No, it is not. Though you just have to be careful and use hand sanitizer while handling different animals while you are there. Some vendors are not always that great, aka dirt merchants and they sell sick animals so you don't want to get anything on you and transfer it to your animals when you get home.
I think it's a great place to get a snake, I like seeing what I am purchasing in person rather then getting something online personally.
Also, I kept my 7ft peruvian in a 4x2 boaphile. The others are all in my 41qt snake rack.
