I'm definitely an animal person, though I grew up in a house full of cats (which didn't stink, by the way). Hating an animal based on its species seems rather harsh to me. Hating an animal at all seems rather harsh; an animal is an animal, and behaves as an animal does with no malice. An animal cannot be evil, because evil requires intelligence, more intelligence than any animal possesses.
I only have a bunny right now, but I plan to have both cats and dogs when I can afford a bigger place. And chinchillas. I also need chinchillas.
I will say, however, that dogs aren't really loyal; they're subservient. Their owners are the alpha dogs, so to speak. Nothing wrong with that, and nothing against dogs at all. But many people mistake their subservience for love and loyalty.
