4-WAY LOCKING CAT DOOR
This durable, transparent PetSafe flap lets cats come and go from the room where their litter box is housed, even when the door is closed. The high-impact plastic frame is easily installed in any interior door that is 1" to 2", or 2.5 cm to 5 cm thick. The 4-way locking system gives owners the ultimate control on the kind of access they wish to give pets. It is suitable for dogs and cats up to 15 pounds.
