Two of the three problems that matter in an Asian Tabby are inherited from the Burmese lines behind the breed: familial episodic hypokalemia, which shows up as sudden weakness, and a craniofacial defect of the skull that is present at birth. The third, diabetes, arrives later and follows body condition. The plan below puts a potassium baseline at 6 and 12 months, a skull X-ray inside the kitten window, an echo at 12 months, and urine from age 2. Year 1 runs about 400 to 700 dollars, or 2,880 to 5,040 yuan at 7.2.
Why the potassium sample comes first
Familial hypokalemia in Burmese-derived cats behaves as episodes, not as one permanent number: a cat that is normal for 6 weeks and then cannot lift its head for 2 days. So the test that matters is a baseline drawn while the cat is well, at 6 months and again at 12 months, then once a year, plus 1 sample within 24 hours of any weak spell. Most labs print a reference interval near 3.5 to 4.5 mmol/L. A value under 3.0 mmol/L in a cat that cannot jump is a same-day call; 3.0 to 3.4 is a recheck in 7 to 10 days with the sample handled identically, because a delayed sample and a real low value read alike. Ask for the number, not the word normal. Potassium gel, powder and potassium-sparing drugs are prescription items, by vet prescription only: supplementing a cat whose potassium was never measured hides the next episode instead of preventing it.
The 6 and 12 month visit, 4 tests in 30 minutes
Both visits carry the same 4 items: potassium with a chemistry panel (25 to 45 dollars, 180 to 320 yuan), a urinalysis with specific gravity (30 to 60 dollars, 220 to 430 yuan), a systolic blood pressure (25 to 50 dollars, 180 to 360 yuan), and a body condition score written out of 9. Specific gravity is the cheap early warning: a cat concentrating to 1.050 is managing water, while 3 readings stuck between 1.020 and 1.030 point at a kidney that has stopped concentrating. That is a 3 visit trend, not a diagnosis on visit 1. Photograph every printout.
Skull: the X-ray belongs at 8 to 12 weeks
The craniofacial defect described in Burmese lines is congenital, so the useful window is 8 to 12 weeks, not 8 months. Ask for a skull radiograph (80 to 150 dollars, 580 to 1,080 yuan) if the forehead reads flat, if the eyes sit wider than the muzzle suggests, or if the kitten breathes through the mouth at rest. One normal film at 12 weeks is a film for life. What you are buying is a decision: a kitten with a flat skull plus any trouble nursing, swallowing or breathing between 6 and 10 weeks needs a vet the same day, and an affected kitten is the reason not to repeat that pairing.
Echo, urine and the DNA question
An echo at 12 months sets the heart baseline, since HCM runs in this family of breeds the same way it does in the Tonkinese, whose wall thickness cut-offs are laid out in the Tonkinese screening plan: 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. Pay 220 to 450 dollars (1,580 to 3,240 yuan), ask for wall thickness, LA/Ao and SAM in writing, repeat every 12 months to age 6, then every 24 months after 3 clean scans. Urine from age 2, once a year: glucose, protein, specific gravity, with a UPC added if protein is positive. Diabetes screening starts at 7 years, or at 3 years for a cat scoring 7 of 9 or above: fasting glucose plus fructosamine (45 to 90 dollars, 320 to 650 yuan), because 1 high glucose in a frightened cat is not diabetes and fructosamine reports 2 to 3 weeks instead of 1 minute. On DNA tests, do not buy first: published breed-specific data for the Asian Tabby is limited, so a marketed test is a question for the lab, not a result to act on.
4 signals you can check at home
Neck: watch the walk to the food bowl. A head that dips below the shoulder blades and a cat that sits instead of jumping is the weak-neck picture, and the hour it started is the number the vet will ask for. Water: over 45 ml per kg per day, which is 225 ml for a 5 kg cat, measured by filling a marked jug once a day. Weight: monthly on the same scale, since a 5 percent drop across 8 weeks vanishes under a tabby coat. Litter: count clumps. Going from 3 clumps a day to 6 bigger ones is a reason to book, not to change litter brand.
Call within these hours
| What you see | Call within | Why the clock is short |
|---|---|---|
| Head held low, will not jump | 0 to 2 hours | hypokalemia or a neurologic cause |
| Open-mouth breathing at rest | 0 to 1 hour | fluid in the lungs, heart or airway |
| Straining in the box, no urine for 12 hours | 4 to 6 hours | a blocked male can die in 24 to 48 hours |
| Kitten not nursing, 6 to 10 weeks | 0 to 4 hours | dehydration in a 500 g kitten is hours, not days |
| No food for 24 hours plus hiding | 24 hours | fatty liver risk climbs after 48 to 72 hours |
What it costs, in 2 currencies
| Item | When | USD | CNY |
|---|---|---|---|
| Kitten visit plus skull X-ray | 8 to 12 weeks | 140 to 270 | 1,010 to 1,940 |
| Potassium plus chemistry | 6 and 12 months, then yearly | 25 to 45 | 180 to 320 |
| Echo | 12 months, then yearly | 220 to 450 | 1,580 to 3,240 |
| Urinalysis, UPC if protein positive | from 2 years, yearly | 30 to 95 | 220 to 680 |
| Glucose plus fructosamine | from 7 years, yearly | 45 to 90 | 320 to 650 |
Yuan figures use 1 dollar at 7.2 as a constant, so a clinic that quotes lower is not quoting a different test. If the cat came without papers, spend 5 minutes on the breed quiz first. Three items to skip: annual chest films on a cat with no cough, a DNA panel with no validated variant for this breed, and supplements bought before a baseline exists.
5 steps for this month
- Book the 6 month potassium draw and ask for the number in writing.
- Weigh the cat today and start a monthly line in a notebook, out of 9 for body condition.
- Measure daily water with a jug for 3 days, so 225 ml has a reference.
- Photograph the last 3 lab printouts into 1 folder, sorted by date.
- Time how long the cat takes to reach the bowl and note any dip of the head.
Nothing here diagnoses. Hypokalemia needs a measured value, a skull defect needs imaging, diabetes needs 2 tests on different days. Be honest about the size of the evidence: this is a numerically small breed, breed-specific published figures are thin, and most of this plan is borrowed from Burmese and Tonkinese work plus ordinary feline preventive care. A calendar built around different priorities is the Turkish Van plan. The calendar still earns its keep, because a 12 month baseline taken while the cat looks perfect is the cheapest baseline you will ever own.

Frequently asked
How often should an Asian Tabby have potassium checked?
A baseline while the cat is well at 6 months and again at 12 months, then once a year, plus one extra sample within 24 hours of any weak spell. The baseline is what makes an episode readable, since a low value during weakness can also come from a delayed or haemolysed sample, and the two are handled differently.
Is a flat forehead in a kitten an emergency?
Only with a second sign. A flat or wide skull on its own is imaged at 8 to 12 weeks with a radiograph and often needs nothing. Trouble nursing, swallowing or breathing between 6 and 10 weeks is a same day visit, because a 500 g kitten dehydrates in hours rather than days.
Does the breed have a validated DNA test?
Treat that as unproven. Published breed-specific data for the Asian Tabby is limited, and a panel that names no variant validated in this breed answers a different question. Spend the money on the 12 month echo, the potassium baseline and the urine trend first, and ask any lab which variant it reports.
