Hi Cindy, I had the same problem in our ferret room as they are free roam and were doing a little number under the little dresser we have at the window for the kitties that like to stay with them. We put a small cat litter box under there and clean it out 2x a day and no more poopie problems under there. I know that my not be the best solution as you can put bedding, food etc to deter them but then I figure they will find someplace else to go. It worked for us anyway.
