Visual Differences
Telling a Maine Coon from a Siberian
Siberians are smaller (8–15 lbs), have a shorter, thicker triple coat, and are more round-faced than the long-muzzled Maine Coon.
Telling a Siberian from a Maine Coon
Maine Coons have a square muzzle with high cheekbones, a silky coat with less undercoat, and a longer tail reaching at least the shoulder. Their ears are larger and more heavily tufted with lynx tips. Siberians have a rounder head, a shorter muzzle, a denser triple coat with more seasonal variation, and a stockier, heavier build for their frame.
Maine Coon Key Markers
- Ear tufts (lynx tips) — the most distinguishing feature of a Maine Coon cat; long, dramatic tufts of fur sprouting from the ear tips, unlike the rounded, lightly tufted ears of other large breeds
- Large, rectangular body — a massive, broad-chested frame with a long, muscular torso; males reach 13–18 lbs, up to 40" from nose to tail tip
- Long, thick, bushy tail — wraps around the body like a built-in blanket, tapering from a wide base to a plumed tip; reaches at least the shoulder when extended
Siberian Key Markers
- Triple coat that naturally repels water — a dense woolly undercoat, a protective awn-hair middle layer, and a longer, coarser outer guard coat; the coat thickens dramatically in winter and sheds in summer, varying by season in density and length
- Round, broad head with full cheeks, a short blunt muzzle, and a gentle curve from forehead to nose with a visible but soft stop — the profile is rounder than the Norwegian Forest Cat’s triangular face
- Large, almost round eyes set wide apart in gold, green, copper, or blue (white cats); eye color is independent of coat — the expression is open and sweet, never harsh
Temperament & Personality
Maine Coon
- Gentle and friendly with children and dogs
- Dog-like personality — follows owners, fetches, comes when called
- Highly intelligent and trainable
- Playful well into senior years
- Excellent mouser (historically a working farm cat)
Siberian
- Dog-like loyalty — follows owners from room to room, greets at the door, and comes when called
- Agile and athletic — loves high cat trees, shelves, and interactive play that mimics hunting (fishing rod toys, fetch)
- Gentle with children and other pets — the breed’s history as a farm and forest cat in harsh climates developed a calm, resilient temperament
- Moderate vocalization — communicates with chirps, trills, and soft meows rather than loud demanding yowls
- Intelligent and curious — opens doors, solves puzzle feeders, and learns tricks; needs mental stimulation to prevent boredom
- Seasonal coat changes — heavy winter coat with full ruff and britches sheds in spring; grooming needs vary dramatically by season
Health Notes
Maine Coon
- Hypertrophic cardiomyopathy (HCM) — the most common heart disease in Maine Coons; genetic testing available
- Hip dysplasia — more common in large-breed cats
- Spinal muscular atrophy (SMA) — a neuromuscular disorder with a DNA test
- Obesity risk due to large appetite — monitor portions carefully
Siberian
- Hypertrophic cardiomyopathy (HCM) — genetic heart disease affecting Siberian cats; echocardiogram screening recommended for breeding cats
- Feline lower urinary tract disease (FLUTD) — moderate predisposition, likely linked to the breed’s Russian cold-origin preference for conserving water; high-moisture diet recommended
- Dental disease — the short blunt muzzle contributes to tooth crowding; regular dental care and annual oral exams advised
- Hip dysplasia — more frequent in large, heavy-boned breeds; maintaining healthy weight reduces symptom severity
- Allergen variation — individual Siberians produce different Fel d 1 levels; no guarantee a specific cat is hypoallergenic even within the breed
