Background: I have a male albino ball who is pretty under weight. He has always given me a little trouble when it comes to eating. When I first got him he wouldn't eat for a month and a half. When he did start he would only eat sometimes and others refuse. I chose not to breed him even though he was producing plugs because he was only about 450 grams (and I only have normal females right now). I don't know if it's normal or not, but about the time my other balls started breeding he went off feed and didn't eat for a few months. About a month ago he resumed eating and is doing quite well. My problem: He is sitting around 475 grams and is somewhat triangular so I know he needs more food. He will only eat live mice, and will never eat more than 1 at a feeding. I am getting the largest mice available, but the biggest I've been able to find is about 40 grams. Once he eats one, he shows no interest in anything else. I have tried a couple of times to get him to take a small rat (I know there are fuzzies or pups, but none of the pet stores around here have them, just small), but he shows absolutely no interest in the rats. How can I get him feeding more? Sometimes he will take 2 mice a week, but usually not (offering Wednesday and Saturday). Any tips on how I can get him to switch to rats? Thanks
