A cat flap-style door lets your pet leave the house and return inside without needing to open the doors for them. They are available in varying sizes to accommodate dogs and cats and also have features that can prevent draughts or unwanted critters. Introduce your pet to the door prior to installing it. It will be easier to get them used to the shape, size and motion. Easy to install Cat flaps can be put up everywhere - you can have one in your garage or laundry room, to allow your pets access to cat food and litter box and even on your bedroom door
