Product Description

PetSafe Staywell 400 Magnetic Cat Flap – White | 4-Way Locking Cat Door

The PetSafe Staywell 400 Magnetic Cat Flap is a reliable and secure magnetic cat flap designed to give your cat the freedom to come and go while helping to keep unwanted neighbourhood cats outside. Using a magnetic collar key, the flap unlocks only for your authorised pet, providing greater security than a standard manual cat flap.

Finished in a clean white colour, the Staywell 400 features a 4-way locking system, weatherproof transparent flap and universal fitting for timber doors, uPVC panels, glass and wall installations.

Magnetic Collar Key Entry

The Staywell 400 operates using the supplied silver magnetic collar key. When your cat approaches the flap, the magnetic key releases the locking mechanism, allowing your pet to enter while helping prevent access by neighbouring cats and other unwanted animals.

Unlike a standard cat flap, the magnetic locking system offers additional security without requiring batteries or electronic programming.

Secure 4-Way Locking System

Take complete control over your cat's movements with the easy-to-use four-position locking system.

  • Unlocked – Free entry and exit.
  • Locked – Prevents access in both directions.
  • In Only – Allows your cat to enter but not leave.
  • Out Only – Allows your cat to leave but prevents re-entry.

This makes it easy to keep your cat indoors overnight or restrict outdoor access whenever needed.

Suitable for Doors, Glass & Walls

The PetSafe Staywell 400 is suitable for installation into:

  • Wooden doors
  • uPVC panel doors
  • PVC and metal doors
  • Single-glazed glass
  • Replacement double-glazed units
  • Brick wall installations using optional tunnel extensions

Its universal fitting design allows installation into doors up to approximately 54mm thick.
