You know what else will help, starting now and continuing until he's on adult mice, I'd slit the mice. Take a small scissors and cut about four slits through the skin of the mice's backs, and even the skulls. After a regurge, I even slit the sides of the mouse for about a year. It makes them _way_ easier to digest. I've never had a problem with a snake taking a mouse literally rolled in Nutribac till it looks like a powdered sugar doughnut, but you need to very gently rinse the snake under the faucet in room temp water before replacing him in his viv because Nutribac plus mouse juice is like Superglue.
