The Best Cat Doors (Review) in 2020

Kicking off our list of the best cat doors is this pet flap for patios by PetSafe. Available in a variety of sizes, it’s the perfect fit for almost any sliding glass door. It’s easy to install and take away, making for an easy piece of kit to take with you when you move home. For this reason, PetSafe say their door is a particularly good solution for rental homes.

Once the door’s in place, your cat will be able to move in and out with ease. The flexible flap is held in place with a magnetic closure mechanism, and with just a little training kitties can work their way in and out to their heart’s desire. When closed, the flap creates a tight seal, allowing you to maintain an energy efficient home. Each pet door is made from a tough but lightweight aluminum frame and tempered glass, designed to last and look great doing it. If you need to keep your pet in – or out – of the house for a set time, you can also seal the flap to control access. With three subtle colors to choose from, the door blends easily with your interior, too, so it looks great in practically any room.

The next cat door to earn itself a spot on our list is this simple but effective choice by Ideal Pet Products. Made from durable, weather-proof Lexan plastic, it’s the perfect option for fickle climates. Thanks to its telescopic frame, the flap is easy to install in virtually any door, no matter how thick. In fact, the simple design can also be installed in windows.

With its felt lining, the flap helps prevent warm air from seeping out of your house. This creates an energy efficient seal without being too difficult for cats to push through. You can even lock the door when necessary, with a strong locking mechanism that keeps unwanted animals out.

Indoor kitties can also benefit from cat door installation. They may not be skittering in and out of the house itself, but when they want to move from room to room, and you want to keep your door shut, Cathole’s handy archway is a great solution. It’s great for keeping your cat’s litter box away from your living space, without impeding their access. The device also prevents any devious dogs or curious children from stumbling across the litter box and making an unhygienic mess.

The archway can be installed in as little as 30 minutes by just about anyone, even if you’re not especially DIY savvy. Made from Baltic birch wood, the archway is easy to paint, allowing it to blend in with any door. It also features a removable brush lining, designed to groom your cat as they pass through. The brush can be detached and replaced with a simple snap mechanism, for easy cleaning.

The Kitty Pass have also earned themselves a spot on our list, with this adorable yet practical interior cat door.  Featuring a cute ears and tail design, this diminutive archway is the perfect solution for cats who need freedom about the house. It can be installed in any wooden door, and won’t look out of place thanks to its simple, elegant appearance. If desired, you can paint the archway to better match your interior, or add a splash of color.

It’s the perfect way to keep litter boxes out of sight, without impeding your cat’s bathroom access. Most owners are able to install the door in 15 to 25 minutes, for an incredibly quick and easy set up. Customers report that this a-door-able cat archway is simple to put into action, looks great, and always elicits a giggle from guests. Each Kitty Pass product is manufactured to a high standard of quality in the USA.

For bigger breeds – such as Maine Coons and  Ragdolls – this large cat door is the perfect solution. It’s also suitable for small dog breeds, such as Yorkshire Terriers, Dachshunds, and Spaniels. Built a little bigger than your average flap, it offers your feline friend unimpeded access to their hunting ground. Thanks to its clever four way locking system, you can allow your cat in without letting them out again, or allow them out without letting them in again. This diverse set up makes it easy to take control of how long your cat spends out and about.

The door is surrounded by a brush strip, carefully designed to reduce energy loss from your home in the form of heat. These bristles also help the door to swing open and shut silently, so you’ll never be disturbed by noisy cats barrelling in and out of your house.

Purrfect Portals have also found a spot on our list, thanks to their unique interior cat door. It’s the purrfect way to provide cats with access to their food water, and litter box, while keeping dogs and small children at bay. This accommodating archway is perfect for medium and large cats, giving them plenty of clearance without being too big.

Its adorable, patent-pending design resembles a cat’s face – complete with ears and whiskers – so there’s no arguing over who it’s actually for. Unlike exterior cat doors, the Purrfect Portal doesn’t have a flap. This means it’s quiet to use, and won’t irritate your feline. Most cats require some training when it comes to using a flap, but they should traverse their new portal naturally. The easy to install archway is at home on any door, thanks to its subtle cream color.

If you’re looking for a solution that’s a little more high tech, look no further than this microchip cat flap by SureFlap. The electronic cat flap only opens for your cat, by reading their implanted ID microchip. This clever mechanism keeps strays and neighbor cats at bay, without restricting your feline’s movements. It can actually recognize up to 32 microchips, so it’s perfectly at home in multi-cat households. If your cat isn’t microchipped, there’s no need to worry – you can purchase a programmable collar tag separately.

The cat door is powered by normal household batteries – two AA cells. When your cat approaches, the device reads their microchip, and releases its lock automatically in response. Each pair of batteries can last up to 12 months, and a handy low-battery indicator will let you know when it’s time for a change. The door is versatile, too, suitable for almost any door or window. You can also lock the door when required, keeping kitties in out out.

PetSafe have earned themselves a second spot on our list, with their large cat flap. Suitable for pets weighing up to 25 pounds, it’s perfect for bigger cats and smaller dogs, giving them safe and easy access to the great outdoors. Made from strong, durable plastic, the door stands up well to regular use, even by heavier kitties. It’s weatherproof too, designed to withstand wind, rain, hail, or snow.

Thanks to the door’s four way locking system, pets can be kept in, or out, giving you control over your cat’s outdoor time. Its slim, sleek design looks great with any door, and windows too. The door comes with everything you’ll need for an easy installation. It also features an insulating felt seal, keeping heat energy inside your home.

The penultimate cat flap to make our list is this simple but effective design by Perfect Pet. The unique flap is made from a soft, flexible, plastic, ideal for cats who are a little nervous about pushing through a hard door. It also features a telescopic frame, for easy installation in doors and windows of all different thicknesses.

Thanks to the door’s tamper-proof mounting system, it can’t be removed from the outside. This neat feature prevents any would-be thieves from using the flap to break into your home, and keeps the door secure during use, too. Although it’s flexible, the flap itself is super soft, and impact resistant. It automatically falls back in place once your cat is safely in or out, making for a neat seal that helps prevent heat from escaping your home.

Last, but not least, is this medium sized cat flap by Depets. Featuring durable materials, a four way lock, and a transparent flap, it’s the perfect way to improve your cat’s access both in and outside the home. The transparent door encourages cats to push through the flap, by letting them see the room or world beyond before they venture through. Although it allows light through, the screen won’t let any water through, keeping your home warm and snug even during adverse weather.

The cat door also includes four different locking modes: it can be unlocked, totally locked, or locked from just the inside or outside. This handy mechanism gives owners optimal control over when and if their feline friend ventures outside. A felt-like lining around the flat itself helps to form a tight seal when it’s not in use, preventing heat from escaping your home, and saving energy in the process.
