Lifetime financial exposure, clinical risk tiers, and routine veterinary spend for the Cornish Rex and the German Rex, audited line by line against the US national baseline.
Over their full lifetimes the Cornish Rex runs $12,681 ($975 / yr amortized) against the German Rex's $13,154 ($940 / yr). Choosing the Cornish Rex saves roughly $473 over the animal's lifetime. The Cornish Rex's premium is led by vet & insurance.

Why the underwriting tiers diverge, and the liquid buffer each breed warrants before acquisition.
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.
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 thin, low-insulation coat and a historically narrow gene pool create moderate, monitorable risk, though the breed has fewer documented syndromes than its more established rex relatives.
As with other rex breeds, a slipping kneecap occurs often enough to warrant a vet check during routine visits and, occasionally, surgery.
The thin, wavy coat offers little insulation or sun protection, making the German Rex more prone to cold stress and sunburn than a fully coated cat.
A historically small founding population raises the odds of recessive hereditary conditions surfacing, which is why genetic screening before breeding matters more than in a larger-population breed.
