We have had Slithers for a little over a month he just came out of this first shed.. And now when we hold him he seems to Yawn..( opening his mouth periodically ).and quite frequently ... He is a new snake and it is a new behavior just wondering if anyone witnesses this before... However he seems to love being held for the simple fact that he doesn't try to get away and he pretty much just holds onto our hands..just making sure it's his behavior and nothing medical..
