When I was little, my dad bought me a puppy, thinking it would help "open me up." It didn't work at all. I totally ignored the thing, so it ended up being his dog.
I don't do pets. It takes effort to empathize and communicate with people, and that's hard enough. But animals? Forget it. They don't use or understand language. They're not sentient. They s**t and piss all over the place and make irritating noises all night. At least comatose humans stay in one place and don't make much noise. Pets aren't for me, and I've had people question my humanity when they find this out about me, and it really pisses me off.
That said, I do better with cats than dogs when I go to someone's house. My dad never got a cat (too "sissy" for him, I guess) so I have virtually no experience, but it is possible that I might be a cat person, but just a little. Not enough to go out and get one. I don't think I'd be capable of caring for it. I'm afraid that I might end up neglecting the poor thing, unwittingly of course, which would be tragic.
