Actually, if someone knows how to take care of an animal properly, I'd think they would be better off than if they were living in the wild (generally).
Personally, though, I don't really like the responsibility of taking care of a pet. I currently have 2 cats, 2 rabbits, and 1 gerbil, all of whom I've adopted from 2 local shelters.
Another gerbil (from the same shelter- my remaining female gerbil's sister, presumably) died within the past month. As death goes, I suppose it was as easy as it gets... that morning, she was scarfing her breakfast out of her dish as usual, and she had enjoyed a romp out of her cage (in a cat-free room) a short time before. There were no signs that she was sick. And she was 3 years old, which is pretty good for a gerbil. She was just laying on her side in the cage, dead, when I got home.
I love them all, but it bothers me that I will always have to make decisions about their welfare for them. I'd rather advocate for animals by just avoiding harm to them, whether it was by being nearly vegan, or by growing at least some of my own food with no heavy equipment to avoid killing them in th field or in food storage facilities.
I don't like to see animals bred while others die for lack of homes, either- even though I understand that if someone really had their heart set on a particular kind of companion animal, they might not be able to find what they want in a shelter. I suppose I can sort of understand going to a breeder in that case. After all, I've "rescued" (adopted) cats, rabbits, and rodents, but no dog rescue outfits have gotten on my case for "not saving dogs". (I don't have anything against dogs- they're terrific animals- but at the moment, I'm not in a position to take a dog in)
