Feral cats in Australia are considered one of the most serious threats to our native animals. When you consider that cat numbers could be around 23 million it's not hard to understand why so much of our vulnerable wildlife has disappeared or is seriously threatened. I love cats but know only too well what perfectly equipped predators they can be so mine live strictly indoors. Of course the whole reason cats are a problem is mostly down to people dumping cats or kittens in the bush, a totally irresponsible act that has lead to a major environmental problem that now seems almost impossible to contain. Has the cat has become top predator in Australia ? Sadly once the rabbits were all but exterminated from the continent cats then turned to the next best thing. Our native birds, small marsupials and lizards are all on the menu. While the feral population is exploding we as cat owners can at least act responsibly if we don't want our cat and hand it over to a refuge. Surely that can't be too hard to do.
