In regards to ferrets using the carpet around the litter box as toilet paper--I went to a carpet store and bought 2 sample pieces of carpet(the ones that they use as displays) for $1 each. I put the litter boxes on top of the sample carpet and my ferrets wipe their bums on that. Its more convienent than newspaper and it is easy to clean with any type of spray on-wipe off carpet cleaner found at the supermarket. [Posted in FML issue 1171]
