There are snakes like king cobra who can eat monitor lizards. Lizards are opportunistic creatures and then knows that there is a lot of predators that can harm them.

So they lay low, and they eat whatever they can. Small snakes, eggs, small lizards and rats are all included in their food list. This food perfectly fits their diet because lizards like monitor lizards can get them without fighting against big predators like a lion or tiger.

Eating a few rats will satisfy their hunger, and also gives them enough energy to move around. Apart from Komodo dragon all other big lizards avoid going near the territory of lions, tigers, hyenas unless there is a strong reason behind it which is usually a prey.

Big lizards eat rats, and they do it quite often, but lizards are not their primary food. Since lizards are opportunistic creatures, they eat whatever they can. Rats are small compared to lizards, so rat becomes easy prey to these big lizards. Lizards are often seen to eat rats; it’s because they don’t have other options most of the time.
