I am all for killing feral cats.
Why? Why not have them captured by groups and then have them spayed and neutered and clip their ears. Those with serious diseases like Feline Leukemia can be put down if need be.
Feral cats are the result of idiotic pet owners, just like most dog bites are the result of idiotic pet owners, which result sometimes in some Dogs that have to be put down.
I am all for human safety, but just killing animals indiscriminately that do not pose a threat to Humans are habitats, like these pythons that got brought to Florida by stupid people (which should be killed given threat to natural habitats).
I adopted a feral cat. It took a long time to get her to settle down and let me approach her. She will never be really tame, but might be my most affectionate cat now. She has completely bonded to me, and loves to be held. She never goes out.
