I'm so jealous....I want one for Brandi. The cat on the other hand has created her own "dog run" that they both use. She clawed a hole in the bottom of the screen leading out to the second floor deck.
After years of fighting her on this I gave up and she finally won. There's no steps leading downstairs so they are perfectly safe.
They both lounge out there and pretty much go in and out as they please but Brandi will not go potty out there for some strange reason. Probably because there's no grass.
