Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
The achondroplasia-linked short legs create a moderate, ongoing orthopedic monitoring need rather than one universally severe defect.
The short-legged gene is linked in some Munchkins to an exaggerated inward curve of the spine, which can compress the chest cavity and, in severe cases, affect breathing or organ function.
A sunken breastbone shows up more often in short-legged breeds than average, and moderate to severe cases can need surgical correction in kittenhood.
The shortened limb bones alter gait and joint loading, which can bring on stiffness and mild arthritis earlier than in a standard-legged cat of similar age.
Coat load, energy, and temperament shape boarding, grooming, and handling costs beyond the medical ledger.
Adjust the compounded annual CPI. Veterinary clinical services have trailed near +7.8% YoY; the pet-care basket sits lower.

A documented but manageable hypertrophic cardiomyopathy risk is offset by an otherwise exceptionally hardy, long-lived breed with no orthopedic or respiratory predisposition, placing it below average overall.
A thickening of the heart's left ventricle wall that can go unnoticed until an ultrasound is done; the breed carries a documented predisposition worth periodic cardiac screening.
A sturdy build and easygoing temperament make this breed prone to weight gain, which compounds joint and metabolic costs over its unusually long lifespan.
Standard-rate dental buildup affects this breed like most domestic cats, needing periodic professional cleanings across its long life.
