Give your cat a door that’s just their size. The PetSafe Interior 2-Way Locking Cat Door gives your furry friend private access to their own personal spaces. Even when the human door is closed, give your cat unlimited access to their litter box or food (while keeping your dog out). The pet door has a lock on the bottom, so you can control your pet’s access into the room if needed. Installing your new pet door is an easy DIY project and the pet door fits most interior doors 1/2- 2 inches thick. Your pet deserves the best. Trust PetSafe to help keep your pet healthy, safe and happy.
