OP, you're in good hands with Deborah. She helped me get an 11 gram trouble eater eating like a champ. When he came to me he had only eaten a few meals and was TINY. Now, 9 months later, he's almost 60 grams, has only refused twice and is an awesome little member of the family. Follow Deborah's advice and you'll be in great shape.
Good luck with your hognose, they're seriously adorable little snakes.
