[nibbler100]

so normally when my piggies poop its milk chocolate color but to day when i was cleaning there cage i noticed quit a few where dark.. vary dark.. almost black. There not squishy or diarrhea like just a change in color. should i be worried? i haven't changed there diet at all, there eating and drinking the same as well.

I wouldn't worry about it unless something else goes wrong.
