Within another day, all 13 kittens will be together, running free in the two rooms. They are totally litter trained now, but if an accident does occur, it is easy to clean up on the tile floors. They won't be trusted on the living room carpet for at least another week. This stage in potty training is very important: allowing mistakes to happen is such a backwards step. Now is the time to instill in their minds exactly where this duty must be done. Only then will their life's adventure expand into other rooms of the house.
