Ok, unfortunatly (or fortunately ) I dont have any pictures, because when I noticed this, I was already half way done cleaning it.

My breeder size albino female had kind of weird looking poop today. On one part of the enclosure, there was a big pile of "normal" poop that I cleaned, and then I noticed 2 pieces on the opposite side, that were both grayish and composed out of hair.
From time to time I find poop that has more hair in it then average and I dont worry about it, but since this time it was totally separated it got me kinda worried.
I was wondering if it could be a regurgitation, but somehow I doubt it, since the last time she was fed was last friday.
I know its hard to give an opinion without a picture, but what do you guys think? This friday is also feeding day, so I am wondering if I should skip feeding her this time.
