This is no surprise since they are inexpensive, have good temperament and are relatively easy to care for. As for feeding, they will accept almost anything they are given. Unfortunately, we have all seen monitors built like bowling balls because of their tendency to be overfed. It is perhaps not just how much, but what type of food we feed our Savannahs that matters most. In order to properly care for them at home, we must look to how mother nature cares for them in the wild.
Savannahs are the white throat's smaller cousins which inhabit areas further north.
This regional difference is one reason that current information is inaccurate. During this period of feasting, a Savannah uses its keen senses of sight and smell to locate delicious insects. Believe it or not, there is no evidence that they eat vertebrate prey at all. Wild Savannah Monitors primarily eat insects and smaller percentages of eggs and snails. The lizard will eat up to one-tenth of its own body weight in a day to store fat for the period of fast.
