Its like 85% for Dogs. Last year I think there was 1 or 2 snake vendors and a big trailor with venomous snakes you could go in and look at. Some stuff for Saltwaterfish, as well as Sugar Gliders and Cats.
This year though I dunno. Its worth it to go though just to get out of the house and do something. Plus if you have a dog your allowed to take them in with you. They do sell alot of supplies like bedding and cages and such. Pretty sure though no live feeders but not 100% sure....
