Spot cleaned my BP's tank today and there was a long (3.5 inchs) turd that was not the usual color or size. It was very light grey (the mouse I fed him was white) and seemed almost like a shriveled up mouse. I didn't notice any bones or anything like that still in tact. It was just very long and strange looking. He refused his meal a few days ago (it was a bit large, so I thought it was just too big for him). Tried again today, and he was not interested what so ever, he is usually a very vigorous eater.
