Give Your Cat the Freedom It Deserves:This aluminum cat door for window gives pets an easy way to come and go—no drilling or tools required. The adjustable panel fits most window sizes, and the clear flap lets curious cats peek outside. Simple to install and built to last, it's a thoughtful upgrade for you and your feline friend.

Works great! My cat absolutely loves it and took to it in a day. We both appreciate that she doesn’t need my help any more getting out, as raising the window was a hassle. The ability to lock it so she can only come in makes it easy to set a time when we don’t want her to go back out while still letting her come in of her own volition. Also great that we’ll be getting fewer mosquitoes in the house. I wish there was more padding included since the knobs for extending the panels make it so that the bottom is not flush with my window.
