Product Details


The Whiskers and Windows Horizontal Cat flap door for Windows is a fast, hassle-free, affordable way to install a pet door for cats in your home. This aluminum sash 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 pet door insert design allows for instant adjustment of up to 3 inches and creates a snug weather-tight fit. This sash window cat door comes in white and black color options, to match your window framing. Great for cats and very small dogs, this dog door will give you and your pets the freedom to come and go as you please. The four-way locking cat flap 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. 

Features:

  • Great for renters with no-tool installation
  • Adjustment ranges fit most windows and custom options can be made, however, they are non-returnable
  • Small can fit cats up to 10Lbs and the Large is good for cats and small dogs up to 15Lbs
  • Easy to install
  • Lightweight flap is easy to use
  • Flap is lockable 4-ways ( Unlocked both tabs center | Locked both tabs outside | Out-only both tabs to right | In-only both tabs to left )
  • Allow 3-4 weeks for any custom options

Step 1 Release Spring Mechanism

Step 2 Insert Into Window Track

  • Open the sliding window and insert the cat door panel with the knobs facing inside. Place the top edge into the top track of the window.
  • Lift up and swing the lower portion of the panel into the bottom track.
  • Slide the pet door panel against the window jamb. Make sure that the top is fully extended (not tilted to one side) and the bottom of the panel is on the ridge (pencil rail) in the bottom track.

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.

The dark area marks where you can trim:

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.

FAQ

How big of a dog can go through this?

The large cat door flap would accommodate a dog about 15Lbs, and no more than 10" at the shoulder.

Can you lock it?

Yes, this cat door window insert has a 4-way lock which means you have 4 different access options. You can set it for totally locked, so nothing can go in or out. Open, so they can go in and out as they please. In only, so that once they come in they can't go back out until you let them. Or out only, so once the exit they will need you to let them back in.

Is the doggy flap see through?

There is a slight tint, but you can see through it.

Is it hard for really small pets to use?

The flap is very easy to push open so small pets have no trouble using it. It is rigid though, so if your pet is timid we would recommend the Petsafe Horizontal Cat door for Windows.

Could this be used leading out to a catio?

Yes! In fact that is one of the more popular reasons customers get these doors.

How can I control which pet can use the door?

You will need to get an electronic pet door. The Sureflap microchip cat flap can detect the unique serial number on your cat’s microchip to lock and unlock the door. While not a microchip pet door, the Cat mate is just as effective as it uses collar tags as a “key” for your cats.

Window arrived quickly despite custom measurements. It was well packaged for shipping and arrived with no damage. Installed in seconds. We did add weatherstripping from our local hardware store to prevent movement and seal out bugs/ drafts. Overall very pleased and recommend the product!

I like the door it was exactly what I wanted. It works very well in the small window opening. My cat took a few days to get used to it, but now she uses it all the time. Thank you for making this custom very small cat door insert.
