I've been wanting to learn a bit about character modeling so I headed over to Blender.org and checked out some tutorials. After a couple hours I came up with this! I kept the Makerbot in mind while modeling so no steep overhangs or "floating" segments, so it should print well for you. It has some flaws, but I'm pretty happy for a first attempt.

Print it out, add some mounting tape or magnets and place it on the ceiling in your home, car, or place of employment. May it remind you that the omnipresent feline is always watching. Always...
