I once rescue a emiciated baby Sav from a pet store... It was very skinny...all you could see were bones and skin. I came home and gave it water, but when I fed it two mouse pinkies, it regurgitate all the food. For a while it could only hold down one pinky at a time each day. AFter it has gained back some weight I started giving it fuzzies all it could eat. It recovered...I know because he bit me! Haha It didn't hurt because he was small, but I know he was back to normal. After I had him for a while I gave him to my friend who loves monitor to look after him.
