We put this together but we were unsure of the cats using it. But we ended up placing it in the basement where we have a litter box down there to keep our new furnace from getting marked by one of the cats. Again if they do use it, probably only when needed or especially once winter comes and the porch litter box isn’t available. We have 3 litter boxes in total being used. We also took off the divider and the doors in case they felt claustrophobic.
