This turned out wonderfully! I used this as the basic framework to modify and make larger. After reading other reviews, I left off the entire back panel and added those to the sides and front. Doing so made the roof too small, so I went to the hardware store and made my own. I spent an additional $100 on modifying this but it is worth it. Still needs a few finishing touches to make perfect and added some potted catnip to keep her happy!
