Overview

An interior cat door from Purrfect Portal sold under the Gnome Door name, sized for cats up to 20 pounds. It skips the swinging flap in favor of a lockable, no-flap design meant to fit into standard interior doors.

The listing describes it as a no-flap design, which trades the draft and noise of a swinging flap for an open passage that locks shut when needed. At roughly 9.25 by 10.83 inches, this is sized for interior door cutouts, not exterior doors.

  • Lockable, no-flap design for interior doors
  • Rated for pets up to 20 pounds
  • Acrylonitrile butadiene styrene (ABS) plastic construction
  • Sized at roughly 9.25 x 10.83 inches

Who it's for

Fits owners who want to give a cat access to one room while keeping other pets or people out, using a lockable interior cutout instead of a flap. The 20 pound weight limit and medium dog breed size note suggest it can also work for small dogs, but it is built around cat use.

Pros and cons

Pros
  • Lockable, so access can be closed off on demand
  • No-flap design avoids flap noise and swinging resistance
  • Sized for cats and small dogs up to 20 lbs
Cons
  • No flap means no barrier against drafts when unlocked
  • Built for interior doors, not exterior use
  • ABS plastic frame rather than a heavier duty material

Performance notes

Because it has no flap, the opening stays clear rather than swinging, which removes flap noise but also means there is nothing blocking drafts or sightlines when unlocked. The lock is the main access control, letting owners close it off on demand for cats and small dogs up to 20 pounds.
