I recently started feeding my savannah monitor eggs once in a while. i know they like them, but i've also read that too many can cause problems because of the high fat and cholesterol content. so what i've started doing is just using the egg whites. he still gobbles them up. is this a legit food source for him? he still also gets mice and grasshoppers, i'm just wondering how good egg whites are for him and how often i can feed them to him. he is a little over a year old and about 20 or so inches long, weighs about a pound. thanks for any help
