Had an awesome girl that'd eat any f/t you'd give her and never refused for the first 1.5 years I had her. She went off feed for about two months when she was around 1100g. She wouldn't even eat a live small rat, but eventually ate a live rat pup when left alone with it for 30 minutes or so. I put her in a smaller tub shortly after she ate the rat pup and she started eating again from then on. Could have been her fast ended, she needed a change of scenery, she needed that live rat pup to get her started again, or a combination, who knows.
