I have 2 large females that are rescues I feed them Med Rats till they caught up on weight Now they are on 1 small rat a week. I want to avoid nonfeeding issues with them like in one of my other female who has now been off feed for 26 days. For what ever reason she has gone to eating only once a month and she is only 962 grams and a "08". She will only take a adult mouse and a large rat pup.
