Overview
A cat owner fitting a flap into an exterior door, an interior door or a window gets a plastic NAMSAN door whose lock works in four positions. The listing also names wooden and metal doors as suitable.
A weatherproof frame and locking flap let it work on exterior doors as well as interior ones, and the opening suits kittens and small dogs. Cutout size, screws and templates are not in the listing.
Who it's for
A home where a cat or small dog needs its own way through a door or window. Owners of bigger pets, or doors outside the listed thickness, need a different door.
Pros and cons
- Four way locking flap
- Suits doors and windows
- Opening sized for kittens and small dogs
- Thickness figures conflict
- Color listed as brown and white
- Cutout size not listed
- Plastic frame, not metal
Performance notes
The four-way lock lets the owner control which directions the flap opens. Weatherproofing depends on the frame fitting snugly in the cutout and on the door thickness matching the stated range.
