Indoor domestic cats live around 14 years on average, with many healthy cats reaching their 20s. Typical adult weight ranges from 8-12 lb, with males generally weighing 10-16 lb and females 6-12 lb, though breed affects this significantly -- Maine Coons can exceed 20 lb.

Domestication History
Cats are generally understood to have self-domesticated rather than being deliberately tamed by early humans. The process is thought to have begun in the Near East, possibly as early as 15,000 years ago, when early farming settlements began storing grain, which in turn attracted rodents. Wildcats tolerant of human presence preyed on those rodents and gained a reliable food source, and over many generations this mutually beneficial relationship gave rise to a distinct domestic population descended from the African wildcat.
Archaeological evidence shows cats had a close enough relationship with people to be transported to Cyprus roughly 9,500 years ago. From the Near East, domestic cats spread gradually across the Old World, though they did not become common throughout Europe and Asia until classical antiquity.
Popular Breeds
Most pet cats worldwide are not purebred, but a number of recognized breeds are known for distinct traits. The Maine Coon, which originated in the northeastern United States, is one of the largest domestic cat breeds, with males commonly weighing 18-22 lb, and is known for a long, dense coat and large, tufted paws suited to cold climates.
Other widely recognized breeds include the Siamese, known for its short coat, blue eyes, and vocal personality, and the Persian, known for its long fur and flat face. Breed can meaningfully affect a cat's typical adult size, coat-care needs, and temperament, even though most breeds fall within a broadly similar lifespan range.
