It is the exact opposite around here. Cat and dog vets are where the big bucks are. Exotics vets are more of a fringe group, and very difficult to find.
Another thing: Just because a vet CLAIMS to be an exotics vet, doesn't mean they actually are! I have personal experience with an "exotics vet" who didn't know jack about snakes... Don't just read the sign outside the vet's office. Do what BG said, call and ASK QUESTIONS!!
