Give your cats the best of both worlds with the white microchip cat flap. This thoughtfully designed cat door from Closer Pets operates with your cats' implanted microchips or a personalized Pet Mate I.D. tag. This allows your cats to go outside at their leisure and then comfortably settle back in their favorite spot at home. The flap can be programmed for up to 30 cats, making it ideal for a household with many kittens. It is incredibly easy to program with a simple click. You can also restrict access for individual cats. If you want all the cats to stay indoors overnight, you can completely lock the flap. The sleek design maximizes the passage space for your cat and ensures easy, stress-free access.
