A Khao Manee needs 3 screens and 1 of them is time critical: a BAER hearing test at 6 to 8 weeks, a skin exam twice a year for sun damage on white ears and a pink nose, and a monthly weigh-in. The hearing test comes first because a deaf kitten needs a different room, a different recall signal and a different outdoor rule from the day it arrives. Breed-wide figures are not published for this breed, so the intervals below come from white-cat screening practice and should be read as evidence limited.
Screen schedule: hearing first, then 4 annual lines
| Age | BAER | Echo | HCM DNA | Chest X-ray | Urine |
|---|---|---|---|---|---|
| 6 to 8 weeks | 1, both ears | 0 | 1, optional | 0 | 0 |
| 12 months | 0, repeat if unclear | 1 | 0, already run | 1, baseline | 1, baseline |
| 24 months | 0 | 1 | 0 | if murmur grade 2 of 6 | 1 |
| 2 to 7 years | 0 | 1 per 12 months | 0 | 1 per 24 months | 1 per 12 months |
| 8 years and up | 0 | 1 per 6 to 12 months | 0 | 1 per 12 months | 1 per 6 months |
Two lines sit outside that table: a full skin exam every 6 months from age 1, and a home check of the ear tips and nose every 30 days. The echo is a baseline, not a breed verdict, because a Khao Manee with no murmur at 12 months can still develop wall thickening at 6 years.
Hearing: BAER, one ear at a time
Congenital sensorineural deafness runs in white cats, and the odds rise with 2 blue eyes rather than 1 or none. BAER delivers 60 to 90 dB clicks through a foam insert into each ear, with 3 electrodes on the scalp, and prints a separate waveform for the left and the right side in 10 to 15 minutes. That separation is the whole point. A cat deaf on one side hears a call from the front and nothing from the blind side, so it looks obedient in the kitchen and unreachable in the garden.
Book the test at 6 to 8 weeks, once the ear canals are open, at 60 to 150 dollars; general practices usually refer. Home tests are weaker than owners hope: keys shaken 1 m behind a sleeping kitten catch near-total deafness and miss 1 dead ear completely. If a ear fails, change 3 things the same week: no free roam, approach always from the hearing side, and a bell on the resident cat. Deaf cats read hand signals and floor vibration well, and a stomp at feeding time replaces a shout.
Skin: the white ear tip is the risk site
Sun damage in this breed concentrates where hair is thin and skin is unpigmented: the ear tips, the nose leather, the eyelids and the white muzzle. Chronic exposure shows as redness, then scaling, then a crust that will not heal; a lesion that persists past 14 days is the point where a vet looks at cells rather than at the surface. Screening is a full skin exam every 6 months from age 1, with the ears flipped and the nose photographed under the same light each time, since a 2 mm change is easier to spot against a photo than against memory.
Cytology costs 45 to 110 dollars and takes 10 minutes; a biopsy with histopathology runs 150 to 400 dollars and needs sedation. Do not use human sunscreen or any product containing zinc oxide, which a cat licks off and swallows. Shade, UV-blocking window film on the sunny window, and keeping the cat indoors between 10:00 and 16:00 do more than any cream. In summer, a cat that naps on hot paving at 13:00 is collecting UV on its nose and heat on its pads at the same time.
Weight: small frame, fast gain
A Khao Manee sits near 2.5 to 4 kg, so 300 g is a visible change and 400 g is a 10 percent gain on a 4 kg cat. Weigh monthly on a baby scale readable to 5 or 10 g, same hour, before the morning meal, and score body condition on the 9 point scale: 5 is ideal, 6 to 7 is 5 to 10 percent over ideal, 8 and 9 is obesity. Treats above 10 percent of daily calories is where most gain starts; for a cat eating 200 kcal a day, that is 20 kcal, or 4 or 5 small treats.
