I own just one ball, Barnaby. I have had him since the 31st of August this year. We last fed him (a rat) on the 3rd of November. He has been showing signs of shedding and I thought he would've shed by now but he hasn't. Also, he has not 'done his business' this time after being fed and his tail looks a bit larger so I think he might be constipated. Should I worry? By the way he is a 3 yr old, approximately 3-3.5 foot. He was last weighed recently at about 930 ish grams (sorry I don't have the exact weight with me) which is what he is about usually after a feed. Thanks Ally
