“What do lizards eat” is an interesting question. There can be many different answers because there are many species of lizards. In fact, there are around three thousand different species of lizards. The carnivores eat nothing but meat. The herbivores eat nothing but plants. And, the omnivores eat both plants and animals.Sometimes people are in such a hurry to get a lizard home from the pet store that they do not sufficiently research “what do lizards eat” before bringing one home. First of all, you can’t be a squeamish sort of person if you want to own a pet lizard. Many of them are indeed carnivores and these eat nothing but insects and small mammals. Some will not touch any meat that has been freeze-dried or frozen, so you have to feel comfortable giving the lizard live insects and worms to devour, most likely right in front of you.
