1) How do you sex savannah monitors? I have looked all over the place, and cannot find anything.
2) What do you all suggest feeding an adult monitor? Mine is about 3 feet long now, and I fed his crickets and roaches, worms, etc... when he was smaller, but now he could eat thousands of crickets a week, so I have been feeding him mice. Is that ok? He gets plenty of exercise, so he is not obese, which I know can be a prob, but is there something else that wont cost me a fortune to feed him? What abuot fish or shrimp? Would that be ok?
Thanks!

Ok, cool, then I'm not doing too bad, we don't use pesticides because of all the animals, so when we find roaches, (unfortunately frequent) we give them to him. he goes nuts chasing them all over. How about sexing him/her/it?
