Cat Door for Interior Doors with Locking Knob and Flapless Entry

A Little Door for Cat Adventures

Cats often move between rooms for feeding areas, litter spaces, and quiet rest spots. This interior cat door creates a small passage through a standard door so cats can move between rooms without the door being fully open. The rounded gnome-style design features a flapless entry and a small window detail, turning a regular door into a recognizable pathway for daily routines around the home.

Built Like a Vintage Doorway

The door frame is made from ABS plastic and shaped with a rounded arch structure that resembles a small decorative vintage doorway. The exterior frame measures 11.5 in wide and 10 in high, with an interior opening about 8.5 in across for cats to pass through. Two frame panels mount on both sides of the door cutout and fixed together with screws and caps, forming a stable structure once installed.

Fits into Everyday Home Routines

After installation, the opening allows cats to pass between spaces such as bathrooms, laundry rooms, closets, or bedrooms where litter boxes or food stations are placed. The flapless design leaves the passage open, while the turning knob can close the doorway when access between rooms is not needed. The ABS surface can be wiped clean with a cloth, keeping the door frame neat during regular household use.
