American Bobtail Lifespan: How Long Do American Bobtails Live? (2026)

American Bobtails are a long-lived breed when properly cared for. Here's what owners and breeders report about lifespan, and what affects it most.

How Long Do American Bobtails Live?

The typical American Bobtail lifespan is 13–15 years. Well-cared-for cats from health-tested lines regularly reach 15+ years. The breed's broad genetic base — compared to more narrowly bred pedigree cats — contributes to its relative hardiness.

Factors That Affect Lifespan

Factor Impact
Breeder health screening High — HCM-screened lines live longer on average
Indoor vs outdoor lifestyle High — supervised outdoor cats outlive unsupervised free-roaming cats
Diet and weight management High — obesity shortens lifespan significantly
Veterinary care High — annual wellness exams catch issues early
Dental care Moderate — dental disease is linked to organ damage over time

HCM and Lifespan

Hypertrophic Cardiomyopathy is the most significant health risk affecting American Bobtail lifespan. Buying from a breeder who screens breeding cats annually for HCM is the single most impactful decision you can make for your cat's longevity.

Outdoor Activity and Lifespan

Supervised outdoor activity — leash walking, hiking, camping — supports healthy weight and mental stimulation without the risks of unsupervised free-roaming. American Bobtails that get regular outdoor enrichment tend to maintain healthier body condition into old age. See: American Bobtail Hiking Guide
