You may have heard of dog doors, but cat doors exist as well. Compared to dog doors, a kitty door is smaller and has a special cat flap that isn’t too heavy for them to move.
There are a variety of doors to choose from, including automatic cat doors, a window cat door, a microchip cat door, and even an interior cat door.
It’s important to consider what kind of space you have to offer, so if you need a cat door for a window or a cat door for sliding glass, there’s an option for each. Here are some of our top picks for the best cat door.
