Wild or domestic, cat species all over the world show the same behavior. My housecat cleans its fur just as that lion in Africa, or that tiger in India, or that snow leopard in the Himalayas. In Africa I watched a lioness do exactly the same thing as the bobcat in my drawing. Using pencil often is a nice alternative to using brush and paint. It's clean, and a pencil drawing can have a special graphic charm and often is more decorative than a painting. Mostly those pencil drawings are done as studies for future paintings. - CB
