Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
A breed-specific inherited myopathy combined with chronic skin and ear yeast infections from the oil-trapping curly coat creates recurring diagnostic and treatment costs beyond an average shorthaired cat.
An inherited muscle weakness that can show up in kittens as an odd gait or collapse and needs a specialist workup to diagnose correctly.
The curly coat traps skin oil without guard hairs to wick it away, leading to greasy skin, waxy ears, and recurring yeast infections.
A slipping kneecap common enough in the breed that some cats need corrective surgery to walk normally.
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 hereditary retinal disease and a rex-typical patellar luxation risk create moderate, monitorable costs, tempered by the breed's otherwise low grooming and food needs.
A hereditary, gradual degeneration of the retina that can lead to blindness and is best caught early with ophthalmology screening.
A kneecap that slips out of its groove, common enough in the breed that some cats need surgical correction to walk normally.
With no guard hairs to buffer temperature or sun, the skin is more exposed to sunburn, cold stress, and minor scrapes than a coated cat's.
