Savannah Monitors are primarily insectivores in the wild, there is however, some controversy about feeding rodents in captivity. This is a long winded and foolish argument.
A properly supported Monitor can handle mice and rats in their diet without any problems. However, the vast majority of keepers do not provide the correct housing for their captive lizards and the resulting health issues are often blamed on the rodent diet, when in fact improper husbandry that brought on the failure in the animal's health. Be sure to read the dehydration and gout page carefully, or your lizard will not live to be very old.
A proper Savannah Monitor diet would consist of Roaches, Crickets, Night Crawlers (Large earth worms) Mice, Rats, Snails, Garden slugs, Superworms and Locusts (where available) and certified chemical free organic whole Shrimp, Crabs, Crayfish & Chicks.
