A cat door offers your feline friend the ultimate freedom to explore the great outdoors (or just the backyard!) on their own terms — something that you know is so important to them. From simple flaps to high-tech, microchip-activated models, there’s a cat door designed for every home and every cat’s personality.
Giving your cat their own little door is awesome for their independence, but hold off on breaking out the tools just yet — there are a few things to think about first. Do you need a cat door without cutting the door for a rental property? Or perhaps a window cat door for vertical placement to avoid altering a wall or door? The size and breed of your cat will also influence your choice, ensuring they can comfortably and safely pass through.
We’ll take you through all the different kinds of cat doors out there, so you can pick the perfect one for your kitty and your place.

Increased Independence for Your Cat
Cats love having the freedom to explore, whether it’s moving between rooms or accessing the outdoors. A cat door lets them come and go on their terms.
Convenience for Pet Parents
No more constant door duty! Cat doors save you the trouble of opening doors repeatedly, especially during the night or when you’re busy.
Customizable Options for Every Home
From indoor cat doors to cat doors for windows to installing a cat door without cutting doors, there’s a solution for renters, homeowners, and unique spaces.
Encourages Physical Activity
Letting your cat explore the great outdoors (or even just another room) can really help them burn off energy and keep their minds sharp, which means less stress and boredom for them.
Improved Indoor Environment
With access to litter boxes in separate rooms or outdoor spaces, you can keep your home cleaner and more odor-free.
Energy Efficiency and Safety Features
Newer cat doors are packed with cool features like insulated flaps to keep the weather out, microchip readers to let only your cat in, and locks for extra security, so your house stays safe and cozy.
A Lifesaver for Multi-Cat Households
If you have multiple cats, a cat door can help reduce tension by allowing shy cats to retreat or giving adventurous ones more freedom.
Note: However, keep in mind that a poorly chosen or installed cat door could provide access for unwanted animals or even human intruders. It is very important to pick a safe model and then install it correctly.
How to Choose a Cat Door?
Choosing the perfect cat door involves considering several factors to ensure your cat’s safety, comfort, and your own peace of mind. Here’s a breakdown:
Consider Your Cat’s Size
This is crucial! Measure your cat from the top of their shoulders to the bottom of their chest to determine the appropriate flap height. They should be able to pass through comfortably without crouching too much or having to jump excessively. Also, ensure the flap opening is wide enough for them to pass through easily.
Think About Your Home’s Structure
- Door Installation: The most common option. Ensure your door is thick enough to accommodate the cat door’s tunnel.
- Wall Installation: A good option if you don’t want to modify a door, but it requires more extensive installation.
- Window or Patio Door Inserts: Ideal for renters or those who don’t want to cut into a door or wall. These inserts fit into existing window or sliding door tracks. A window cat door vertical design is a good option for this.
Choose the Right Type of Cat Door
- Basic Flap Doors: The simplest and most affordable option. They offer basic access but may not be the most energy-efficient or secure.
- Magnetic Cat Doors: Use a magnet on your cat’s collar to activate the flap, preventing access from other animals (but your cat needs to wear a collar).
- Microchip Cat Doors: These are the most secure, using your cat’s existing microchip to grant access. They prevent unwanted animals from entering and work well for homes with more than one pet.
- Electronic Cat Doors: Similar to microchip doors, but may use a key fob or other electronic device.
Think About Security
- Locking Mechanisms: Look for doors with secure locking mechanisms to prevent unwanted entry when needed.
- Durable Construction: Choose a door made from sturdy materials that can withstand weather and wear and tear.
Consider Weather Protection
- Weatherstripping: Look for doors with good weatherstripping to prevent drafts and leaks.
- Tunnel Length: If installing through a thick wall, ensure the tunnel is long enough to create a good seal.
Ease of Installation
Assess your own DIY skills. Some cat doors are easy to install, while others may require professional help.
Budget
Cat doors range in price from basic flaps to high-tech models. Determine your budget before you start shopping.

FAQ
What is the best type of cat flap?
The “best” cat flap depends on your needs. For security, microchip models are top-notch. For basic access, simple flap doors work fine. Consider your budget, cat’s size, and home setup to choose the right fit.
How much does it cost to put in a cat door?
The cost varies. Basic flaps can be under $20, while microchip models can exceed $100. Professional installation can add $50-$200 or more, depending on the complexity of the job. DIY installation is a cost-effective alternative.
Can you buy a door with a cat flap already installed?
Yes, you can find doors with pre-installed cat flaps. These are convenient options, especially if you’re replacing an existing door. However, they may offer less flexibility in terms of cat flap choice and placement.
What is the most efficient type of flap?
For weather protection and energy efficiency, look for flaps with good weather stripping, magnetic closures, and double-flap designs. With these features working hard to block drafts and seal out the weather, you can enjoy a more comfortable home and potentially lower energy bills.
Is a cat flap a good idea?
Cat flaps are awesome for letting your cat roam free and saving you tons of trips to the door. They’re especially great if you’re always on the go and help your cat stay active and independent.
What can I use instead of a cat flap?
If a cat flap isn’t suitable, consider creating a designated “cat zone” with food, water, and a litter box in a specific room, or using a baby gate to keep dogs out while allowing cat access over or through it.
How long does a cat flap last?
A well-made cat flap can last for many years, often 5-10 or more, depending on the quality of materials and how much it’s used. Regular cleaning and occasional replacement of worn parts like flaps or weatherstripping can extend its lifespan.
