Why doesn't animal hair go grey?

Question

Human’s hair all goes grey, so why don’t animals go grey? You never see a grey gorilla!

Answer: A Silverback Gorilla is the alpha male gorilla and he has silver hair running down his back. So some animals do go grey. We go grey because our hair follicles run out of the ability to produce pigment and the default colour of hair is grey.
