Y is for ......

One thing most people know about Yaks is that they are winter survivor specialist for bovine 🐮. Cold? They have woolly fur. They also have a thick layer of subcutaneous fat to prevent heat loss. They do not have much sweat glands.

At the same time, they have many differences with their more common bovine cousin the cow. Cows moo. Yaks are pretty quiet except for their grunts. And the Yak's shit does not stink.
