The Karlie Cat Doors Porta make the life of outdoor cats and their owners easier. 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 2-way lock offers the choice between open (out and in) and closed. The door is available in white and brown.
