The Best Pet Doors for Windows
Pet doors for windows provide the convenience and freedom of a pet door without the hassle of installing through a door or wall. There are lots of options when it comes to installing a window pet door depending on your window style, insulation preferences, and pet size. We’re going to break down some of the best pet doors for windows so you can decide which is best for your home.
Pet Doors for Side-Sliding Windows
Installing a pet door in a sideways sliding window is quick and easy and allows your pet outdoor access directly from any window in your home. We carry a number of panels with built-in pet doors that install directly into the window track such that the slider side closes into the panel.
For severe weather, we recommend the Endura Flap Cat Door for Horizontal Sliding Windows. It withstands temperatures as low as -40 degrees Fahrenheit and stays shut in winds up to 50 mph. A high-quality pet door is excellent for keeping your home insulated to lower your energy bill. The Endura Flap Window Pet Door comes with a secure locking cover to block access to the flap when needed.
A great low-cost option is the Whiskers & Windows Cat Door for Horizontal Sliding Windows. Whereas the Endura Flap Window Cat Door has a flexible polyolefin polymer flap, the Whiskers & Windows Cat Door has a rigid plastic flap. Some cats prefer this flap style, which is nice and lightweight. Check out this article on training your cat to use a cat door for more tips.
Pet Doors for Sash Windows
Similar to the side-sliding window panel, a sash window pet door panel installs into the window track, no tools are needed. For the sash window insert, you would open up your sash window to the height of the panel such that they close against each other.
For harsh climates, we recommend the Endura Flap Thermo Sash Pet Door. The dual-pane glass and insulating pet door flap keeps your heating and AC inside year-round. Just like the side-sliding window panel, the Thermo Sash has a spring-loaded top piece that allows for quick, tool-free installation into window tracks of all heights. It is available in flap sizes from small to extra-large to fit pets of all sizes.
A great budget-friendly sash window pet door is the Dragon Sash Window Pet Door. The lightweight flap is easy for pets of all sizes to use and the two-piece flap design creates a complete seal over the opening for excellent insulation in mild climates. Check out the Dragon Double Flap Sash Window Pet Door for harsher climates.
For extra-large pets, the Hale Omni Sash is a great option. The giant flap size is 15 1/2" w x 27 1/2" h to fit extra-large dog breeds, yet the flap is lightweight enough that they can share the door with smaller pets.

Electronic Pet Doors for Windows
Electronic pet doors are perfect for keeping unwanted critters out of your home. An electronic window pet door is a great option for enjoying the benefits of an electronic pet door as well as the simple installation of a window pet door. Learn more about manual vs. electronic pet doors here.
Our top electronic window pet door pick is the Thermo Sash 2e with SureFlap Microchip Pet Door. The SureFlap pet door scans for your pet’s embedded microchip to unlock and allow access. This keeps neighborhood strays and wildlife out of your home for peace of mind. For pets who are not yet microchipped, the SureFlap Microchip Thermo Sash comes with an RFID collar key to operate the door.
To sum up, window pet doors are a great option for a low-hassle installation. They’re great for vacation homes and rentals as you do not need to make any alterations to a door or wall. Our selection of window pet doors generally come with a clamp lock to secure the panel in place in your track, and a Charley Bar can be installed for additional security.
