A Khao Manee is a small white cat with a tiny gene pool, and two facts shape everything: a share of the breed is born deaf, and white skin on ear tips and nose burns. Both mean the calendar gets built around an indoor cat that may not hear you coming.
The year at a glance
| Window | Coat, skin and face | Hearing, weight and health |
|---|---|---|
| January-February | Curry weekly; wipe tear stains daily | Monthly weigh-in; ears checked weekly |
| March-May | Twice weekly during the shed; nails every 3 weeks | Spring weigh-in; vet visit with ear and skin check |
| June-August | Weekly; check ear tips and nose for crusts | Keep sun off between 11 am and 4 pm; water in three rooms |
| September-October | Twice weekly; bathe if the coat looks grey | Autumn weigh-in; adjust food by 10 percent |
| November-December | Weekly; wipe the chin after wet food | Year-end weight, vaccine dates, parasite dose |
Hearing: test once, then manage
Deafness in this breed is congenital and tied to blue eyes. A cat with two blue eyes carries the highest risk, an odd-eyed cat is often deaf on the blue side only, and a cat with two non-blue eyes is usually hearing. The test is a BAER, run at 6-12 weeks or later, and it gives a yes or no per ear.
The house has to change. Never outdoors, not even in a garden, because a cat that cannot hear a car cannot avoid it. Wake it by touching the floor nearby or by switching a light on and off, never by looming over it. Teach hand signals for come, sit and no, plus a torch flash for recall.
White skin: the sun is the risk
Sun damage on white ear tips and the nose bridge is the breed's other real hazard, and squamous cell carcinoma is the end point. Indoor-only is the first rule; a screened balcony is fine if it is shaded. If it insists on a sunny window, fit UV film and keep the sill for mornings; the June-to-August sun from 11 am to 4 pm is what burns.
Check the ear tips and nose weekly with a thumb and forefinger: a dry crust that scabs, a pink spot that does not heal in 3 weeks, or a sore that bleeds when touched needs a vet, not ointment. Never use human sunscreen, because zinc oxide is toxic to cats, and never assume a "scab" on a white ear is from scratching.
Weight: the white coat hides everything
A compact, food-motivated cat that gains quietly, and the white coat hides the change.
- 3 months: 1.0-1.5 kg, four meals a day
- 6 months: 1.8-2.6 kg, three meals a day
- 12 months: 2.6-3.6 kg, two meals a day
- Adult female 2.7-3.5 kg; adult male 3.4-4.5 kg
- Daily: 1/3 to 1/2 cup dry (40-60 g) or 4-5 oz wet (115-140 g)
- Monthly weigh-in; 100 g is 3 percent of a 3.5 kg cat, so act early
Weigh on the same scale, at the same time, once a month, and write it down. A neutered Khao Manee thickens at the waist first, and by the time the shape reads as fat the cat is usually 500 g over.
Skin and coat through the year
The short coat has little undercoat and self-grooms well, so a rubber curry once a week is plenty. White shows dirt first at the chin, the chest and around the eyes, so a damp cloth daily on the face is worth more than a bath. Bathe every 8-12 weeks with a mild shampoo; whitening shampoos are harsh and often leave the coat drier and more yellow.
Tear staining is the cosmetic problem owners notice first. Wipe the tear line once a day with plain water, keep the face dry, and check whether the food has changed. If the staining starts suddenly with squinting or a red eye, that is a vet visit, not a grooming problem.
Ears, eyes and the small gene pool
There is no breed-wide hereditary disease beyond deafness, but the gene pool is genuinely small, which raises the value of screening the parents rather than the kitten. Ask for the BAER results of both parents, a recent echocardiogram, and a pedigree with the inbreeding coefficient shown. A breeder who has never tested hearing is guessing.
Check the ears weekly, because a deaf cat cannot show you an ear problem by tilting towards sound, and wax builds up in a small canal. Look for dark discharge, a smell, or scratching at the ear. Eyes get checked at every annual visit; redness on a white face is easy to see.
Play, height and a quiet corner
Two short sessions of 10-15 minutes a day plus a tall cat tree cover the exercise. A bored Khao Manee climbs curtains rather than sitting still, so vertical territory is not optional: shelves at 40 cm intervals, a perch at 1.5 m, and a window with a screen.
Give it a retreat too. A deaf cat cannot hear you coming, so a covered bed in a quiet corner, out of the traffic path, is where it goes to switch off.
Five mistakes that cost the most
- Letting a deaf cat outdoors, even briefly
- Skipping the BAER test and assuming the cat hears
- Free-feeding because the white coat hides the gain
- Putting human sunscreen on a white nose
- Bathing weekly to keep the coat bright
The outdoor one ends badly: a deaf cat cannot hear a car, a dog or a shout, and outdoor cats die years before indoor cats.
When to call the vet
Within 24 hours: a scab on an ear tip that has not healed in 3 weeks, 5 percent weight loss in a month, a week of loose stool, or an ear that smells. Immediately: a nose sore that bleeds, a cat that cannot pass urine, open-mouth breathing, pale gums, or a sudden head tilt with loss of balance. A deaf cat with a head tilt needs to be seen the same day, because the ear is the usual cause.
Twelve months, five habits
- BAER test once, then hand signals and a light flash for recall.
- Weigh monthly and write the number down.
- Curry weekly; wipe the face daily; bathe every 8-12 weeks.
- Check ear tips and nose weekly, and photograph any spot.
- Indoor only, with a UV film on the sunniest window.
Frequently asked
How do I know if my Khao Manee is deaf?
A BAER test gives a definite answer per ear, usually at six to twelve weeks but valid later too. Blue-eyed cats carry the highest risk, odd-eyed cats are often deaf on the blue side only, and cats with two non-blue eyes usually hear. Watching for a startle response is unreliable, because a deaf cat feels floor vibration and will turn towards a door slam. Test once and keep the result with the vaccination record.
Can a white Khao Manee go outside?
Indoor-only is the safer default for two reasons. White ear tips and the nose bridge burn easily, and squamous cell carcinoma is the end point of repeated damage. A deaf cat also cannot hear traffic, dogs or warnings. If you want outdoor time, use a shaded, screened catio rather than a garden, and fit UV film to the sunniest window. Never apply human sunscreen, because zinc oxide is toxic to cats.
Why does my Khao Manee keep gaining weight?
The white coat hides body condition, so a compact cat can gain half a kilogram before the shape looks any different. Weigh monthly on the same scale and act at one hundred grams, which is about three percent of body weight. Feed two measured meals of one third to one half cup of dry food or four to five ounces of wet food, and put the bowl away between meals instead of leaving it down.
