Ferrets are naturally clean-ish animals. They like to do their potty business in the same places, and if they can’t find that place, and they won’t look too hard, they back into a corner. So when the girls are having a run around the house, the easy thing to do is put something in each corner for easy clean up if they poop. I got pee pads for this exact job. Major fail! The girls like the smell and feel of the pads, so instead of doing their business on them, they chew them up and hide underneath them. But the pee pads were still a great purchase. Why? This is why.
