The vet has suggested dietary supplements. I am still waiting for the Nutribac to arrive, but they do have Nutri-gel. It's a high calorie supplement used in cats and dogs.
She suggested I look at the ingredients first to ensure there is nothing that might harm a snake. Any opinions on this MOST welcome - would you give this to your snake?
