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.

> 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?

I'm pretty surprised to learn that cats can be trained to follow commands!

When my cat gets diarrhoea I have to keep a close eye out for telltale brown kiss marks on the floor!
