I have to laugh at this topic. I have a 2800 sq.ft. house with 3/4 of it Hardwood (teak) and Porcelain floors. Neither of my little babies have ever had an accident on either surface! They manage to seek out the few carpeted rooms, the throw rugs, etc. Really cracks me up. Heaven forbid they relieve themselves on an "easy to clean" surface!
My babies are houstrained and for the most part really good. Their "accidents" always happen in the middle of the night. Don't know how to train them to wake me if they have to go. Any one with any ideas???
