The Cat Terrace

The DIY Window Door and Catio Cage



Designed to give your cat(s) or small dog(s) access to the Great Outdoors! You regulate their access by simply opening or closing the window. Weatherize the window for year-round use, plans included.​​

The Window Door eliminates having to saw a hole through your exterior door or wall as with most pet door installations. It also has a very low impact on your home, a few screw holes in your exterior wall and a door size hole cut in your window screen.
