SIZING CHART for up/down windows
Each unit comes with expandable side panels to cover the openings between the cat patio and the window frame, making each size patio fit a range of window sizes. (Be sure to check your window width using the instructions toward the bottom of this page. Next, look up the width of your window or windows below to determine which size unit best fits your needs, then use the link under that column to order that particular model or go to our order page.)
If you have a window that is at least 26 inches wide, we recommend the large size Kitty Peeper, as it utilizes more of the open window space. NOTE: While we caution customers to make sure their window width measurement is super-accurate, if your window is between 25 and 27 inches wide (opened interior width) then you could still use the large model, and just leave one of the side panel posts off.
Call us if you have ANY questions regarding measurement issues, and we'll happily assist you!
Note: We do sell an extension kit that expands the ranges of each of our units by about 6 inches ORDER BUTTON BELOW CHART
