* Romping with mom reinforces bonding and a sense of security. Hoping to start a tussle, a three-month-old leopard cub swats its mother in Kenya's Masai Mara National Reserve. Wild or domestic, all cats toy with other cats of all ages, as well as with prey both dead and alive, inanimate objects, and virtually anything they can get their paws on. Hanging upside down from a branch, a young ring-tailed lemur plays with its mother in Madagascar. At play these extremely socia ble primates hang from trees, kick or grab one another, and stage pileups on the ground. Their troops include dominant females with a retinue of males and offspring.
