Centuries ago the remote rugged islands off the west coast of northern Scotland provided a home for the wild "Kyloe", an ancestor of the present day Highland cattle. They were small and predominantly black.
Domestication and cross breeding with their larger and mostly red cousins from the Scottish mainland has produced the animals we presently know as Highland Cattle. Miniature Highland Cattle are a reproduction of the older animal and are defined as Highland Cattle that remain under 42" tall at the shoulder when fully mature. Prior to 1900, Highland Cattle as small as 350 pounds were not unusual. This compares with full size Highland cattle weighing 800 to 2000 pounds today.
