Dogs...and horses. Cats are pretty dirty IMO. They have so much bacteria in their mouths, and then they lick themselves. They step where they go to the bathroom, and then you hold them and they put their feet on your face. Yum... Plus the majority of them are just plan NUTS. You try to hold them down to take blood or whatever and they pee on you or try to eat your face. Try to give them a bath and they try to eat your face again. But anyway... Dogs are cool for the fact that if you have a dog door, they will go outside and usually entertain themselves. And horses are just funny.
