Each condo is covered with a piece of tempered glass to give your cat a great view of the room and outside windows, while preventing interaction between unfamiliar boarders. All condos are individually ventilated 24 hours a day which even further minimizes the spread of air-borne illnesses. Condos can be opened to adjacent units to accommodate multi-cat families or if you just want to provide your cat with additional room during his or her visit. Eight of the twelve condos have a separate compartment for your pet's litter box and we still continue to provide our TLC program.
