Features

  • Custom Fit For Your Specific Window - Custom cut to ensure a perfect fit in your window tracks. When you order, youll be prompted to provide your window dimensions so we can build your cat door to the exact specifications of your window.
  • Easy Install & Removal - Cat door installs in minutes with no tools required and is easily removable.
  • Safe & Secure - We offer options including small locking, large 4-way locking, and microchip locking. The microchip option is designed to prevent unwanted entry of stray pets by allowing only programmed pets entry while allowing any pet to exit. This can be connected for multiple cats.
  • Weatherproof | No Rotting, Warping, Breaking - We add weather stripping along all four sides of the base and brushing around the flap to keep out drafts and bugs. The PVC train molding is mold and weather-resistant. While it cuts and paints like wood, it does not warp, peel, or absorb moisture.
  • Get Your Exact Measurements - For horizontal windows (which open up and down), measure from the inside of the track on the left side to the lip of the window on the right side. For vertical windows (which open side to side) measure from the top of the inside of the track to the very bottom. See images and videos on listings for demonstrations.
  • Because this is custom built just for your window, we cannot accept returns. HOWEVER, most issues can be easily remedied and we'll make sure of it! Please be certain to reach out and our wonderful Customer Service Manager will answer your call, text or email. We only want happy customers! Fast Shipping - Most orders ship within 3 to 5 days. Please watch your emails in case we have measurement, or other questions. We want to get this perfect for you!

Size: Custom-cut to fit the length of your window.

  • Great product and wonderful customer service
Color: Clear
Prior to purchasing this product I reached out to customer service with questions about taking measurements. I received a quick, kind reply with helpful screen shots. Once the cat flap arrived I was immediately impressed with the quality! I purchased the clear version and you can’t tell the difference between the window and the cat flap surround. It was super easy to install and it works great. The flap itself is easy to swing and it’s quiet - my cats immediately caught on and used it the day of installation. I ended up adding some insulating foam around the flap but I’m not sure it was necessary. It did create nice, tight fit though. I would not hesitate to purchase from this seller. ... show more

  • Perfect!
Color: White
Perfect! I followed the directions before ordering, and it arrived in great shape, and it fits exactly perfectly! It's very sturdy and my cats began using it immediately.

  • Very happy
Color: Clear
I was pleasantly surprised to see they took the time to do the finishing touches, did not expect the felt edging around glass and the quality of the pet door is great. Fit exactly using thier measuring guidelines. Will purchase another one for a different window

  • Works like a charm
Color: Clear
I'm so glad we purchased this. We have a kitty that darts out the door anytime it opens. When it's so cold out I would have to stand outside multiple times a night calling for him to come back so I could make sure to get him back insise. It took a few days for the cats to figure it out but now they all come and go as they please and I don't have to worry about them getting stuck outside when it's so cold. It also does a good job of sealing up the space so air isn't coming through. I also appreciate how easy it was to install. Definitely recommend! ... show more

  • Perfect Ideal Cat Door for Odd Size Windows
Color: Clear
I sent them the measurements and they sent me my custom cat window insert. Looks well done, no rough edges!

  • Just as ordered and fit perfectly. Super happy
Color: Clear
The media could not be loaded. Love it! It fit perfectly and looks great. I ordered the regular sized cat door, that works great for 3 of my cats. For my Maine Coon it’s a tight fit, but brings peals of laughter to all

  • Simple is best
Color: White
This was easy to install and easy to work. This was my cat’s 2nd cat window (we moved) and they figured it out immediately. My only concern is that the cats can’t visually tell when the door is locked so I close the curtains when I lock it.

  • My cat loves it
Color: White
The cat loves the option to go out when she wants. Make sure you get the dimensions right (the seller called to double check, which I loved) and the installation will be very easy. Just slide the window and insert it. The seal works well, there hasn't been a problem of air or dirt coming into the house. We coupled this with a cat cage and connected the two. ... show more
