Polite Cat, also known as Ollie, became a viral meme over the summer of 2018. But is the cat's human-like 'polite' smile real or fake?

A cat owner's comments receiving over 6,300 likes, said: "They're so polite. My cats could never." Another person said: "IT WAS SO GENTLE." "That was the most polite tap lol," wrote a TiKToker.

After a few moments of staring, the cat slowly gets near the door and raises its paw. You would expect that the cat is going to scratch the door, but instead, the polite kitty softly knocks on it.
