Raised three fox squirrels one time. I bottle fed them and cut the whole milk about half and half with water-I think. They cant hack whole milk and will die if you try and give them that. You have to cut the milk.
Problem is, when they crawl on you they poop a lot. The thing that amazed me was their paws. They have those little knuckles and can pick up things and handle them. They can crack open a nut so quick it is unreal.
