On Facebook, when someone has a picture of a cat as their profile picture and no picture of themselves anywhere, what does that say about them?

Hi! I’m drugged up on allergy meds right now (of the prescrip-shee-own variety, plus Prednisone (sp?))

Does it mean, they’re wanting to remain private, so, no pictures of themselves?

Or, they don’t think that they’re cute enough, so, a kitteh picture goes up?

Or, they are this fella in an orange kitteh disguise?

Or, they are a real MOOFiLY POOFiLY kitteh?

Just having fun.