For loss, aim at 0.5 to 1 percent of body weight per week, which is 15 to 40 g on a 3.5 kg cat, and never faster than 1.5 percent, because a cat that stops eating for 48 hours is at risk of hepatic lipidosis. Weigh weekly while losing, monthly once stable.
The 4 signals to log at home
First, sound response behind the head, tested at 6 weeks with a soft clap at 2 m, never in front of the face. Second, any crust, scab or ulcer on an ear tip or the nose that lasts 14 days. Third, weight in grams and body condition score, logged the same day each month. Fourth, sleeping respiratory rate, counted for 30 seconds and doubled, because a white cat with a heart murmur needs both numbers in the same note.
When to call, by the hour
| Sign | Threshold | Call within | First move |
|---|---|---|---|
| Sleeping respiratory rate | 40 or more, or 30 to 39 twice in 24 hours | 2 hours | 30 second video, then drive in |
| Open-mouth breathing at rest | any episode past 60 seconds | 0, now | carrier, cool car, no scruffing |
| Ear tip or nose ulcer, bleeding | any active bleeding | 24 hours | clean saline, cone collar, no cream |
| Crust or sore lasting 14 days | 1 lesion, no healing | 7 days | photograph daily, book cytology |
| No response to sound at 8 weeks | 2 tests, 2 days apart | 7 days | book BAER, both ears |
| Weight up 10 percent in 3 months | 0.4 kg on a 4 kg cat | 7 days | weigh weekly, cut treats first |
What the first year costs
US clinic ranges and mainland China ranges, at roughly 7.2 CNY per dollar. Specialty centers sit at the top of each band.
| Item | USD | CNY |
|---|---|---|
| BAER, both ears | 60 to 150 | 430 to 1,080 |
| Echocardiogram | 220 to 450 | 1,600 to 3,300 |
| HCM DNA panel, once | 60 to 200 | 430 to 1,450 |
| Chest X-ray | 90 to 180 | 650 to 1,300 |
| Urinalysis | 40 to 90 | 290 to 650 |
| Skin cytology | 45 to 110 | 320 to 790 |
| Biopsy with histopathology | 150 to 400 | 1,080 to 2,900 |
| Year 1 total, all 7 | 665 to 1,580 | 4,800 to 11,400 |
Year 2 runs 260 to 570 dollars for an echo, a urine test and 2 skin exams, and drops the BAER and the DNA panel entirely. See the Tonkinese plan for the same tests and the breed quiz if the lines are unclear. Prescription drugs, including a beta blocker if wall thickening is confirmed, come from a veterinarian only. Any topical for a sun lesion is also prescription strength, because steroid creams thin already damaged skin.
Five steps for this month
- Book BAER for 6 to 8 weeks and ask for a left and right result in writing.
- Photograph both ear tips and the nose today, then every 30 days under the same light.
- Fit UV window film on the 1 window the cat uses most.
- Start a monthly weigh-in in grams and a body condition score out of 9.
- Set a 10:00 to 16:00 indoor rule for June through August.

Frequently asked
When should a Khao Manee kitten have its hearing tested?
At 6 to 8 weeks, once the ear canals open, with BAER delivering 60 to 90 dB clicks to each ear and reporting them separately in 10 to 15 minutes. The cost is 60 to 150 dollars. A kitten that turns toward a doorbell can still be deaf on 1 side, and only the clinic test separates the two.
How do I protect a white Khao Manee from sun damage?
Shade, UV-blocking film on the sunny window, and no outdoor time between 10:00 and 16:00 from June through August. Check ear tips, nose and eyelids every 30 days and photograph them under the same light. A lesion that lasts 14 days needs cytology, and any bleeding sore needs a visit within 24 hours.
What weight is healthy for a Khao Manee?
Most sit between 2.5 and 4 kg with a body condition score of 5 out of 9, judged by ribs and waist rather than the number alone. Weigh monthly in grams before the morning meal, because 400 g on a 4 kg cat is already a 10 percent gain that calls for a vet visit.
