How do we know this ? We have 10 snakes and various lizards and frogs. We have been to every pet shop there is in Knoxville. The Critter Barn is in a small block building and looks like a hole in the wall, but this is probably why they can keep their prices so reasonable. You can get a full size ball python here for $89.00, try that anywhere else in Knoxville. Everyone else wants $129.00 and up ! They also make sure the snake is eating well before you get it, and they are there for you if you need advice or have any problems. They have tropical birds, a variety of rodents, tropical fish, Hedgehogs, ferrets, exotic spiders and centipedes, huge hissing cockroaches, snakes EVERYWHERE. Lots of supplies too. No dogs or cats, and rarely a rabbit, but if you're really into reptiles, this is a great place.
