Does anyone know the rules of the game?

I do. Cats flop on their side when an unfamiliar kitty is spotted and not acting aggressive to show they are not a threat. They are presenting tummies. It is a kind of tummy diplomacy.

When dreams become reality 😂😂😍

First rule of catflop: Don't talk about catflop.

Switching plates with my dog

They might be knowing🤣🤣😭😭

What game are these cats playing?

Panda knows the rules of the game 😂🥰

They’re signaling that they don’t want to fight. Baring the belly is a submissive stance.

The name of the game is Copy Cat

Three rollovers makes one flop. Add a meow and it's over. These two are pro's
