Ragdoll cats wash their faces on their own, licking their paws and then cleaning their faces. This is a way for Ragdolls to groom their whiskers, which are like "detectors" to the cat. Various factors can reduce the sensitivity of their whiskers, so washing their faces helps them straighten them and restore their sensitivity.
When Ragdoll cats wash their faces, it can have a massage effect. The cat's paws touch the facial nerves, which helps maintain their sensitivity. Washing their faces can also mask odors, which is related to their ancestors. Cats' ancestors lived in the wild and cleaned themselves to cover their scents and avoid being tracked by prey.
