The term 'stable residents' refers to the animals that live in a stable, such as mares and horses. Mares are female horses, while horses are male horses. Both mares and horses are kept in stables for riding, racing, or breeding purposes. They are typically cared for by a stable hand, who provides food, water, and exercise for the animals. Stable residents are important to the equestrian industry, as they provide a source of income and entertainment for many people.
