All cat owners know the hardest part of having an inside cat is cleaning the litter box. No matter what litter you use there is always the constant odor, plus the constant mess in and around the around box to clean up.
My patented design will eliminate all of this because the litter box is now located outside the house.
A low voltage fan plus vents on the outside of the casa prevents odors from entering the house and it climate controls the Casa by drawing air from inside the house.
The inside section holds a cat door where your cat can enter the Casa to use the litter box, and itís left all outside. No more mess or odors in the house.
