I bought the playhouse yesterday at my Lowe's on Sale for $199, plus the man gave me an extra 10% off. This playhouse does not have a floor, so I am going to put in a floor (really my husband) that can be removed if needed for cleaning. I also want my husband to add some 4x4 feet underneath it. I also want to have windows cut out and need a nest box added to the back. The one on display in my store seemed to be solidly constructed. On another post mentioned a removable pan for the bottom. Does anyone have any ideas on how to do this? Would it be okay to do the Deep litter method over say a plywood or similar type wood floor, could I cover the wood with the heavy plastic from Walmart? I have another question regarding the DE White Washing. If I decide to whitewash the inside of the house, will I need to reapply it if the whole house needs to wash out? I am new to all of this and there is alot of good information on this board.
