My ball stopped about a month ago. I warm up her rat, do the zombie dance and if she doesn't strike at it, leave it on a cardboard mat in her cage for the evening. Since she has taken a break (did this last year as well), I attempt to feed her when one of my boas are due to be fed. That way if she refuses, then one of the boys gets his meal before I go to bed. If the ball eats then the boa gets fed next day - they will never refuse a meal, such great eaters unlike the pain in the butt but adorable ball!
