Wasn't PETA the ones that wanted to make pets legally "companions" so that the pets had rights above other animals or something. These people are nuts. Loving animals is great but these guys jumped ship a while ago.
It's simple. Eat Kosher and your problems will be solved. There are certain rules on how you kill the animals and what animals you should and shouldn't eat. It may sound radical, but if you really truly look into it, it makes a lot of practical sense.
