Custom cat door that slides in your window! Can be stained or painted any color on request, the food is fully sanded and finished. The cat door is 6.25" x 6.25" with multi directional functionality shown in the pictures via the switch at the bottom. Perfect for a rental, or if you have glass doors! Options exist, but they are significantly more expensive and almost none of them are made from real wood. Can be made to fit any window, just let me know! I'll be happy to do anything I can to make it
