Any animals are aloud whether it be dogs, cats, birds, lizards, or whatever. There aren't any size restrictions, just breed restrictions and you'll probably have to pay a fee, but it should be a one time thing. There are ways to get around the breed restrictions though if you have or want an animal that they don't allow. Most of the time, as long as the animal isn't causing any problems, then management doesn't have a problem. Just make sure you clean up after your animal because it can get pretty bad in the summertime:)
