We are moving the first week of May in to a trailer. It has two bedrooms one for us and one for the "pet room" which is where the dogs' kennels will be and where Hobo's tower and one litter pan will be. I plan to put another litter pan in our bedroom on the opposite side of the house. When I move him in do I need to shut him in the "pet room" so he knows where his litter pan is or will be be fine to wander the whole place and go in either litter pan?
