Allow your cat free access: This cat door is designed for pet-owning families. It ensures your cat can freely enter and exit the room, keeps dogs away from litter boxes and food bowls, and provides your cat with a private space. Adjustable cat door: The cat door has 5 adjustable holes, allowing you to adjust the width to suit your cat's size. The adjustable width is 6.5-15 cm, suitable for cats of all sizes to enter and exit the room, while larger cats can remain outside. Sturdy and easy to use: This cat door is made of PE and stainless steel and can withstand the impact of large dogs. Our cat door can be opened with one hand and is easy to open from both the inside and outside. Easy installation: Simply tighten the tail screw and insert it into the door frame strike plate. The cat door will then work properly. Therefore, you do not need to replace the door frame strike plate or saw open the door panel, and you will not damage the door. Safety first: When not in use, the cat door bracket can be hung on the doorknob to prevent the door from hitting the door. Active children like to run around in the room, and any protruding foreign objects can pose a danger.
