The microchip cat flap for up to 9 cats features a 4-way locking control. Access for foreign animals is made impossible through the personal microchip or the CatMate brand. The LCD display shows the selected entry and exit lock status, as well as the location and time since the last flap activation for up to 3 cats. The integrated timer function controls access for all your cats (e.g., curfew at night). It comes with a self-covering feature for installation depths of up to 100 mm, making it suitable for single or double glazing and all panels up to a thickness of 100 mm. Additionally, the flap has a fully draft-proof and weatherproof brush seal. A tunnel is available for wall installation. The cat flap requires 4 AA batteries for operation, which are not included. The flap has a typical operational lifespan of approximately 12 months.
