Geeky pet owners probably already know that their cat(s) can sleep just about anywhere, including tiny boxes, on top of heaters / air conditioners, in small holes in the corner, and apparently, on top of laptop keyboards. Simply put, they sleep up to 16-hours a day, so anywhere that’s warm and / or comfortable usually does the trick.
