So I tried to feed my new boy and he didn't take it.. He looked ready but I think the rat was too big.. My BP is 300 grams and I was told by a friend that she feeds her BP's small rats to hers that are the same size.. I think he could get it down but it just looked a tad too big.. he has been on a diet of rat crawlers/pups and he turned his nose at my offering.. I think I'm gonna try again tomorrow with an adult mouse..
