The Maine Coon is one of the largest domestic cat breeds, prized for its tufted ears, bushy tail and sociable, easygoing nature. Despite their imposing size they are typically affectionate and people-oriented, often following their owners from room to room. Their semi-long coat and gentle temperament make them a rewarding companion for households that can meet their grooming needs.
Maine Coons can be predisposed to hypertrophic cardiomyopathy (HCM), hip dysplasia and, in some lines, spinal muscular atrophy and polycystic kidney disease. Choosing kittens from breeders who screen for these conditions and scheduling regular wellness exams helps catch issues early. Keeping a complete, shareable health record of vet visits, screenings and any symptoms makes it easier for your veterinary team to monitor trends over time.
Their silky, semi-long coat benefits from brushing two to three times a week to prevent mats and reduce hairballs, with extra attention during seasonal shedding. Routine nail trims, dental brushing and weekly ear checks round out their care. A large, sturdy litter box suits their size, and most Maine Coons tolerate grooming well when introduced gently.
Maine Coons are friendly, intelligent and playful well into adulthood, often described as having a dog-like personality. They enjoy interactive toys, puzzle feeders and even learning to walk on a harness, and many are fascinated by water. They tend to be sociable with children and other animals, making them a good fit for active, attentive homes.
Feed a complete, high-quality diet appropriate for the cat's life stage, with portions matched to their large frame to avoid excess weight. Because their size can mask gradual weight gain, monitor body condition regularly and provide fresh water at all times. Your veterinarian can help tailor calorie needs as the cat ages.

Adult Maine Coons typically weigh 10–25 lb (4.5–11 kg) and can measure up to about 40 inches long including the tail. They grow slowly and may not reach full size until three to five years of age.
Many Maine Coons show an unusual fascination with water, batting at faucets or dipping paws in their bowls. This is thought to relate to their water-resistant coat and working-cat heritage, though individual personalities vary.
