Maine Coon

Temperament

Friendly, curious, sociable, vocal (chirps and trills more than meows). Maine Coons love their family, get on with other pets, and are unusually playful and trainable for cats.

Exercise

Active and play-driven. Provide tall cat trees (they climb), interactive toys, and play sessions twice daily. Many enjoy walks on a harness.

Grooming

Long, silky double coat — surprisingly low-mat for the length. Brush 2–3× weekly; daily during seasonal moults. Check ear tufts and trim claws regularly.

Health

Hypertrophic cardiomyopathy (HCM — most common feline heart disease; DNA test available). Hip dysplasia (rare in cats but documented in Maine Coons). Spinal muscular atrophy (DNA test). Polycystic kidney disease. Buy from breeders who screen.
