident a while back. I had a friend who has pooh-poohed for years, my choice of confining my cats. When I say “confined”, they have a rather elaborate enormous run connected to our house. I am luckier than some to have been able to build that, although it really wasn't very expensive - but I also take the welfare of any animal very seriously. Anyway, this friend was just not swayed by the thought of wildlife, birds etc being harmed by their night roaming cat. They did however, have a big problem with all the vet bills arising from their cat being beaten by another every couple of months. You can see where this is going I bet. I couldn’t appeal to their heart initially, but after numerous friendly discussions, convinced them how much they would save if they started curfewing their cat at the very least, so I guess I appealed to their pocket. They tried it, they liked it. Now, their cat is no longer curfewed at night, but actually remains inside 24/7. Sometimes it can be the sales pitch. One "win" is better than none in my book any day.
Speaking of pooh-poohing, of a different type ,
I'd be interested to see the percentage of toxoplasmosis directly contracted from by cats vs other means of contracting the disease.
i.e.
Cats are not born with toxoplasmosis, they are definitive hosts of the disease after consuming an intermediate host such as a rodent for example.
If a cat does eat a rodent and becomes infected, that infected cat will only continue to shed the toxoplasmosis organism for a few days, in their entire life. They will not continue to spread the disease throughout their life and unless sick, their immune system will kick in and restrain the oocyst stage of the organism, the bit which comes out in their faeces that can spread Toxo.
T. gondii is not located in fur, only in faeces and indoor cats who don't hunt or eat raw meat, are unlikely to contract the disease.
According to my GP, Vet and a lot of information on the internet, it is actually less likely to contract Toxo from a cat, than it is from raw or undercooked meat.
You can only contract Toxo from a cat, by directly ingesting their faeces. To prevent exposure it's recommended:
Two interesting reads for Toxo are below. I forgot half of what was told to me first-hand, so had to jog my memory a little/lot.
http://www.myvmc.com/diseases/toxoplasmosis/
http://www.vet.cornell.edu/FHC/health_resources/toxoplasmosis.cfm
Just for interest sake, it was fascinating and horrible all at the same time to also read in separate articles, that recent studies have shown evidence to suggest that the Toxo parasite, when present in a rodent, can actually make the rodent "think" it is sexually attracted to a cat. Nasty clever little parasite!

Birds generally have very high tolerance to 1080... in fact i believe exposure to sublethal doses may even increase resistance
http://www.feral.org.au/wp-content/uploads/2010/07/LC0300.pdf
'Species that may be exposed are the ground feeders and carnivores. However,
many of these species have a high tolerance for 1080
(common to most birds) which provides protection from
baiting programs. For example, a wedge-tailed eagle
would have to eat 7.5 kg of poisoned rabbit at one sitting
to be killed by 1080. This is 2.5 times the average eagle’s
body weight. This makes their poisoning by secondary
effects highly unlikely, if not impossible, using baits at the
prescribed dosages. In addition, carnivorous birds also
have a tendency to vomit after ingestion of 1080, thus
further reducing risk. '
http://www.environment.gov.au/resource/national-recovery-plan-wedge-tailed-eagle-1998-2003
'Although anecdotal reports claim that wedge-tailed eagles have died from eating carcases of animals poisoned with 1080 (sodium monoflouroacetate), no post mortem results have confirmed this (over 20 have been carried out on eagles dying from unknown causes including several suspected 1080 kills). Eagles show a high physiological tolerance to 1080 (McIlroy 1984) and poisoning programmes carried out according to legal guidelines are unlikely to directly harm them. However, indirect harm might occur from the reduction of the prey, the intention of the poison. Nestlings may have a lower tolerance, but since they are fed live-caught prey, the potential for their exposure is lowered. '
That is interesting zosterops and hopefully true for the large part, though Shorty seems to have seen some disastrous effects. I remember a friends Kelpie surviving after eating a whole packet of Ratsak that he found under the house ..... did a fair but of vomiting but those Kelpies are made of stern stuff.... in the end it took 5 bites from a tiger snake to kill him . He killed the snake though
Probably just aswell as it was in the outdoor loo in a holiday house down in Margaret river and the family were all staying there at the time

I am pleased that this thread has turned up all this discussion and information. AnnieJ I liked your input, but in regard to the advice that "you can only catch toxo by ingesting cat faeces" , isn't that playing it down a bit? It may well be true, but what about sandpits that both children and cats are drawn to? I don't know whether they still have them in pre-schools and kindergartens, but they are certainly in many suburban backyards.
Birdie, i am not a ranger. (might need to re-read my post )
Zosterops, a very interesting read. Let me expand on the fox.
When i told the ranger that i had found a fox dying from 1080 he told me it was not possible as there were no rabbits that he saw eat the bait that night (they only bait the carrots at certain times and use motion cameras). He also said to me that the fox would have had to eat more rabbits than is capable to be affected. When i took him to the fox he confirmed it indeed was affected by 1080.

To my knowledge these days sandpits have to be covered after use and it is a health and safety requirement alonng with the requirement for handwashing after play and handling ... and that is also why so many people like the clam shell idea ...so as to cover the sand when not in use. It most certainly is not playing it down, as the fact is the toxin has to be ingested ... whether it comes straight from the hands or not. That is why the good hygiene is so important and why all pregnant women are warned to wear gloves etc when handling kitty litter as the organisim can cross the placenta like Listeria can .

Oops..... not sure how I could have read that and come up with that conclusion Shorty ... I did take a very big tumble while out birding today. but I didn't land on my head ... however some may think that I have my brain in my butt at times
With regards to the fox ... could he not have just eaten the bait if he was hungry? I thought the 1080 was primarily used for fox baiting anyway? at least in WA I thought it was

No worries, Birdie. I just wanted to clear that up.
The ranger said no animals were seen on the camera? The baits were intended for rabbits and were in an encloser a fox would not fit in.
I am afraid 1080 is used for many animals, including natives.
Here is just one of many examples.

Foxes are extremely susceptible to it so it's not surprise though i assume the currawongs and ravens which could have fed on the fox would have been fine.
That link above clearly shows the ignorance of the mass population :
'As a wildlife carer myself I can assure you you could not be further from the truth. Perhaps you can also tell us all how it is that Wedge tail eagles die or worse still produce unfertile eggs. And what of the owls, night jars, quolls, if was to just eradicate the feral cat I would be 100% in favour of it but in reality it does the opposite it kills off the wildlife that Tasmania is so well known for. Perhaps you should watch a animal die from 1080 then and only then you might be half informed on what it really does.'
,,,
Many native animals of the west coast have near complete immunity due to coevolving with Gastrolobium species which contain the substance naturally, in fact i seem to recall some areas in wa being largely cat-free because the local herbivores have accumulated the toxin in them.
i found a link to something similar

Zosterops, the link i provided was to show that they use 1080 to target Wallibies and Possums due to crop loss, not the comments section.
