Many horses enjoy playing with balls and plastic milk bottles suspended from stall ceilings. Tack stores sell toys for horses.
A horse's eyes are often a clue to its temperment. Large eyes usually show not only that the horse has good vision, but also a calm nature and intelligence.
Horses are herbavores, which means they do not eat meat. In the wild, horses can survive on grass and herbs if their grazing area is substantial enough. Due to the changing level of these food sources, horses drop weight in the colder, winter months and bulk up in the spring and summer.
