we recently, bought two wonderful balls and we were just wondering, when we go into stores and such and look at others in the cage most of the time, the snakes excrement tends to look kinda like the mouse but ours seems to be a little runnier at first so i was wondering if this is healthy or not, and if its not how do i help them?oh and i was also wondering what that white stuff is that also normally isin the cage a couple days after a feed?
