Quick Summary
The PetSafe Magnetic Collar Key is a cat-access accessory for use with compatible PetSafe magnetic cat flaps in the 400 and 900 Series. It is supplied with an elastic strap designed for cats, and the magnetic key can be detached from the strap if needed.
This is a practical option when more than one cat needs access, as each cat can have its own key. If you are choosing this for a specific flap, the main check is compatibility with the 400 or 900 Series.
