It's funny how smart cats are. What seems to be an idiosyncrasy can end up being something very intelligent. Take, for example, where Friday sleeps. In the winter, he sleeps on the bed--day and night. He doesn't ever curl up with us, but he likes the cushy mattress and the warmth it holds. In the summer, he sleeps on the tile, where it's nice and cool. He also sleeps on the carpet right next to the tile. This didn't make sense to me for awhile, until I realized that he's actually choosing the spot not for it's fuzzy nature, but because it's next to the air intake for the air conditioner. The air intake creates a breeze, much like a fan, which we all know makes it easier to sleep. So, I'll label this with the "innovation" label, so that one day, when you're in a place with no fan, you can make sure you nap next to the air intake!
