Give your cat a door that’s just her size. The PetSafe® Interior 2-Way Locking Cat Door gives your furry friend private access to her own personal spaces. Even when the human door is closed, give your cat unlimited access to her litter box or food (while keeping your dog out). The transparent flap allows your cat to see her litter box or food on the other side of the door, making training and acclimation stress-free. 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.
