I have had my black and white Tegu for nearly 2 yrs now but for some reason he has stopped eating. I know that they may slow down on eating during the hibernation period but he hasn't eaten in about a week and a half. He didn't do this last year so it's kind of worrying me. He doesn't mind me opening his mouth and everything so i can try and force feed him but I'm afraid to do so if he chokes, so I'd like to know if he's acting on normal hibernation behavior or if there really is something wrong with him.
