【4 Rotating Locks】: Our indoor/outdoor cat door can be set to 4 modes using the rotating lock with tabs: exit only, entry only, both entry and exit, and fully locked, giving you easy control over your pet's comings and goings. 【Size】: Exterior dimensions 23.5*27*5.5cm (L x W x H), Interior dimensions: 18*19.5cm (L x W), suitable for installation on thin doors and walls, suitable for cats weighing less than 13kg. 【Quiet】: With the help of magnets and brushes, the panel does not make direct contact with the plastic, which reduces noise caused by large cats going in and out. The transparent door panel allows pets to observe their surroundings at all times. 【Reduce Your Heating and Air Conditioning Costs】The doors can't be left open all the time, allowing your cat to come and go freely without the heat in your home getting cold. 【Easy to Clean】The smooth plastic casing makes it easy to wipe away stains brought in by your cat from outside. Note: It's best used indoors.
