Many monitor lizard enthusiasts enjoy feeding their pets a varied diet of insects, small mammals, and even other lizards. In the wild, monitor lizards are opportunistic feeders that will eat anything they can catch. This diet often includes small prey such as rodents, birds, lizards, and even snakes.
Some keepers find that feeding their monitor lizards live prey can be dangerous and stressful for both the lizard and the prey. For this reason, many people choose to feed their monitors prekilled or frozen-thawed food. There are a number of different commercially available diets that are made specifically for monitor lizards, but most keepers supplement these diets with live insects or other lizards.
Some people choose to feed their monitor lizards a vegetarian diet, which can be made up of a variety of different fruits and vegetables. While most monitors will eat a vegetarian diet, it is important to make sure that they are getting all the nutrients they need to stay healthy.
