i think it's kind of hard to over feed a ball. if they're not hungry they won't eat. one of my girls is still stuck on mice and we're trying to get her up to size by next season. i've always been able to tell when she's hungry because she'll just chill there with her head stickin out of her hide. when she's not hungry she'll be way in the back of her hide, but EVERY time she has her head hanging out, she'll eat. sometimes i'll feed her 2 mice on feed day, she'll refuse the third one, and then she'll be hangin her head out of her hide 2 days later ready to eat some more. lol
