A pet is an animal that is domesticated or kept for companionship, pleasure, or amusement. Pets are typically kept in households and treated as members of the family. They are often chosen based on their ability to provide emotional support, companionship, and entertainment to their owners. Common types of pets include dogs, cats, birds, fish, rabbits, hamsters, guinea pigs, and reptiles, among others. Pets require care and attention, including feeding, grooming, exercise, and medical attention, to ensure their well-being and happiness.
