My self-caught red-sided garter that I caught 2 1/2 months ago has not shed yet. I read that they should shed every month or two, but his aren't blue yet or anything. Is this normal? He seems healthy and is happy in his home.

He has stopped eating, but i'm assuming that's normal 'cause of the time of year. Starting my "mini brumation"(drape a towel over his tank and remove heat source for a month)this week
