okay we rescued a new tegu a few weeks ago. He is said to be about 5 years old.Eats like crazy, very hungry.Diet before us consisted of ferret food :roll: .He is now eating some fruits, chicken,beef heart,mice and ground turkey.I did a search and found few answers.Compared to my tegu Piggy he looks to be on the thin side.I know they store there fat in there tails.But what other ways can you tell if a tegu is under weight.Thanks alot for the help!
