PetSafe Microchip Cat Door – 4-Way Lock, Weatherproof, DIY Install for Up to 40 Pets

Freedom, security, and flexible setup for multi-pet homes

Your cat's microchip acts as her key, and the PetSafe Microchip Cat Door reads her unique 15-digit ID to grant entry only to programmed pets. This creates a sheltered pathway that supports the cats you trust while minimizing access for others. If you have a cat without a microchip, a programmable collar key can be used as a supplementary option.

Designed with independence and safety in mind, the door supports up to 40 programmed pets. A built-in 4-way lock lets you choose from Locked, Unlocked, Enter Only, or Exit Only to suit daily routines and privacy needs. Battery power ensures operation even when outlets aren’t nearby, and a low-battery alert helps prevent surprises.

In use, the door manages weather so outdoor weather doesn’t creep inside. Two magnetic latches act as a deterrent to stray paws, while the integrated weather stripping helps reduce drafts around the doorway. The door reads all FDX-B microchips, offering broad compatibility and long-term reliability.

Installation is designed for versatility. It fits most wood, PVC, and uPVC doors. For metal, glass, brick, or wall installations, additional accessories are sold separately. U.S.-based PetSafe support is ready by phone, email, or chat should you have questions during setup or daily use. Since 1998, PetSafe has focused on pet health, safety, and happiness through innovative products.
