Best Cat Door Ever - Top 14 Topicks 2022

The width and height of the flap are closer in size than it is for dog doors, creating a square-shaped opening. Cats have an easier time maneuvering through smaller openings, so this is generally no issue for them. However, if your cat is particularly large, this smaller flap can get tricky.

Pet doors seem like a win-win, offering our fur babies the comfort and freedom to go outside when they need, while freeing us from needing to open the door every time they start whining. But pet doors aren't without their drawbacks—namely, the security risk they pose from burglars and even wild animal visitors.

A pet door or pet flap (also referred to in more specific terms, such as cat flap, cat door, dog flap, dog door, or doggy/doggie door) is a small opening to allow pets to enter and exit a building on their own without needing a human to open the door. Originally simple holes, the modern form is a hinged and often spring-loaded panel or flexible flap, and some are electronically controlled. They offer a degree of protection against wind, rain, and larger-bodied intruders entering the dwelling. Similar hatches can let dogs through fences at stiles. A related concept is the pet gate, which is easy for humans to open but acts as a secure pet barrier.

Automatic or electronic cat doors require the cat to wear a key to activate the system to unlock the door, allowing the cat to push the door with its head or nose and enter the house. The pet door needs to be programmed by registering the cat's tag or microchip in its memory.

Luckily, you can find plenty of cat doors made for cold weather—ones that are insulated and seal incredibly well. There are a lot of these cat doors for cold weather out there, though, so finding the best one can be time-consuming.
