I had a cat do something like that once. Also a ginger cat too. We were on the balcony. I came inside for something, and when I came back out it was just in time to see her walking the ledge from our balcony to the next. She kept going all the way around the end of the building. I ended up running down the hall and knocking on the door of someone waaay at the other end of the building and saying "Hi, you don't know me, but my cat is going to be jumping on your balcony in a minute. Can I come in and get her?" She was fine. But I had to keep an eye on her outside.
