Why is the breeder against UTH? Taking your snake to dance class is putting alot of stress on your snake.Ball pythons are not used to being bounced around as such when you are dancing.Leave your ball python alone for a week or two to allow it to stop being stressed out.Then try to feed it and see how it does.One more question in your first post you said your ball was 220 grams right? How is 190 grams a weight scare for the vet to be concerned to force feed the snake? Your vet is putting even more stress on the poor snake.I am not wanting to sound rude here but i think you might want to get another vet.Just because the snake lost maybe 30 grams is no reason to go straight to force feeding it .
