Cat Door Alternative: We have improved the cat door to meet market challenges. New integrated fisheye design, made of environmentally friendly materials and odorless. It is designed to be more durable, flexible, and less prone to damage than standard products. Only let cats in: The pet door easily hooks onto most door handles and securely holds the door, protecting your cat's private space from larger animals! It can withstand impacts from large pets. Easy to install and use: Install the cat door attachment; no tools or glue required, and no modifications to the door are needed. It will not ruin your paint or damage your home! It only takes two steps to let your pet enjoy an independent private space: hang it on the door handle and then connect it to the door frame's latch slot. Convenient design: The ingenious design makes it easy to open the door with just one hand, from inside or outside the room when you are tired or carrying heavy items, while keeping small children away from the cat's room. 5 adjustable sizes: 5 functional holes allow the door latch to be opened for cats (from 6.5 cm to 15 cm), and the opening is wide enough for cats to easily enter, while being narrow enough so that dogs and infants cannot get through. You no longer need to confine your cat to a cramped cage; it is the perfect solution for your cat to have privacy. The best choice for pet owners: try our pet door latch. Effectively prevents crawling infants, toddlers, large dogs, and puppies from entering unwanted and unsafe areas, such as the laundry room, bathroom, closet, bedroom, pantry, or office. You can also travel anywhere with you and your pets! We will be your favorite travel accessory!
