So my little Dante isnt coming today =[ and he was expected to come before Christmas then today but nope =[ Question do you have a regular herp vet you go see for checkups or problems or just to any vet and get him checked out by a random herp vet?
It would be a good idea to find a herp vet that has chameleon experience so that you dont have to scramble to find one in case of an emergency. A back up vet would be a good idea too.
Find a local vet who specializes in exotics and things. Usually they have experience in Chams but so would normal vets my guess. Just as Kara said, I would check around and find one with knowledge and keep them as your vet as long as you comfortable with them. I suggest as well the back up vet idea just incase you need it.
