lack of information

I placed my order nearly a week ago. I am building a catio around the window insert and I have a question about dimensions. I have called twice and texted twice. I am not getting a reply. Just need a simple answer to my question. Perhaps this will get their attention.

Wonderful!

Thank you for the wonderful customer service! This window insert is super profesh. It's a lot clearer than I thought it'd be. You almost can't even tell it's there!

These folks were so nice in taking a custom order from me. I needed specific measurements to line up with an outside catio entrance through my wonky old aluminum window & storm window. Works like a charm!

Wonderful window!!

I was sick of cleaning out a litter box. This window solved all our problems with our kitty!! The customer service was very good. Our window was cut perfectly. It has been several months since we installed it and it is still going strong and functioning well. Our cat is much happier now and so are we! Now we have the occasional issue of our cat bringing in "presents" to us... lizards, chipmunks, etc... but I can handle that verses the stinky mess before the window.

We bought the cat flap for Riley, my sight-impaired cat. We didn’t want to cut our metal doors so going in and out a window is perfect. It is well made and fits the window perfectly. Customer service is great and it shipped quickly. My husband actually built a ramp so he can come back in easily since the window is fairly high off the ground and Riley can’t jump as high with his visual impairment. We tried to keep him in but he loves going outside and can’t jump over our fence so he’s fairly safe.
