Cornish Rex Care Calendar: Heat Safety, Knees and Muscle

The Cornish Rex has no guard hairs and no undercoat, a body that behaves like a racehorse, and a habit of sleeping against anything warm. Most of the year's work is temperature, a five-minute weekly wipe, and keeping a lean frame.

The year at a glance

Period	Warmth and safety	Coat and body
January-February	22-25 C; heat pad on low; draught-proof bed	Weekly wipe; monthly weigh-in
March-April	Heat on until nights stay above 18 C	Weekly wipe; check belly for bald patches
May-June	Shade the perch: curtains, not sunscreen	Bathe if greasy; nails every 3 weeks
July-August	Coolest room; no hot radiators to nap on	Watch water intake; weigh monthly
September-October	Test the heat pad before the first cold night	Autumn weigh-in; run hands over the coat for lumps
November-December	Guard exposed pipes and hobs; no uncovered hot water bottles	Year-end weight, vaccines, parasite dose

Why the room temperature is a medical issue

With no insulating layer, a Cornish at 18 C loses heat continuously. Keep the main room at 22-25 C, warmer than most guides suggest, with a covered bed and a heat pad on low from November through March. A cat hunched over the radiator all evening, or under the duvet for 16 hours, is telling you the room is too cold.

Kittens under 12 weeks regulate poorly: a nest at 26-28 C for the first month home, dropping 2 C a week, is common practice. A kitten cool behind the ears and along the belly should be warmed against skin and seen by a vet.

Burns: the risk nobody plans for

Thin skin plus a heat-seeking habit makes burns a real problem. Radiators, hob rings, open oven doors, hair straighteners and hot water bottles cause contact burns that show as a dark scab two or three days later. Guard exposed pipes, shut the kitchen door while cooking, cover any heat pad. A burn bigger than a thumbnail, blistered or weeping, needs a vet within 24 hours; no butter, oil or human ointment.

Summer brings sunburn on ear tips and the pale nose, plus heat exhaustion above 30 C. Panting, drooling or lying flat and unresponsive is an emergency.

Coat care: five minutes, once a week

No brush. A brush flattens the wave and scratches thin skin, and a slicker takes the coat off in strips. Wipe the coat with a warm damp cloth weekly, then dry. The ears and chin get a clean every seven to fourteen days, and a bath every six to eight weeks only if the coat feels greasy. Dry in a warm room; a wet Cornish in a cool bathroom shivers within minutes.

Some bloodlines shed on the throat, temples and underside in a predictable cycle each year. Photograph the patch monthly with a ruler in frame: a smooth, stable patch is usually cosmetic, while a red, itchy or spreading one needs a skin check. Technique is in brushing and coat care; for this breed, only the wipe-down section applies.

Weight and muscle, not just kilograms

Adults weigh 2.7-4.5 kg and are dense for their size, so the scale reads heavier than the cat looks. Weigh monthly and use body condition as the tiebreak: ribs easy to feel, a visible waist, a firm thigh. A Cornish that stops climbing is more often 300 g too heavy than lazy.

Protein needs are high because muscle mass and activity are high. Two measured meals plus one small third meal suits adults; a kitten under six months eats three to four times a day. Watch water: a fountain or a wet-heavy diet covers the gap, and dark, scant urine over two days is worth a call.

Knees: the check that takes ten seconds

Patellar luxation occurs at low but real frequency. Once a month from kittenhood, feel each kneecap with the leg relaxed, then flex and extend the joint. Look for a knee that slips sideways with a click, or a cat that skips a few strides on one hind leg and then walks normally. A vet should grade both knees yearly; grade 2 or higher, or any skipping, means an orthopedic look before arthritis sets in.

Jumping down is the other load: a 1.8 m tree is fine to climb, but add a shelf partway down so the landing is not one drop onto a hard floor.

Exercise: three sessions, or the house pays

Two or three sessions of 10-15 minutes a day, a wand toy worked at speed, fetch up a staircase, a puzzle feeder for one meal. A bored Cornish becomes a nocturnal specialist in knocking things off shelves, solved by 20 minutes of chase play before bed, not by closing doors.

Provide 1.5 m of vertical route, ideally a circuit so the cat can run rather than jump. A window perch with a view of birds buys an hour of quiet; more options sit in indoor cat enrichment.

Heart screening and the annual appointment

Hypertrophic cardiomyopathy is the main breed concern. First echocardiogram at 12 months, then every 12-18 months, and every 6 months once anything shows. Ask for echo reports on both parents from the last 12 months. At home, count sleeping breaths: under 30 a minute is normal, a persistent 35-40 means a call within days, and open-mouth breathing is an emergency.

Mistakes that cost the most

• Treating 19 C as a normal room temperature for this breed.
• Brushing the coat to "help" it, and flattening the wave for months.
• Letting the cat sleep against a radiator or uncovered hot bottle.
• Bathing and then letting the cat air-dry in a cool room.
• Free-feeding an animal that never stops moving.

When to call the vet the same day

A burn, blister or dark scab; panting or drooling in a warm room; a cat that feels cold and will not warm up; sudden hind-leg weakness; open-mouth breathing or a resting rate above 40. Book within 24-48 hours for a knee that skips twice a week, an itchy bald patch, greasy ears after two weeks of cleaning, or no food for 24 hours.

Keep the house at 22-25 C, wipe the coat once a week and never brush it, feel both knees on the first of the month, and count sleeping breaths when the cat looks off. Those four habits prevent most of what this breed is prone to.
