Overview
An interior door insert that cuts a pass-through opening, 8.46 by 7.87 inches, so cats can reach a litter box kept behind a closed door, rated for cats up to 25 pounds.
Unlike a typical exterior pet door, this is designed to hide a litter box room from view while still letting cats pass through an interior door. The ABS plastic frame keeps installation to a single cut-in opening rather than a full door swap.
- 8.46 x 7.87 inch pass-through opening
- Rated for cats up to 25 pounds
- Black finish, size Large
- ABS plastic frame and door
Who it's for
Owners who want a litter box kept in a closet or spare room, out of sight and out of the rest of the house, while still letting cats through an interior door.
Strengths and trade-offs

Performance notes
