"I cut these liners to fit the hi-bac litter pans and they are great. I have 2 rabbits and they use the small litter pans like crazy. Usually I just dump out all the litter because it is so wet in only a few days. When I use the liners, the pans are ready to fill again immediately. No more crusty litter stuck to the bottom, which is really gross to clean out. Since the papers can be cut, I get about 8 litter pan liners per sheet, which is nice. My bunnies don't dig and chew on the papers, so I don't have to worry about them eating the super absorbant core. That could be bad. All in all, these liners are great!"
