These Are The Best Cat Doors

Cat doors are a popular solution for pet owners who want to give their feline free access from the inside to the outside—and back again.

These openings are typically smaller in size than a standard-size dog door and are equipped with a frame and flap that cats can easily fit through.

Even for indoor-only cats, a cat door can be a great way to give your kitty access to rooms where the door is frequently closed.

Choosing the best cat door begins with measuring your cat. Cat doors come in a variety of sizes, so choose one that will comfortably accommodate the largest cat using the door.

Keep in mind that most cat doors designed for exterior doors can also be used on interior doors, but this isn't always the case.

You'll also want to consider what kind of locking mechanism you'll need on your cat door to protect your pet and keep strange animals out of your home!

Here are the best cat doors for allowing your feline to roam freely that BestForPets (bestforpets.org) recommends.

Overall winner: Ideal Pet Products Cat Flap Door
 

This Ideal Pet Products cat door takes the top spot due to its simplicity, locking mechanisms, and low price.

This cat door, despite being a more basic model, can be used on both interior and exterior doors and has a four-way locking mechanism: in only, out only, open or locked closed. It also has a magnetic, self-closing flap to keep unwanted pests out of your home (including stray cats!).

This cat door is made of super durable Lexan polycarbonate and will withstand everyday use as well as harsher weather conditions. It’s also simple to install—the frame screws into any standard interior or exterior door.

The flap on this cat door measures 6.25″ by 6.25″ and is suitable for cats weighing less than 12 pounds. However, some cat owners report that their larger cats can easily use the door.

 

SureFlap Microchip Cat Flap is the best microchip
 

Looking for a more advanced option? SureFlap’s MicroChip Cat Flap is worth a look. Although it is the most expensive cat door on our list, it will provide your cat with safe entry and exit while keeping pests and strays out of your home. Instead of attaching a magnet or other access tool to your cat’s collar, this door uses your cat’s existing microchip.

This is how it works: To begin, press the “program” button on the door’s top and guide your cat through the tunnel. The door will read your cat’s current microchip and download the data.

The next time your cat tries to enter through the door, it will grant access based on the microchip data. It can remember up to 32(!) different cats and is compatible with 9-, 10-, and 15-digit microchips.

This cat door measures 8.2″ by 8.2″ and is suitable for small to large cats. It can be mounted on interior or exterior doors, windows, and walls using the appropriate mounting accessories.

 

Ani Mate Cat Mate Large Cat Door is the best large cat door
 

Cat Mate’s Large Cat Door is 8.25″ by 9″ in size and was designed specifically for large cats or small dogs. It is suitable for any size cat or small dog with a shoulder height of 13″ or less.

With the simple, do-it-yourself instructions and template provided, this cat door can be installed on any interior or exterior door, panel, or wall.

It has a rain-proof external frame seal as well as a weather-proof seal with a magnetic closure to keep the elements out. Customers in the real world adore this cat door. They praise it for its ease of installation, durability, and functionality.

 

The Kitty Pass Interior Cat Door is the best interior cat door
 

Not only is Kitty Pass’s Interior Cat Door adorable (look at those little ears! ), but it’s also the simplest way for your cat to gain access to closed interior doors.

Consider installing this pick if you want to hide your cat’s litter box or food, or if you’re tired of hearing her scratch your bedroom door at night.

The Kitty Pass is designed to fit all standard doors ranging in thickness from 1.25″ to 1.75″ and does not require any unsightly screws or hardware to be installed.

Although this cat door is finished in semi-gloss white, you can repaint it to match the colors in your home.

The tunnel is 7.5″ wide and 6.5″ tall, making it suitable for most cats, though the manufacturer recommends it for cats weighing 20 pounds or less. Furthermore, the opening is made of super smooth plastic, so your cat’s fur or tail will not snag.

 

CATHOLE Original CatHole Interior Pet Door is the best grooming product
 

CatHole’s Original Interior Pet Door can also be used to conceal a litter box or cat food behind interior doors or walls, but it also has a removable grooming brush to dust dirt and litter off your cat as he passes through the tunnel.

That means no more tracking loose litter around your home. This interior cat door is made of Baltic Birch wood (which you can paint to match your home’s décor) and is super easy to install with the included instructions and wood cutting template.

This cat door measures 8.5″ wide by 8.5″ tall and is intended for cats weighing no more than 20 pounds.

Warning: Some customers reported that their 20-pound cats had difficulty getting through this door, so it may be best for slightly smaller cats.

FAQ

How do I put in a cat door?

Most cat doors come with an installation template. You’ll also need the following materials in addition to the template:

  • Drill the hole with a 3/8-inch or 1/2-inch drill bit.
  • The jigsaw
  • Tape measure
  • Pencil

Begin by measuring the distance between your cat’s stomach and the floor. This is the approximate distance between the bottom of the cat door and the floor.

Take the door off its hinges and place it on two sawhorses.

Place the template on the door and use the measurement from Step 1 to determine the location of the cat door’s bottom. Remember that the opening you make should be at least 3 inches from any of the door’s edges.

To keep the template in place, trace around it with a pencil and/or use tape.

Make a hole in each corner of the template with the drill. Remember that if you have a metal door (common for exterior doors), you’ll need to use a drill bit designed specifically for this material.

Starting in one hole, use the jig saw to make a straight cut from one corner to the next, as closely as possible following the template. Repeat until the opening for the cat door is complete. (As with the drill bit, if cutting a metal door, use a jig saw blade designed for use on metal.)

Finally, insert the interior and exterior sides of the cat door frame if you’re using a self-framing cat door. Attach using the included hardware in the manner specified. If you are not using a self-framing door, you will need to cut four pieces of wood to fit the dimensions of your door, attach them to make a frame, and install this before you can install the cat door.

What should I do with my cat door?

Install a cat door in a location where your cat will have easy access to a frequently visited area. An exterior door is a common location for a cat flap for cats who spend time both indoors and outdoors.

However, a cat door can also be used on interior doors to allow your cat easy access to the litter box or food bowls.

Many homeowners choose this option when they want to keep their cat’s litter box or food bowls in a laundry room, bathroom, or bedroom but don’t want to leave the door open all the time.

Final Decision

Ideal Pet Products Cat Flap Door is our top pick for a cat door. This option is simple to install and can be used on either an interior or exterior door.

It has a polycarbonate flap and a four-way locking mechanism, which many cat owners consider essential. Large Cat Door by Cat Mate is a more basic option.

This low-cost cat door is less expensive, and the locking mechanism is more difficult to use, but it can still be installed on any standard interior or exterior door.
