Give your cat a key to your home! The PetSafe Microchip Cat Door reads your cat's unique 15-digit microchip ID and allows access to the programmed pet while restricting the entry of unwanted animals. This cat door programs up to 40 pets, making it ideal for multi-pet households. Programming your pet's microchip is as simple as pressing a button. The manual 4-way lock offers control over your cat's access, allowing you to secure it at night to keep your kitty safe inside. You can set it to 'Locked', 'Unlocked', 'Enter Only', or 'Exit Only'. The door is powered by 4 AA alkaline batteries and includes a low battery indicator. This PetSafe Microchip Cat Flap offers your cat easy access in and out of the house, without allowing neighbour’s pets, strange animals or wildlife to enter. The battery-operated flap allows registration of up to 40 microchipped cats, each weighing up to 8kg, without the need for a separate collar or tag. Programming the microchip numbers is both simple and quick. The four manual closure options are easily adjusted using a knob, allowing you to decide whether the pet flap should be completely closed, open in both directions, or open in only one direction. Thanks to the strengthened double locking, the robust PetSafe Microchip Cat Flap remains securely closed. The strong magnetic wind stopper and the draught excluder made from insulating fleece help to minimise the flow of cold air into your home. The PetSafe Microchip Cat Flap can be fitted into any doors or walls made from wood, PVC UPVC, metal, brick or glass, up to a thickness of 5cm. With the PetSafe Microchip Cat Flap, you are offering your cat the freedom and mobility it deserves! The flap can be fitted into rectangular doorways (17.1 x 18cm) or round glass openings (diameter 21.2cm). Installation is made easy with the included Quick Start Guide and cutout template. Additional tunnel extensions are available for fitting into thicker walls or doors.
