Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
A well-documented cardiomyopathy predisposition combined with a known clotting-factor disorder in some lines creates recurring cardiac and surgical-risk cost above breed-average.
One of the most consistently reported heart conditions in the breed, thickening the heart wall and often managed with lifelong medication once detected.
A rare inherited clotting-factor deficiency documented in British Shorthair bloodlines that can turn a routine surgery into a higher-risk, higher-cost procedure.
The breed's stocky, round-bodied build gains weight readily on free feeding, adding joint stress and diabetes risk over a long lifespan.
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 orthopedic predisposition combined with a heavy-boned build's obesity and urinary tract risk pushes recurring cost above breed-average.
A kneecap that slips out of its groove, documented in Chartreux lines, ranging from an occasional skip to a gait that needs surgical correction.
A robust, heavy-boned build combined with a hearty appetite makes weight gain easy without portion control, adding joint and metabolic strain over time.
A cluster of bladder and urethral conditions common in stocky, less active cats that can cause painful, sometimes urgent, urinary blockages.
