Yes, they are USDA licensed and also US Fish and Wildlife Service licensed...? Not sure what the second one is lol.
I just spoke to a friend/fellow breeder who has purchased 2 hedgies from them, she said they were great to work with and their hedgies are very healthy and well-socialized. She also said that the lady that owns Beach Bum does that as her full time job, just taking care of the animals. She didn't seem to have anything negative to say about them, so there is one experience for you, I'm sure someone else here has more information.
