My red Tegu (Gary) is not eating and hasnt for 2 months. He drinks, and roams around, he shed, he loves his warm baths, but turns up his nose at everything!!! He has 120 Degree basking area. He used to eat like a shark. Attacking everything dead or alive. Is he brumating? Ive had boas, beardies, geckos etc, but never had a reptile go off foor for so long, especially a rapacious one like a Tegu. Any thoughts?
