Window Pet Doors

A cat or doggie door for windows usually takes just seconds to install; there's no cutting involved and many models require no tools at all.

A cat or doggy door in windows is a great solution for folks looking for a pet door for an apartment, or others looking for a temporary pet door solution, because there is no need to cut a hole in a door or wall. They are very popular for cats and small dogs; but we carry window doors for large dogs, too.

We carry more than 30 models of cat and dog doors for windows so there is a very good chance we have the size, color and style that will work well for a price range that works with your budget. You'll find the most popular and trusted brands of window pet doors at America's Pet Store including Hale, Ideal, PetSafe and Patio Pacific.

America's Pet Store carries a wide variety of cat and dog doors for windows, from basic models to others with special features such as tamper-proof locks or energy-efficient flaps. Whether you are looking to put a pet door in a vertical sash window (one that slides up and down) or a horizontal sliding window, you'll find window pet doors here for either case.

Although more commonly purchased as cat doors, we carry all sizes of pet doors for windows, not just small pet doors. You'll find several brands that are large enough to be used as window pet doors for dogs. Patio Pacific makes large window pet doors, Ideal makes what they call Super Large window pet doors (15" W x 20" H) and Hale Pet Doors for sash windows go all the way up to a Giant size with a pet flap that is 15 1/2" W x 27 1/2" H. Now that's a big doggy door for windows!

Please Note: If you are searching for large pet doors or XL pet doors for windows you may need a dog ramp to ensure easy access as well as your pet's safety. Or, if you have sliding glass doors, perhaps it's worth a look at some of our pet doors for sliders. Many models of pet doors for sliding glass doors are just as easy to install and remove as window pet doors.

Cat window doors and other pet doors for windows are available for both horizontal and vertical sash windows. The great thing about pet window doors is that they are, in most cases, temporary pet doors. So you can install them when you want your pet to use them and remove them when you are all through. Window pet doors are a great lower-cost alternative to pet doors for sliding glass doors.  If you want to use a pet door through a window, but can't find the right pet window door, take a look at our dog doors for screen doors. These pet doors can also be used through a window screen.

No matter what kind of pet door you might be looking for there is one thing that is true across the board for all of them: your pet must be able to fit through the flap opening. Believe it or not, it is one of the biggest reasons people return window pet doors: they didn't think to check the flap size before purchase and then they find that their pet can't fit through them!

Do yourself a favor and take note of the dimensions of the flap entrance on any pet door you buy, and then compare it to the size of your pet. No matter where window pet doors are purchased, from America's Pet Store or anywhere else, you'll save yourself potential hassle if you measure before you buy. It's not difficult and only takes a few minutes.

One way to be absolutely sure about the size is to cut out a hole in a piece of cardboard that is the same size as the flap entrance on the pet door you are considering. If your pet can fit through the cut-out hole in the cardboard, then the flap size on the actual window pet door will work, too.

If you have questions about window pet doors or how to be sure you are getting the right size for your pet, contact our customer service department toll-free at 1-800-870-1941, or via email at and one of our representatives will be happy to assist you.

In addition to window pet doors and pet doors for patio doors, America's Pet Store carries many other styles, including wall-mount pet doors and fully automatic pet doors. Electronic pet doors are popular with folks concerned with security. These doors will only open for pets wearing a collar key. They will not open for wild or feral animals, crawling infants or toddlers, or intruders. Among the most secure are Plexidor pet doors that use RFID technology. As a bonus, these products are inherently energy-efficient pet doors because they cannot blow open in the wind.

Other brands of electric pet doors carried by include High Tech Pet Power Pet Doors, PetSafe pet doors and Ideal Pet Doors.

Magnetic pet doors are also automatic and we carry the most popular brands: Staywell pet doors, Patio Pacific pet doors and DogWalk pet doors. Patio Pacific magnetic pet door models are only available in their lineup of patio pet doors. The DogWalk models are called CatWalk pet doors because they are quite small and suitable only as pet doors for cats and very small dogs such as toy breeds.

Another brand carried by America's Pet Store is Freedom Pet Pass pet doors. Please note that we no longer carry storm doors with pet doors. If that is what you are looking for, please give us a call so we can make some other suggestions that may work even better for you.
