The Karlie Porta cat doors make life easier for outdoor cats and their owners. They consist of a frame, a hinge and a horizontally mounted flap. The latter is pushed forward by the animal with its head in order to then get through the opening. In this way, the cat can switch independently and safely between the house and outside. A magnetic lock and a brush seal make the cat door weatherproof and draft-proof. Thanks to the locking system, it can also be controlled whether the cat can go in and out at will or whether its use is restricted. The mechanical cat door with 4-way lock offers the choice between open (out and in) and closed as well as the options only in and only out. The door is available in white and brown and has a tunnel element (50 mm) for covering the passage.
