Product Details


The Whiskers and Windows Horizontal Cat Door for Windows is a fast, affordable way to install a pet door in your home. This window insert requires no drilling or cutting (can be trimmed 3/4" shorter with a metal cutting blade if needed) and can be installed in seconds. Our spring-loaded design allows for instant adjustment of up to 3 inches and creates a snug weather-tight fit. This pet door comes in white and black color options, to match your window framing. For increased insulation you can purchase foam weather stripping to seal where the window frame and pet door meet.  Great for cats and very small dogs, this pet door will give you and your pets the freedom to come and go as you please. A four-way lock is included to provide security and access control. Simply use the red and green locking tabs to close it so nothing can enter or exit, allow access in and out, allow the pet to come in only at a certain time, or out only so they can't come back in until you allow it.

Locking the Flap

  • To change the 4-Way Lock setting, ensure that the flap is in the vertical resting position, and gently move the tabs left or right as desired. The tabs should move freely without requiring excessive force.
  • Locked: Both tabs on the outside.
  • Out-only: Both tabs to the right.
  • In-only: Both tabs to the left.
  • Unlocked: Both tabs in the center.

What if there is a gap between the panel and my window?

  • Due to the fact that there are many types of windows, you may need to modify your installation using shims or similar materials such as foam weather stripping.
  • If there is a gap, you can use the shims to even out the pet door.

Locking the Panel

  • A great way to lock your sliding window is a Charley bar or dowel in the track.
  • Both work off the same concept—they block the slider from opening. When engaged you cannot pull the sliding door away from the pet door panel.

FREQUENTLY ASKED QUESTIONS

What if my panel is slightly too tall?

You can trim up to 3/4” off the spring- loaded adjustment piece at the top. This can be done by removing the adjustment pieces with a #2 Phillips head screwdriver and cutting down the flanges. Be careful not to cut too low or you will not be able to put the top back on.

where to trim adjustment pieces

What if my panel is slightly too short?

We offer height extensions that will add 3/4” to the top of the panel that you slide into the channel at the top. These are made from the same aluminum as the panel so you can match the color.

You can also make your own extension out of nominal 1” wood (which is 3/4” thick), such as a 1x3, if you need more than %" in height. Cut it to the same width as the panel and slide it into the channel at the top. Paint the wood to match your frame color. If the extension makes the panel feel unstable, you can secure it with screws.

Great and easy door!

The door looks and fits great in our window! We needed to cut off just a bit of the top ****** on one side in order to get it to seat in the window, but we knew it would be a tight fit in our case. Otherwise, we threw on some A/C foam around the sides and it's making a great seal! The cats learned to use it very quickly, and the magnetic door keeps itself closed when not in use. The only issue I would have is that it lets in more sound that I would expect around the door itself, but it's not enough to complain about.

Very expensive to return item beware!

When my kittens whiskers and his body rapidly outgrew the small flap to send it back cost $56. At UPS. I didnt save the original packaging as I had no reason to think I would need it. This cost should have been covered for the original price of product.

Does NOT fit 46" Window!

Great Cat door! SUPER EASY install IF it actually fits your window. My window is EXACTLY 46" But you need a little more room to actually get it in the window. So Disappointed. This manufacturer should have taken this into account.

So easy to install! Your cat will love it!!

This adjustable cat door window was quick and easy to install. We just had to saw off one inch to make it fit the basement window. The cat can now let herself out at night to prowl the backyard and do her business without waking us up. No more litter box mess when we are not at home and our house stays safe and secure.
