I have an indoor cat. She greets me at the front door, like a good indoor cat.
Except this morning, when I returned home in an unfamiliar car, from the wrong direction. As I got out of the car I saw my good indoor cat barrel down a treetrunk, scoot across the lawn, and leap up a wall and through a window I didn't know she could access.
Then she demurely greeted me at the front door like any good indoor cat.
How long has this been going on?
