NYC ninja rats: Rodents caught on video roughousing on subway platform

They know ka-rat-e.

A pair of kung-fu rats channeled their inner Bruce Lee — caught on video while fighting on a Brooklyn subway platform.

For nearly a minute, the Teenage Mutant Ninja Turtle wannabes leapt into the air, flipping over onto their backs, and delivering airborne blows — all to the delight of the women behind the lens.

The footage was shot on July 11 at the Grant Avenue Station in Brooklyn’s Cypress Hills neighborhood.

Rats are known to gently nip, bite and wrestle with each other or their mothers as a form of play fighting, according to PetMD.

The website said such behaviors are healthy and normal, helping the rodents forge bonds and learn appropriate social cues.

Typically, when rats fight for territory or food, they make extremely loud shrieks, hisses or squeaks, according to the Lafeber Company.

One Reddit user confirmed the rats were likely playing on the platform.

“If they were fighting, they’d be using their incredibly sharp teeth, and there would be missing eyeballs and entrails hanging out of their abdomens,” the Redditor wrote.
