Good question. First, the word "pet" must be emphasized. In our opinion, it's not a pet unless it can be interacted with and cared for in a relationship that is MUTUALLY beneficial. Beyond that, if it's not a dog or a cat, it's exotic. Actually, we're now even seeing the occasional house cat because to some owners, their cats, regardless of the species, are exotic! The most common exotic pets we see, (just scratching the surface), are parrots, macaws, cockatoos, finches, canaries, ferrets, rabbits, guinea pigs, rats, hamsters, sugar gliders, snakes, turtles, and lizards. We have seen scorpions, tarantulas, bats, bears, tigers, otters, and other odd creatures, but they are, in all honesty, the exceptions. Here at Avian & Exotic, we'll see anything that meets the criteria of being "pet" material that we feel COMPETENT handling. We won't take care of any animal that we don't feel we have adequate knowledge of. And, just in case you have something we don't feel comfortable with, we always know exactly who to refer you to.
