【Only for Cats but Child and Dog Safe】Use this adjustable door latch to keep dogs and children out while providing an opening for cats to eat and relieve themselves freely without being disturbed by dogs and children. 【Sturdy and Durable】With a stainless steel chain, our cat door latch is more durable and sturdy than traditional straps. Even in the face of large and determined dogs, it can remain still. Premium EVA foam to resist door slams, pinching, and hard impacts. 【Easy to Use】Just press and hold the button on the right side of the latch and slide the middle slider up and down to easily close/open the lock, preventing children from unlocking the door themselves. It can also be adjusted by attaching a link to the latch chain, up to a width of 18 cm/7 inches. 【Easy Installation】The door latch is easy to install and can be attached to a door or door frame using the included adhesive at both ends. For added security, it can also be screwed into the wall to prevent pets and children from touching each other. If removing, we recommend placing the latch and door stop out of reach of children and pets. 【Suitable for Most Doors】Cat door latches and door stops are suitable for most door types, such as wood, iron, and glass doors, to adapt to the size of your cat and dog.
