The access and exit are controlled by an electronic ID (2 IDs included) for up to 9 cats, keeping other animals away. An LCD display shows the selected access and the status of the entry, as well as location and time details since the last activation of the flap for up to 3 cats. A battery status indicator is also included. The device requires 4 AA batteries (not included). A timer function controls access for all your cats and allows you to prevent exit at night. It features a self-trimming design for mounting depths of up to 50 mm, making it suitable for single and double glazing as well as all panels up to a thickness of 50 mm. A tunnel for wall mounting is available. The flap includes draft-proof, weather-resistant brush seals.
