I've been doing a lot of research because I am also planning on getting a savannah and I read that it's not good to feed your Savannah hard boiled eggs. The list of bad feeding includes hard boiled eggs chicken parts and dog and cat food. One surprising fact that I read is that they are primarily insectivores in the wild although many people feed them mice and rats as well. When I first started looking at monitors I thought they ate only mice and rats like snakes do but they need more variety.
