Jason, try putting a litterbox where ever he is choosing to go at night. My ferrets on occasion seem to tire of certain spots and start somewhere else. I have learned to move litter boxes to where they are going and they will then use those. Also if it is somewhere you really want to discourage, try putting a bowl of his food there or some old towels (bedding stuff) because most ferrets wont "go" near something they perceive as a food or sleeping area. Usually this will help significantly. Good Luck, Karla Meep and Daisy [Posted in FML issue 2330]
