That's the mother cat Mister Mittens with two legs on her daughter Shiloh while grooming her throat with licks. Cats groom themselves daily but slapping licks at the throat is not possible. You need a buddy or a close relative, like a mother from seven years back.

Look at Mother when her daughter jumped into my old disgusting bed to wake her up. Even flat out on her side the momcat put her tail straight up on the horizontal.

Wake-up Mom!!!
