The cave has been an integral part of the training curriculum at headquarters. The first photo shows Ms. Zulu when she was still a youngster, about three years old just like I am now.

I had to dig deep in the archives to find this old photo of myself when I was about 2 months old.

The third photo shows Sky in his first week at headquarters, when he had just discovered the cave.

The cave is very old; it dates back to many years B.Z. (Before Zulu). It looks like it’s part of a Stonehenge circle which could be true or not. The cave has been explored extensively by all four-legged beings, young and old, who resided at headquarters at some point in time. Over the years each of us has put our own paw-stamp on it so it means a lot to all of us including the two-legged ones.
