American Bobtail Health Problems: What Every Owner Needs to Know (2026)

American Bobtails are a relatively hardy breed, but like all pedigree cats they carry specific health risks every owner should know before buying. Here's the honest breakdown.

American Bobtail Health at a Glance

Condition Risk Level Notes
Hypertrophic Cardiomyopathy (HCM) Moderate Most significant health concern; cardiac screening recommended
Spinal issues (tailless variants) Low–Moderate Rumpy variants with no tail can have spinal defects
Hip dysplasia Low Rare but documented in the breed
Obesity Moderate Muscular build can mask weight gain; monitor diet
Dental disease Moderate Common in cats generally; regular dental care recommended

Hypertrophic Cardiomyopathy (HCM)

HCM is the most significant health concern in American Bobtails. It's a thickening of the heart muscle that can lead to heart failure. It affects many cat breeds and American Bobtails are not immune. Reputable breeders screen breeding cats for HCM annually. Ask your breeder for current cardiac screening results for both parents before purchasing a kitten.

Spinal Issues in Tailless Variants

American Bobtails naturally have a short, bobbed tail. "Rumpy" variants — those with no visible tail — can carry spinal defects similar to those seen in Manx cats. Reputable breeders select for a visible stub tail to avoid these issues. Avoid breeders producing tailless American Bobtails.

Obesity

American Bobtails are muscular and dense. Their build can mask gradual weight gain. Monitor body condition regularly — you should be able to feel ribs without pressing hard. Regular outdoor activity helps maintain healthy weight. See: American Bobtail Hiking Guide

What to Ask Your Breeder

Health screening is the single most important factor in buying a healthy American Bobtail. A reputable breeder will provide HCM screening results, genetic testing documentation, and a health guarantee. Full checklist: Questions to Ask an American Bobtail Breeder

Lifespan

A healthy American Bobtail typically lives 13–15 years. See: American Bobtail Lifespan
