Well, it's depend what a kind of lizard is: But in most cases are they carnivore or omnivore - What I had, was a omnivore: Where from beginning to first with small insects, worms and with some veggies/fruits (salad, tomatos, apple etc.) - After a specific time, if he/she bigger become is: Then also with baby-mouses. But of course never out let the Vitamin/Mineral-powders, okay?
