By the way...do you know what he was being fed? What size of mice, and live or pre-killed (fresh or frozen-thawed)? I'm assuming they didn't give you a feeding
record either and this is important for your success in feeding a snake, knowing what they prefer & are used to. Most corn snakes are great eaters (but may
not be if they have a mouth issue as this one appears to) and very few refuse to eat f/t mice (frozen-thawed).
