Health, Lifespan, and Veterinary Care

Siberian Health Profile

• Average Lifespan: 12-18 years.
• Primary Health Concern: Hypertrophic Cardiomyopathy (HCM). Responsible breeders screen for this.
• General Health: Considered a robust, hardy breed with fewer common genetic issues due to its natural development.

Maine Coon Health Profile

• Average Lifespan: 12-15 years.

Annual Veterinary Cost Estimate (2026)

Note: Costs vary significantly by location and individual veterinary practice. Pet insurance is highly recommended for both breeds.

The Allergy Question: Hypoallergenic Qualities

• Siberian Cats: While no cat is 100% hypoallergenic, many Siberians produce lower levels of the primary cat allergen (Fel d 1). Many allergy sufferers report significantly fewer reactions, but individual responses vary. Some breeders offer allergen testing.
• Maine Coon Cats: They produce standard levels of allergens and are not typically recommended for people with moderate to severe cat allergies. Frequent grooming and use of HEPA filters can help manage allergen levels in the home.
