A Devon Rex has almost no guard hair, burns calories faster than its size suggests, and grows grease in its ear canals faster than most owners expect. The year runs on three rhythms: a ten-minute skin routine once a week, a weigh-in on the first of every month, and a heart scan that starts at twelve months.
The year at a glance
| Period | Skin and coat | Everything else |
|---|---|---|
| January-February | Wipe ears, chin and toe webs weekly; keep the room at 22-24 C | Monthly weigh-in; check the bed is draught-free |
| March-May | Weekly wipe; bathe only if the coat feels tacky | Spring weigh-in; book the annual check and dental look |
| June-August | Wipe twice a week in humid weather; dry the toe webs after a wipe | Watch for heat-seeking behaviour and greasy chin |
| September-October | Weekly wipe; add a warm damp cloth pass over the flanks | Autumn weigh-in; start the winter heat pad |
| November-December | Weekly wipe; bathe every 4-8 weeks as needed | Year-end weight, vaccine dates, parasite dose |
Skin: ten minutes a week, always in the same order
Start at the ear canal, move to the chin crease, then the neck folds, then between the toes. Those four spots are where Malassezia yeast collects, and the brown waxy debris is normal in small amounts but should never be left to cake. A soft pad with a vet-approved ear cleaner is enough; cotton buds pushed down the canal do more harm than the wax.
Use a rubber grooming mitt or a warm damp cloth rather than a brush. The hair is fragile and short, and a slicker brush or a metal comb pulls it out in tufts, leaving bald patches on the flanks and the base of the tail that take eight to twelve weeks to grow back. If a patch appears, check the collar and the spot-on residue first.
Bathing: every 4-8 weeks, not every week
Bathe when the coat feels tacky or the bedding starts to smell, which usually works out at every four to eight weeks. Use a mild degreasing shampoo, rinse for twice as long as feels necessary, and dry with a towel plus a warm room at 24 C. A Devon left damp in a 19 C room loses heat quickly and will sit hunched for hours. Mechanics are in how often to bathe a cat.
Weight: small frame, fast metabolism
Adults land between 2.3 and 4.5 kg. Weigh monthly on a kitchen scale with the cat in a carrier, or stand on a human scale holding it, and write the number down; a 200 g loss on a 3 kg cat is 7 percent of body weight and worth a vet call if it repeats. Growing kittens should add roughly 100 g a week up to five months, then slow to 50-70 g a week. Ribs should be easy to feel under a light hand and the waist visible from above.
Do not free-feed. These cats eat small amounts often and will graze a bowl all day, which hides a creeping gain of 300-400 g over a winter. Two measured meals plus one small mid-day portion suits most adults, with the wet food warmed slightly.
Heart screening and the muscle test
Hypertrophic cardiomyopathy is the breed's main cardiac concern. Book a first echocardiogram at 12 months, repeat every 12-18 months, and move to every 6 months once a murmur or a thickened wall shows up. From age 5, an annual listen is the minimum even if the cat looks well.
Congenital myasthenic syndrome is rare but testable: a DNA test for the COLQ mutation exists, and a breeder should be able to say whether the line is clear. Signs are a weak, crouching gait and regurgitation after eating, usually in the first year. Regurgitation is not vomiting, and a kitten that brings food back undigested two or three times a week needs a workup rather than a food change.
Heat, cold, and the 22-24 C rule
With no insulating coat, a Devon loses body heat fast. Keep the main room at 22-24 C, provide a covered bed, and put a heat pad on low under a blanket from November to March. In summer the same thin coat means sunburn on the ear tips and the white patches on the nose, so a window perch needs a blind or a sheer curtain between 11 am and 3 pm.
Radiators, hobs and hot water bottles are the other half of the risk: this breed lies against anything warm and does not move when it gets too hot. Fit a guard on exposed pipes and never leave a hot water bottle in the bed uncovered.
Play, company and climbing space
Two sessions of 10-15 minutes a day, one in the morning and one before bed, plus a food puzzle for one meal. Height does more work than floor space in an apartment: a 1.4-1.8 m tree against a wall, a shelf route at 1.5 m, and a window perch. A Devon left alone nine hours a day will over-groom its belly and thighs. A second cat or a midday visitor is part of the care plan, not a luxury. Ideas for indoor enrichment cover the rest.
Mistakes that cost the most
- Brushing the coat, which strips the wave and leaves bald patches.
- Bathing weekly and drying in a cold room.
- Cleaning the ears only when they look bad, so wax has already caked.
- Free-feeding and calling the winter gain "winter weight".
- Skipping the 12-month echo because the cat is only three kilos and seems fine.
- Leaving the cat alone all day in a flat with no height and no company.
When to call the vet the same day
Open-mouth breathing, a resting rate that stays above 40 breaths a minute, hind-leg weakness that appears over hours, or gums that look pale or blue. Book within 24 hours for a greasy, smelly ear that does not improve after seven days of cleaning, a chin that is raw or bleeding, a bald patch that spreads, or two weeks of loose stool in a cat that is also losing weight.
Four habits carry the year: wipe the four greasy spots every week, bathe every four to eight weeks and dry warm, weigh on the first of the month, and keep the echo appointment when the birthday comes round.
Frequently asked
Does a Devon Rex need regular baths?
Only when the coat feels tacky or the bedding smells, which usually means every four to eight weeks. Weekly bathing strips what little sebum the coat has and leaves the skin dry. Rinse twice as long as seems necessary and dry the cat in a room at 24 C, because a damp Devon chills quickly and will sit hunched for hours.
How often should I clean a Devon Rex's ears and chin?
Once a week, in a fixed order: ear canal, chin crease, neck folds, then between the toes. Small amounts of brown wax are normal for the breed, but caked debris smells and leads to yeast dermatitis. Use a soft pad with a vet-approved cleaner and never push a cotton bud down the canal.
When should heart screening start in this breed?
A first echocardiogram at twelve months, then every twelve to eighteen months for life, moving to every six months if a murmur or a thickened wall appears. From age five an annual listen is the minimum. Ask the breeder for echo reports on both parents from the past year before you buy a kitten.
