I received an e-mail from a man named Lyle Goding. I love e-mails!

Hey

Your blog helped me with the basics for creating my cat ladder. I thank you and Buddy thanks you more.
When I first moved into my house I had a cat porch that was in a 1st story window. After I remodeled the pantry into a bathroom (with smaller window) the porch disappeared. But once I learned of the cat ladder I rebuilt the porch for the 2nd story and added a ladder.The porch has an In & an Out flap made of window screen with a weight at the bottom to prevent flapping. The roof is sloped and made of resin coated masonite. It fits into the window like an AC unit. Sometimes he lazes on the porch and waits for the dog to leave the back yard. In the summer Buddy loves it and in the winter he misses it. I love it in the summer since he no longer wakes me up at 4 AM to be let out.

Thanks again, Lyle
