I very recently got a Corn Snake, about 5 years old, and he recently went through a bad shed with his previous owner. His breathing seems fine, but he keeps making squeaking/wheezing noises- I can't see anything, but I'm thinking his nose is blocked a little by some leftover skin. If this is the case, I've read that a damp pillowcase might help remove it, but I'd like some further opinions before I try anything. Thanks!
