ACK!! A vet told you WHAT?!?!! Please tell me they did not charge you for this gem of wisdom . That is truly frightneing that a vet would advise this. My snakes, corn and bp, eat mice. That is it. No snacks. No worms. Just mice. And they both seem to doing quite well with this system. My hunch is that there are other snakes here that are on a similar diet and also doing quite well.
