ok so your argument is all cats should live inside forever? and that's also not cruel? do you have a real solution to this issue of natural instinct? because locking an animal up for the perceived safety of some random other animals which may or may not be endangered by the locked up animal seems really cruel to me. obviously i dont encourage letting your cat out and saying 'go get em tiger!' but i'm not going to agree that keeping a cat inside all their life is humane. i've lived with over 20 cats and some like it inside all their lives, some hate it. these animals are from the outdoors and we brought them inside. seems really overly compassionate for some random birds and rabbits to then keep the pet you are responsible for in a state of perpetual misery. i'm sure we can strike a balance. cats can go outside sometimes, as a treat. if your cat brings back a bird every day maybe address it, but shooting cats is not okay and this argument that they are sport serial killers is the worst justification for shooting animals (which is the take you are supporting with this post, for the record).
