We have 4 of the rascals and they are big boys (neutered). Regular litter
boxes were too small so we experimented with plastic storage containers.
They are 15"x21"x5" and work pretty well but could be better. My wife has
suggested the plastic under bed storage containers. They are 20"x39"x6". We
have plenty of room as the boxes are in the basement. Anyone have any
thoughts or better solutions?
