I like cats, dogs, and birds but in different ways. Dogs are nice because of obvious qualities: loyalty, protectiveness, obedience, etc. I love birds, always have. But I think they (with a few exceptions) make horrible pets. They take the most care out of the three, cost the most (usually), are the loudest (again usually), and can give a puppy a run for its money in the amount they can chew up. Cats are nice, cute, and clean(ish) but that's it, they don't really do anything. I would have to lean toward dogs out of the three because they are the most practical (by that I mean they actually can serve a function, protection.)

If I wasn't including practicality, then I'd go for cats, and if I didn't have to take care of it or listen to it (when it decided to squak for 10 minutes straight) I'd go with a bird. So they all sort of have their own ranking. But in real life I'm only likely to ever own a dog again.
