Petsafe Staywell Tunnel Extention

The PetSafe Microchip Cat Door Tunnel Extension allows the PetSafe Microchip Cat Door to be installed into thicker doors or walls, adding 5 cm to the overall depth with each tunnel. Adding the tunnel is simple, with no tools required, and each extension can be secured in to place with glue for a flush, precise fit. Multiple tunnels can be used in order to fit the needed door or wall thickness. Your pet deserves the best.
