I'm confused on how to vote. Intuitively I think I click on whichever I think is better. But when I hover over the the non-kitten, it gives me a weird message like "Get Real", "Are You Blind?", "Not Now, Not Ever", and "Not Likely". Which kind of leads me to think that I'm voting for the kitten even when clicking on the non-kitten?
