Donskoy screening runs on 3 tracks that share 1 calendar: periodontitis, seborrhea with fold dermatitis, and hypertrophic cardiomyopathy (HCM). The mouth is scored every 6 months from 6 months of age, the skin gets a 5 minute weekly routine that costs almost nothing, and the echo starts at 12 months. Year 1 runs 350 to 700 dollars, about 2,520 to 5,040 yuan at 7.2, and the dental line is the one that grows every year.
Periodontitis: score the gum at 6 month intervals
Hairless cats carry heavy calculus early: gum inflammation by year 2, then attachment loss, then a loose incisor. Screen it in 4 numbers per side: gum redness 0 to 4, probing depth in millimetres where 1 mm and under is normal and 2 mm or more means attachment loss, bleeding on probing, and mobility 0 to 3. Score at 6, 12 and 18 months, then every 6 months. Home care is brushing, and it is not optional in this breed: daily with a soft brush and enzymatic paste, 3 times a week as the floor, plus a chlorhexidine gel 2 times a week. Chlorhexidine rinses and gels are hygiene products, not treatment; antibiotics and pain relief are by vet prescription only.
Tooth loss: what changes when a tooth goes
A Donskoy that has lost 2 or more teeth by middle age usually has untreated periodontitis, not an accident. Dental X-rays from 18 months, then every 12 to 24 months, 400 to 900 dollars (2,880 to 6,480 yuan) including scaling, decide whether a tooth is saved or extracted; extraction of 1 tooth adds 80 to 250 dollars (580 to 1,800 yuan). After extractions, feed pate for 7 to 10 days and put water in 3 to 4 places, since a cat with fewer teeth drinks less that week. Do not file a missing tooth under ageing: the neighbour drifts and the opposite arcade overgrows within 12 to 18 months. Weigh monthly, because a cat that cannot chew well loses 5 percent of body weight before the owner notices the food bowl.
Skin: seborrhea and the folds
Less hair means more visible sebum, and the sebum is the substrate for yeast and bacteria. The routine is 5 minutes a week: wipe the neck, armpits, groin and the base of the tail with a soft cloth and warm water, then dry, then look. Bath every 7 to 14 days with a mild cat shampoo, and do not go under 7 days, since over-washing strips the barrier and produces more oil within 72 hours. Clean the outer ear canal weekly with a vet-approved cleaner, never with a cotton bud. Fold dermatitis is a red, moist, smelly line in a fold, and needs a cytology swab (45 to 95 dollars, 320 to 680 yuan) to separate yeast from bacteria before a cream. Steroid, antibiotic and oral antifungal products are by vet prescription only; a human antiseptic cream is a poor substitute.
HCM: echo at 12 months, then by the numbers
HCM is the third track and the one that kills without warning, so the echo is not optional. The cut-offs are the same ones used across breeds and set out in the Tonkinese plan: wall thickness under 5.0 mm is normal, 5.0 to 5.9 mm earns a recheck in 6 months, 6.0 mm or more needs a plan inside the week, and an LA/Ao above 1.5 is the second flag. No DNA test is validated for this breed, so the echo answers the question. Pay 220 to 450 dollars (1,580 to 3,240 yuan), repeat every 12 months, and after 3 clean scans move to 24 months. Ask for wall thickness, LA/Ao and any systolic anterior motion in writing. Beta blockers, calcium channel blockers and diuretics are vet decisions, by vet prescription only; human heart tablets are a hazard for a cat.
Blood, urine and the X-ray that earns its place
At 12 months, with the echo: a chemistry panel, a urinalysis with specific gravity, and a systolic blood pressure, 70 to 140 dollars plus 25 to 50 (500 to 1,010 yuan plus 180 to 360). Repeat yearly from age 7, and every 6 months from 10. One abdominal X-ray, 120 to 300 dollars (860 to 2,160 yuan), is worth it after 2 bladder episodes in a year; yearly films with no signs are not. Add T4 from age 8: a thin older cat with a good appetite is a thyroid question first.
4 signals you can check at home
Gum line: lift the lip weekly and look for a red margin, a dark edge of calculus, or a tooth sitting at a new angle. Breath: a metallic or rotten smell is gum disease, not a food effect. Skin: press a tissue into the fold behind the leg; grease plus a sour smell needs a cytology, not a stronger shampoo. Breathing: count chest movements for 30 seconds in deep sleep, twice a week, with 30 breaths a minute as the ceiling.
Call within these hours
| What you see | Call within | Why the clock is short |
|---|---|---|
| Open-mouth breathing at rest, or 40 breaths a minute | 0 to 1 hour | fluid in the lungs with a failing heart |
| Back legs cold, dragging, or sudden paralysis | 0 hours, emergency | a clot in the aorta, minutes matter |
| Face swelling with drooling, one side | 6 to 12 hours | a root abscess tracking into the cheek |
| A fold that is red, wet and smells, with fever | 12 to 24 hours | bacterial spread under the skin |
| No food for 24 hours plus hiding | 24 hours | fatty liver risk after 48 to 72 hours |
What it costs, in 2 currencies
| Item | When | USD | CNY |
|---|---|---|---|
| Visit with gum score and skin check | 6 months, then every 6 months | 60 to 120 | 430 to 860 |
| Dental X-ray, scale and polish | from 18 months, every 12 to 24 months | 400 to 900 | 2,880 to 6,480 |
| Extraction, per tooth | as needed | 80 to 250 | 580 to 1,800 |
| Skin or ear cytology | as needed, 1 to 3 times a year | 45 to 95 | 320 to 680 |
| Echo with blood and urine | 12 months, then yearly | 290 to 590 | 2,080 to 4,250 |
Yuan values hold 1 dollar at 7.2, so a clinic that quotes less is not quoting a shorter list. Book the dental X-ray and the echo in 1 anaesthetic slot and the saving is 1 sedation, usually 100 to 200 dollars (720 to 1,440 yuan).
5 steps for this month
- Score both gum lines 0 to 4 and write the probing depth in millimetres.
- Start daily brushing; if the cat refuses, do 3 times a week and add gel.
- Wipe the 4 fold areas with warm water, dry, then smell the cloth.
- Set the bath interval at 10 to 14 days and stop scrubbing the ears with buds.
- Book the 12 month echo and the 18 month dental film on 1 day.
None of this diagnoses. Periodontitis needs probing and a radiograph, seborrhea needs a cytology before a shampoo, HCM needs an echo. The honest limit: published breed-specific figures for the Donskoy are thin, so the numbers here come from general feline dental, dermatology and cardiology practice. What makes the calendar worth keeping is the baseline, taken at 12 months while the cat still looks perfect. For a second view of how the same baseline logic is applied, the Turkish Van plan is a useful comparison.

Frequently asked
How often should a hairless cat be bathed?
Every 7 to 14 days with a mild cat shampoo, and not more often. The coat is not there to hold sebum, so weekly wiping does most of the work, while washing every 2 to 3 days strips the skin barrier and triggers more oil production within about 72 hours.
Is a missing tooth in an older Donskoy normal?
Common, but not normal. Loss is usually the end point of untreated periodontitis, and the teeth on either side drift while the opposite arcade overgrows within 12 to 18 months. Ask for dental X-rays and a probing chart rather than accepting it as ageing.
What is the point of an echo if the cat seems fine?
HCM is silent until it is not, and the first sign can be open-mouth breathing or a clot. The 12 month echo gives a wall thickness and an LA/Ao to compare against, so a 5.0 to 5.9 mm reading becomes a 6 month recheck instead of a surprise.
