A pet is an animal kept primarily for a person's company or entertainment rather than as a working animal, livestock, or laboratory animal. Common pets include dogs, cats, birds, and fish. They provide companionship, emotional support, and joy to their owners, often becoming integral members of the family. Caring for a pet involves meeting their needs for food, shelter, and medical care. Many pet owners enjoy the responsibility of training and socializing their pets, which can enhance the bond between them. Pets can also contribute to their owners' well-being by reducing stress and encouraging physical activity.
