Aquarius is the friendship sign, so this is a pet who will get along with everyone. Cats, dogs, rabbits, porcupines: put your Aquarius pet in the mix and he'll attempt to get along with them all. At the very least, he'll ignore them. Not on purpose, but simply because he's too busy chasing butterflies, trying to climb to the highest bookshelf, or digging for buried bones to be bothered. This IS a trainable pet, however. Aquarius is the humanitarian sign, so yours would make an excellent guide dog, therapy dog or pack leader at an animal behavior school.
