What is a "stablemate"?

A stablemate is a horse that is kept in the same stable or barn as another horse. However, it can also refer to any animal that is similar or comparable to another. In the context of horses, a stablemate is typically a horse that shares similar physical characteristics, temperament, or training with another horse. The term is often used in the horse racing industry to refer to horses that are owned or trained by the same person or organization. In addition, the term can be used more broadly to describe any two individuals or things that are closely associated with each other or considered to be of the same kind.
