You can go to the pet store and buy live crickets for feed.
My baby lizard won't eat the dead ants I put in his cage. I cannot find/catch any crickets or flies for him to eat. I don't want him to starve. What do I feed him?
Do what Ancient Hippy said .. Or call your Vet and ask him or her.
If you got the lizard from a breeder or pet store, then DO NOT feed it bugs from out side! She will probably be ok for a couple of days. I would buy meal worms or small crickets from a pet store.
