I remember "cat lipstick" being a big joke/meme 20 years ago on Fark.com. Ceiling Cat was omnipresent and FB- was the father of the multitudes.
When my cat gets diarrhoea I have to keep a close eye out for telltale brown kiss marks on the floor!
I'm pretty surprised to learn that cats can be trained to follow commands!
> To complete the experiment, Henry and his mom, Kerry Hyde, bought non-toxic lipstick and applied it to each of their cat's anuses. Then, the cats were given commands.
Rigor. Will it reproduce?
