My new reduced ball refused a rat when offered in his cage and in tongs. he seems pretty happy, so I don't think it's stress related. When i walked by the rats enclosure while carrying him he darted out towards it with his tongue flicking like mad. he's been raised on mice and it's been at least a week since he's been fed. Is it possible that he just is refusing the meal of a rat, or does this sound more like a general refusal.
