Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
A generally hardy natural mutation breed whose defining curl gene brings mild, manageable skin sensitivity rather than a serious inherited disease.
The dominant keratin mutation behind the curly coat can bring thinner, more reactive skin in some lines, occasionally needing dermatology attention.
A general shorthair-level susceptibility to plaque buildup without regular home dental care.
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.
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, 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.
