This 4-way cat flap with tunnel elements from TRIXIE allows your pet to enter or exit the house independently – even with the door closed. Cats often change their minds about where they want to be several times a day. Therefore, you may not always feel like opening the door for your pet. In this case, the cat flap can be very useful. This cat flap features a transparent flap and operates silently. The cat door has 4 modes: open in both directions, closed in both directions, open only for exiting, and open only for entering. The surrounding 360° seal and the rotary lock help prevent drafts. The 2 tunnel elements are designed for walls and thick doors. You can also purchase additional tunnel elements to extend the cat flap even further.
