Overview
An interior cat door cut into a cat-shaped opening, sized to fit inside an existing door so cats up to 21 pounds can move between rooms while the door itself stays shut. Made from white ABS plastic by fatdaa, model FT01556.
The point of an interior door insert like this is usually to seal off a litter box, food bowls or a spare room from other pets while still letting the cat through on its own. Because it fits into the door rather than clipping onto it, the mounting hole has to match the panel size, and the door thickness needs to sit between 1.3 and 2 inches for the frame to seat properly.
- Cat-shaped cutout sized for pets up to 21 lbs
- Fits interior doors 1.3 to 2 inches thick
- White ABS plastic frame, 10.62 x 8.85 inches
- Made by fatdaa, model FT01556
Who it's for
Households that want to close off a room, most often to hide a litter box or keep dogs out of a food station, while still giving a cat free access. It is sized for cats and small pets up to 21 pounds, not for larger dogs.
Strengths and trade-offs
Drawn from this product's published specifications.
- Keeps a room closed to people or bigger pets while a cat passes freely
- Compact footprint at 10.62 by 8.85 inches
- Simple white ABS frame blends with most doors
- Requires cutting into the actual door, not a drop-in accessory
- Only fits doors 1.3 to 2 inches thick
- 21 lb weight cap rules out larger cats and dogs
Performance notes
Installation means cutting a matching opening into the door itself and fitting the ABS frame around it, so it is closer to installing a pet door than attaching an add-on flap. The frame ships in one size, 10.62 by 8.85 inches, and one color, white.
