When our old (old as in moved) neighbours used to go on vacation, they would ask me to come over and feed their cat Molson while they were away. Molson was a very clever cat and spent most of her time, while they were gone, doing mysterious cat things, since this was before it became law to keep pet city cats from wandering. Even though she was very independent, at least one day, while the neighbours were gone, Molson would get lonely. Usually this just meant I would hang out with her at their house for a bit, but one night she actually came to OUR door and wouldn't leave until I came and got her. She's probably the reason I still like cats even though I am allergic to them.
