i fed my snake a fuzzy for the first time 6 days ago, and he has pooped a couple times since then. he has not been very active this week, so i have been checking up on him often. found this in his cage today, looks like a dried skin casing of some sorts that’s about half an inch. it definitely has a weird sweet smell to it, but i don’t know if it smells as rotten as a regurg has been described to me. i’ve included a picture, what do you guys think ? i’m worried
