How Much Does a Devon Rex Cost? (2026 Full Cost Breakdown)

The Devon Rex is a small, light regular-size cat at 2.5 to 4.5 kg, giving it the lowest food line in this group at about US$77–121 a year. Routine veterinary care runs the standard US$425–635.

Its short, curly rex coat is delicate and can thin, so it carries a medium grooming need at US$300–450 a year, mostly gentle bathing and skin care rather than brushing, since the fragile fur is easily damaged.

The Devon Rex is in the medium risk tier on documented predispositions to hypertrophic cardiomyopathy (HCM), patellar luxation, a hereditary Devon Rex myopathy and skin conditions. That prices insurance at about US$278–519 a year as a kitten, US$348–649 as an adult, and US$881–1,391 once senior. Adult premium plus food, vet and grooming gives an annual figure of US$1,150–1,855, and over a 12 to 16 year life that totals US$15,970–33,870. Two exposures are shown separately and are not in those totals: heart-condition treatment at US$1,100–5,000 and allergy testing or treatment at US$200–2,500. First-year setup adds US$370–1,190. The steep purchase price, not the running costs, is the Devon Rex's largest single outlay.

The purchase and one-time setup pull the first year to US$3,320–6,045, with the high buy-in of US$1,800–3,000 front-loading the cost. After that, the very low food line partly offsets the medium grooming and insurance, holding the annual figure at US$1,150–1,855 across a 12 to 16 year life. The steep purchase is the largest single outlay; the recurring cost is mid-range for these cats. Its small size keeps food modest, while the delicate coat and health profile are what hold the annual figure up.
