Lion

When resting, lion socialisation occurs through a number of behaviours; the animal's expressive movements are highly developed. The most common peaceful, tactile gestures are head rubbing and social licking, which have been compared with grooming in primates. Head rubbing – the nuzzling of the forehead, face and neck against another lion – appears to be a form of greeting and is seen often after an animal has been apart from others or after a fight or confrontation. Males tend to rub other males, while cubs and females rub females.
