Introduce your cat to the flap before it's put in place so that they get used to the size and shape. The flap should be opened and let your cat explore it from every angle. Make sure the cut-out is level and square. Mark the screw holes and align them with your cat flap opening. The distance between the edges should be equal. Preparation Installing a cat flap inside your home is beneficial for the health and well-being of your pet.
