Kurilian Bobtail Care Calendar: Coat, Weight, Heart

A Kurilian Bobtail year turns on two dates: the fortnight in March when the undercoat lets go, and the heart scan that starts at 12 months. Between them the work is a scale, a comb, and a bowl of water the cat is allowed to splash in.

The short tail changes none of that. The kink is a chain of fused or wedge-shaped vertebrae, not an absence of them, so there is no Manx-type spinal syndrome to plan around — but the tail should never be pulled, and the pom-pom at the end is where mats begin.

Weight: the number that sets everything else

Birth weight runs 90-120 g. At 8 weeks expect 800 g to 1.1 kg, at 6 months 3-3.8 kg, at 12 months 4.5-6 kg. Adults sit at 4-7 kg, males at the top of that band. A 7 kg male is not fat if the ribs are easy to feel under a thin layer, so score body condition monthly on the 9-point scale and aim for 5, not 4.

The risk window is the 6 months after neutering. A male can add 10-15% of body weight on unchanged portions, and the fat lands on the shoulders and rib cage, exactly where a double coat hides it. Cut the daily ration by 10% on the day of surgery, weigh every 2 weeks for 3 months, then monthly.

The coat calendar

Short-haired Kurilians need a rubber curry twice a week. Semi-longhairs need a steel comb twice a week and daily combing for 10-14 days in the spring molt, when the undercoat comes out in handfuls. A lighter molt follows in September for 7-10 days; comb in the direction of the coat, then back-comb once to lift the undercoat.

Period	Coat job	Weigh-in	Environment
Jan-Feb	Comb 2x weekly; feel armpits for felting	Monthly	Warm window perch; dry air raises static
Mar-May	Daily comb 10-14 days, then every other day	Every 2 weeks	Wash bedding weekly; hairball paste 2x weekly
Jun-Aug	Comb 2x weekly; no shaving	Every 2 weeks	Water dish to paddle in; shade above 26 C
Sep-Oct	Daily comb 7-10 days for the autumn molt	Monthly	Review the winter ration
Nov-Dec	Comb 2x weekly; tail and britches weekly	Monthly	Draft-free bed; the coat handles cold well

Tail, britches and three knot zones

Three places mat first, and all three are underneath: the armpit, the britches behind the hind legs, and the pom-pom itself. Comb each weekly with the cat standing, not sitting. A thumbnail-sized mat comes out with fingers and cornstarch; anything larger, or any mat that lifts the skin up with it, goes to a groomer — the skin of a bobtail is loose and rises into a scissor blade.

Never lift this cat by the tail, and never let a child use it as a handle. The kink is stable but it is still a joint. Sanitary trimming every 6-8 weeks keeps the rear clean without touching it, and the tail tip needs a monthly check for grease, because a bobtail that sits in its own tail curl collects sebum there.

Screening dates

Hypertrophic cardiomyopathy (HCM) is the cardiac concern in this breed group. A first echocardiogram at 12 months, repeated every 12-24 months, is the usual approach for a pet; breeding cats are screened before every mating. HCM in a calm cat shows as reduced play tolerance rather than coughing, so a cat that stops jumping onto its usual shelf is a cardiac suspect until proven otherwise.

Dental disease arrives from middle age rather than old age: a veterinary dental check every 12 months from age 3, every 6 months once tartar reaches the gum line, and brushing 3 times a week in between with pet toothpaste.

Food, water and the begging problem

An adult eats 5-7 oz of wet food or 1/2-2/3 cup of dry a day, split into 2 meals. Divide the ration between a puzzle feeder and a scatter feed rather than one bowl. A food-motivated bobtail trains its owner faster than the owner trains it, so fix the ration in the morning and do not revise it at 9 pm.

Water matters more than it looks on a double-coated cat. Provide a wide ceramic bowl refreshed twice a day, a second bowl in another room, and a shallow dish to paddle in — the breed genuinely plays with water, and that play is a hydration route.

Heat, cold and the room

The coat is built for the Kuril Islands, so cold is not the problem: this cat will sleep on a cool floor in January. Summer is the risk. Above 26 C it slows down and flattens out on tile, and panting means things are already bad. Screen the sunny window and measure resting respiratory rate at home — over 30 per minute is a same-day call.

Five care mistakes

1. Combing only the back. The armpit, britches and tail pom-pom are where mats form.
2. Free-feeding because the cat asks nicely. This is a breed that is obese by middle age.
3. Shaving a semi-longhair in summer. The coat blocks heat as well as cold, and regrowth is patchy for 3-4 months.
4. Skipping the 12-month echo because the cat is only a pet. HCM is silent until it is not.
5. Using the tail as a handle when lifting. Steady the chest and hindquarters instead.

When to call the vet

Not eating for 24 hours, a resting respiratory rate above 30, weight loss of more than 5% in a month, gums that are red at the tooth margin, a mat that has pulled the skin taut, or any reluctance to jump. Bring the weight log with you; a monthly number is more useful to a clinician than a memory of the cat looking thinner.
