Overview
The PetSafe Never Rust Indoor Cat Door mounts into an interior door to give cats access to a room, food or litter box that stays closed off to dogs, using a magnetic closure and a plastic frame rated for cats up to 20 lb.
This is an interior door insert, not an exterior pet door, and it's built for doors up to 1.5 inches thick. The magnetic closure and white plastic frame keep the mechanism simple, and PetSafe includes paintable finishing plugs and screws for installation. It's sized around the cat using it, with the extra small dog breed size note in the specs describing the cat's own size class rather than dog access.
- Magnetic closure, white plastic frame
- Fits interior doors up to 1.5 inches thick
- Rated for cats up to 20 lb
- Made in USA, 1 year limited warranty
Who it's for
Households with a dog that needs to be kept out of a cat's litter box, food or private space, where an interior door already separates the rooms. Not for exterior walls or doors thicker than 1.5 inches.
Strengths and trade-offs
Drawn from this product's published specifications.
- Keeps dogs out of litter box or food while cats pass freely
- Magnetic closure adds privacy over an open cutout
- Includes finishing plugs and screws for install
- Backed by a 1 year limited warranty
- Only fits interior doors up to 1.5 inches thick
- Rated to 20 lb, not suited to larger cats
Performance notes
The magnetic closure is meant to swing shut on its own after the cat passes through, keeping the opening from staying propped open. Because the frame is rated to a 1.5 inch door thickness and a 20 lb cat, both limits are worth checking against the actual door and cat before installing.
