My new balcony is finally finished! It took me a couple of weeks to get it cat proofed once they had built it but the cats got their first run of it tonight. It was hysterical! After sniffing and rubbing the whole thing they started racing around like maniacs! Just as predicted, they chased eachother out one window and in the other (it wraps around the apartment). They are now both conked out on te bed. I'm so happy that they finally have a place (albeit small) to be outside. Of course, I like it too!
