I would have voted 'born loving them all' except that I'm not a fan of lizards at all, not overly fond of monkeys either, and can't get quite as attatched to most fish or birds as I can other critters.

I love pretty much most things with fur/hair, cats, dogs, guinea pigs, degus, big hairy spiders (as long as they aren't crawling on me), boa constrictors, porcupines, turtles, as well as the typical exotic cuties (koala, panda, penguins, cougar, bears, etc).
