PETA has done some horrible shit for sure, but the pet thing is usually taken out of context.

PETA has made it clear that they aren’t against humans having pets, but they are against breeders using various animals as pet baby mills with no regard to the animal’s health or well being. They are also against abducting animals in a manner that might be painful to them.

Whether you like PETA or not, I think they do hold a good position on this topic.
