Top Picks Explained
Before diving into the details of our top picks, let’s take a moment to learn about the different types of cat doors and what to look for when shopping for each type.
Types of Cat Doors
1. Basic Cat Flaps or Portals
Whether they have a flap or not, these doors are united in their lack of a locking mechanism. Because you can’t lock them, they’re best suited for indoor use.
They’re popular as entryways to garages or built into litter box enclosures. If you get one in the right size, you can use it in a multiple-pet home to let your cat into certain rooms while keeping dogs out.
What to Look For:
If you have a large cat, avoid cat flaps with openings that sit too close to the floor. Some are designed with smaller cats in mind and will force your kitty to scoot through with her belly to the floor.
2. Locking Cat Doors
These are the most popular cat doors available. They tend to last the longest and have the greatest value in terms of function.
Most locking cat doors allow you to set the door at different positions between full out-and-back access and a completely locked door.
What to Look For:
The best locking cat doors are well-built for years of use and are easy for both pets and pet parents to use. Pay attention to sizing—many of these doors come in several sizes for small or large cats, so it’s important to choose one that works for your cat.
Make sure the door is compatible with the place you plan to install it as well. Confirm that it fits your area and that it’s safe to install the flap in your door or wall before you make the first cut.
3. Electronic Doors
Instead of relying on manual locks, electronic doors have sensors that connect to an ID tag or your cat’s microchip which acts as a key to the cat door. These doors are ideal for multi-cat homes where you want one of your cats to have outdoor access but want to keep another inside. They’re also great for keeping raccoons, feral cats, and other invaders out of the house.
The downside of electronic doors is that they’re reliant on fallible technology and batteries. If the batteries die and you’re not there to replace them, your cat could be locked out of the house.
What to Look For:
Read customer reviews—companies won’t tell you about glitchy hardware and short battery life, but reviewers will. Excellent customer support is always important, but it’s crucial when you’re buying a high-tech cat door. Look for companies with a reputation for excellent customer support and a good warranty.

Frequently Asked Questions
Where is the best place to put a cat flap?
When it comes to choosing a location for your cat door, it all depends on the number and location of exterior doors you have in your home. If you have a side entrance, this may be the best option to give your cat a more concealed entrance and exit. Otherwise, the back door is generally better than the front door, especially when it comes to keeping feral cats and other animals out.
How do you install a cat door in an interior door?
Installing a cat door on an interior door is no different than installing it on an exterior door. Make sure you choose a cat door compatible with the type of door you have then use the included cutting template to mark the door and cut out the hole.
Should I lock my cat flap at night?
Many cat doors come with multifunctional locking mechanisms that allow you to leave the cat door completely open, completely locked, or something in between. For your cat’s safety, it’s generally best to lock the cat door at night so your cat can’t get out. If your cat is already outside, however, you should not lock the door – your cat should never be barred from reentering the home. Once your cat is in, you may want to lock the cat door to keep out feral cats and other animals.
