I went to a local reptile vet with my gf for her chameleon and asked the vet there and she said just come in for a quick check up and bring some probes and she'll show me for free (besides check up fee, which I figure if I have ANY issue I'll just do that). I'd imagine a lot of vets would be like that so you could call them up and ask. She did tell me that I shouldn't pop them, which I can understand from her stand point. She's giving advice to novices, I could totally see someone getting too rough with a snake when they get home or just doing it too often and causing some damage and then blaming her. I'll probably do that when I'm ready but I'm sure I'll learn how to pop sooner or later, I just want someone to show me in person.
