Yes, it's a "thing" called venomoid. Many people believe it is inhumane, and may even affect the snakes ability to digest prey. It can never be fed live again. AND, you're trusting that vet a WHOLE lot to have done the job properly so the glands don't regenerate down the road. A venomoid should still be treated as hot. Oh, and I bet those fangs still hurt like heck.
Ha - Ed and James are faster than me!!
