Domestic cats and dogs wouldn't exist today without the alterations arrogant mankind has impinged on them through breeding, confinement, association, etc. Talk about closing the barn door if you wish, but the horse left a long time ago. If a cat is going to live in my house, with furniture and drapes and my thigh and little kids around who don't know not to "ask for it", I will have them declawed. The dog will learn to go outside to pee and poo and shut up when I tell him to.
