Are you a beginner in reptiles ? Collared lizards are a little small since you want a 1 to 2 foot lizards, but boring they are not ;) Tame, most are, but some will never be. Feeding is quite simple, a couple or crickets in a shallow bowl, mealworms, waxworms, grasshopper and superworms. For most collared, the bowl is an option since they are eaten up as soon as the lizard see them. Still interested ?
