Abstract: A new and improved cat outhouse provides for a cleaner and healthier way to care for an indoor cat. The cat outhouse attaches to the exterior of a house and comprises a box-like shelter, a litter pan, and at least one pass-through door so that the cat can enter the litter box from the inside of the house. The outhouse also has a ventilation system which helps to dissipate the smell and dust. Although regular changing of the cat litter is still necessary, the job is much easier and cleaner with the new invention. The cat pan can be removed from a slidable drawer at the bottom of the shelter, or in alternate embodiments, through the top opening of the shelter.
