Are there any other animals that grow grey hair as they age besides humans of course?

Many animals grow grey hair. Domestic cats and dogs of course and almost all of the ape family. Also dog type animals such as wolves. The reason for the grey hair is the gradual loss of melanin which gives hair it's colour. Many animals do not live long enough for the melanin to deteriorate so keep their colours for all of their life. The types of animals kept for food, pigs, sheep, cattle etc do not live long enough to develop grey hair as they are usually slaughtered whilst young. Horses do though and most long lived pets. In the wild many animals are killed by predators as they get older or die of disease so they also never get the chance to go grey.
