I simply do not believe that feral/wild cats only live to 2 years. "Down under" these animals have a perfect environment. It is illegal to kill or trap them, there is no rabies, no natural predators (with the exception of the odd dog and dingo), lots of prey, and a good climate...what more do they need? Hunting for domestic cats is instinctive and does not need to be learnt, unlike their larger cousins.

I don't quite understand why you think you have got on your soapbox? As far as I can see, there are two main problems with feral cats. The first is that they are a result of mans "inhumanity" to our feline friends - in the form of bad management and abandonment. The second is that it threatens native fauna populations. Who can argue that these aren't problems?
