The Kitty Korner Slidelock hinge is patented and designed to convert a standard interior door into a cat door with a locking option in both open and closed positions. The mechanism slides upward and away from the floor, preventing floor strikes and enabling a smooth swing. This door is particularly suited for hollow-core doors and narrow door frames, offering reliable control over your cat’s access without a traditional flap.

This no-flap cat door emphasizes safety and creature comfort, using high-quality ABS material and a wide, smooth opening to prevent tail snagging. Its slim profile makes it suitable for hollow-core doors and thin walls. The interior door design minimizes dirt transfer to living spaces and prevents larger pets from entering, while providing clear access for cats up to 21 lbs.
CEESC Extra Large Cat Door – 4-Way Lock
The CEESC cat door features four locking modes (out only, in only, both, and fully locked) controlled by red and green switches. Outer dimensions are 9.8″ x 11″ with a 2.15″ depth, and the inner opening measures 7.9″ x 8.7″. It is designed to fit hollow walls and doors, suitable for pets up to 25.54 lbs. A transparent flap and rain seal contribute to visibility and weather protection, while a brush strip reduces noise from closing.
