I keep a couple of cans of ZOOMED Tegu & Monitor food and/or reduced fat cat food around for emergencies. I do not give it to my tegu regularly. Sometimes you run out of food and all the pet stores have closed.
I have ordered 100 frozen mice and 25 frozen quail chicks. Hopefully I won't have to use the canned stuff.
PS: The rest of my animal's diet consists of insects,eggs and various fruits fortified with vitamin-Ca suppliment. My animal is only about six months old. He loves his fruit so I give it to him.
