Here's one - not a cat one, but a dog one that will give you a smile.

When I was a kid growing up, we always had a dog. Always a pretty big one, too - there was the German Shepherd mix, then Saint Bernard, then Great Dane mix. When I was a junior and senior in college, I moved out of the dorms and lived with a mom and young daughter, they had no pets. My role was basically to be the child's nanny, though we never called it that. Anyway, one night, I had been out very late, I don't even remember why. So when I came home, I entered very quietly, stepped inside, patted the dog and was most of the way to my room when it dawned on me where I was, and that no dog lived there. It wasn't a ghost, though, a very real irish Setter was quietly walking me to my room - cousins from Vermont were visiting for the weekend, and brought Zoe with them! The next morning they were kind of surprised she hadn't made any noise when I came in, but Zoe and I "knew" each other on sight, no fuss needed. Her job was to greet me at the door, my job was to give her some love!
