Sheep are found in the highlands, with their thick wool to protect them from cold. You will find them on the slopes of the Aberdares (Nyandarua), Mount Kenya and other mountainous places.
There were more sheep during the colonial era when wool was a valuable export. Today, lamb or mutton has more value than wool, whose market has diminished. But think of it, you get wool from a sheep several seasons before the butcher does his work.
