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 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.
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.

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.
