I just ran into Num (5-ish) today, when she and her friend were wandering around Pacific Heights. It turns out the woman with Num was just cat-sitting for a while. Num is used to going out for walks every day, and has been since she was a kitten, so she took her out to Lafayette Park for some playtime.
Num has another awesome story associated with her, too, though. It seems that her mom was traveling in Bhutan five years ago. She was indoors in the evening, and heard some commotion outside. She opened the door, and a kitten streaked inside. Mom shut the door just in time to keep the wild dogs who were after her from getting in. And they’ve been partners ever since.
