Hmm... we have that problem with Abby maybe once or twice a year, when her hair gets too long around her bum. Just get it shaved or shave it yourself. It looks funny for a little while; as any shaved bum WOULD... but it's better than her sitting on the carpet and getting poop on the carpet...

One more question.. is it... *wet/diarhhea*ish poop? Or is it just normal bunny poo? If it's normal, its probably just cuz there's too much *hair*.
