I have a very young garter snake that has this strange section about 3/4 down his body. Its this little area of kind of pinched looking skin. Its kind of hard to describe. The first thought I had was that he could be dehydrated but he has two water sources which i have specifically shown him even though i know good and well he can find them alone. He eats flawlessly and I feed him usually every third day. He has been eating tilapia and worms and the occasional pinky leg. I dont know how concerned I should be with his problem or if there is anything I can do about it. He seems to move fine and he is growing. Does anyone have any thoughts on this?
