Scraggles' Dream Come True!

Scraggles is thrilled with her newfound freedom and so am I! The fit and look is snug and smooth. She didn't ever take to pushing the thick door open as it provides too much resistance with the magnetic closure for her sensitive little face. So we adapted it for her by propping the door open with a stick and making a makeshift flap out of lightweight, easy to push, clear plastic. Now she loves it! Maybe an alternate, lightweight floppy flap door could be made and included with the hard door for cats with facial sensitivities hehe.

Great cat door!!!

I love this window insert with the cat flap door. I had tried a cheaper adjustable option that didn't work well in my window and didn't have a secure flap. I decided to spend the extra money - it was easy to submit my measurements, the windows arrived quickly and fit perfectly. The cats were using it within 2 days. I even ordered a 2nd one for another window in the house. The actual flap has a great magnet and closes completely. Also, we've had several bad storms and the plexiglass has created a good seal so no water has gotten in the window. The plexiglass is also really clear so I haven't lost any light in the room either. I would highly recommend!

Exactly what i wanted and needed

I looked at a lot of the offered cat door inserts and evaluated them against my needs. This door and window insert fit my needs and the price was within range. I measured and re-measured to make sure i understood how it was supposed fit and install . I finally felt confident and made the call and spoke with Liz. She took the measurements and said the insert should be sent and received in about one week. That is exactly what happened. I received the package and had the insert installed within 15 minutes of receiving it . It fit so nicely and looked so good that my wife and I were both impressed. We are happy and out cat is very pleased. The cat door itself is very good quality and quiet.

Exactly what we needed

I moved into an apartment from a house, so my cat, Mitts, is now indoor only. In my apartment, I have a window from the living room to a screened in porch where Mitts can walked all around the inside ledge. The window insert is needed when we need heat or air conditioning. I decided to go the extra mile and purchase the plexiglass. Sure, it's a bit pricey. But, it fits perfectly, easy to put in, measuring was a piece of cake, and it works great. I like the plexiglass because it looks good visually and doesn't stand out like the solid version. The seal is as good as it can be, so I'm really satisfied. Mitts used a dog door at our house - she needs a little encouragement as this version is smaller.
