Sry I cant see the spots.I hear a lot of people talking about feeding cat food to their tegus. My vet at UF suggests not using cat can food it differs from can dog food. She only suggest feeding it at a way to help add fat. But that if I choice to use can food to use a high quality can dog food. She gave me a brad but I'm not sure if its allowed thing to say.
What kind of bedding are you using for your tegu?
Looks like shavings. Do you know the dangers in using shavings?
Good Luck.
