Three checks cover a LaPerm: an echocardiogram for hypertrophic cardiomyopathy (HCM) from 12 months, a dental exam every 6 months, and a coat-and-skin routine that gets under the curl every 2 to 3 days. The third one is not cosmetic. A rex-type coat carries less guard hair and traps sebum against the skin, so what looks like a grooming problem is often the first sign of seborrhea or a yeast overgrowth. Breed-level figures are not published, so the schedule below is a default and the evidence is limited.
Screen schedule: 4 tests, 5 age bands
| Age | Echo | HCM DNA | Chest X-ray | Urine | Skin check |
|---|---|---|---|---|---|
| 8 to 12 weeks | 0, listen only | 1, optional | 0 | 0 | 1, baseline |
| 12 months | 1 | 0, already run | 1, baseline | 1, baseline | 1 |
| 24 months | 1 | 0 | if murmur grade 2 of 6 | 1 | 1 |
| 2 to 7 years | 1 per 12 months | 0 | 1 per 24 months | 1 per 12 months | 1 per 6 months |
| 8 years and up | 1 per 6 to 12 months | 0 | 1 per 12 months | 1 per 6 months | 1 per 6 months plus cytology |
Year 1 holds 1 echo, 1 X-ray, 1 urine test and 2 skin exams, and the dental line runs alongside it: a conscious check every 6 months, with the first anesthetized scaling when tartar appears, usually between 2 and 4 years.
Heart: the same 3 numbers as any cat
HCM thickens the left ventricular wall with no pressure load to explain it. The report needs wall thickness in diastole (under 5 mm normal, 5 to 5.9 mm grey zone with a 6 month recheck, 6 mm or more meeting the standard definition), the left atrium to aorta ratio (1.5 or below fine, 1.5 to 1.7 equivocal, above 1.7 changing the plan within 7 days), and systolic anterior motion of the mitral valve, which points to a different drug class. A murmur at grade 2 of 6 is the trigger for a chest X-ray, where a vertebral heart score above 8.0 suggests enlargement against a typical 7.5.
The DNA panel covers the Maine Coon variant (MYBPC3 A31P) and the Ragdoll variant (MYBPC3 R820W). No LaPerm-specific variant has been established, so it returns 2 markers plus variants of unknown significance for 60 to 200 dollars, run once. A positive holds the echo at every 12 months for life; a negative does not clear the cat. The same limit shows up in other breeds, which is why the Tonkinese screening plan also treats a normal scan as a baseline rather than a verdict.
Teeth: why the echo comes before the scaling
Dental work in a cat with an unexamined heart is a risk decision, not a cleaning. That is why the 12 month echo comes first: an anesthetic plan for a cat with a 6 mm wall and a dilated atrium looks different from one for a cat with 4.6 mm. From age 1, a conscious oral exam every 6 months checks tartar on the upper fourth premolar, redness at the gum margin and whether the cat chews on 1 side. From age 3, or earlier if tartar shows, add an anesthetized examination with periodontal probing and full mouth radiographs, because 60 percent of the tooth sits under the gum.
Probing depth under 1 mm is normal in a cat, and 2 mm or more with bleeding means attachment loss. Grade 1 (tartar, no redness) waits 6 months; grade 2 (redness, bleeding on probing) is a scaling within 30 days; grade 3 or 4, with pus or a loose tooth, is within 7 days. At home, brush 3 times a week for 30 seconds a side. Analgesics and antibiotics after an extraction are prescription items, given on a veterinarian's order only.
Skin: what the curl hides
A rex coat has fewer guard hairs, so sebum, dead skin and yeast sit closer to the surface. Check 4 places every 2 to 3 days with your fingers, not just your eyes: behind the ears, the armpits, the groin and the base of the tail. What you are feeling for is greasiness, a sour smell, brown waxy debris in the ear canal, or a patch that feels like sandpaper. Greasy seborrhea and Malassezia overgrowth look similar to an owner and different under a microscope, which is why cytology (45 to 110 dollars, 10 minutes) comes before any shampoo choice.
Bathe every 4 to 6 weeks with a mild cat shampoo, and use a medicated one only when cytology names the organism; a medicated shampoo on dry skin makes the grease worse. Dry the coat fully, because a damp curl holds moisture against the skin for hours. Flea control is monthly all year, and a flea comb once a week catches an infestation before the itching starts. If scratching lasts more than 2 weeks with a normal skin scrape, the next step is an 8 week elimination diet, not a stronger shampoo.
The 4 signals to log at home
Resting respiratory rate, counted for 30 seconds in sleep and doubled: under 30 breaths a minute is normal, 30 to 39 on 2 separate days earns a call, 40 or more at rest is an emergency. Then weight in grams on the same scale, because a curly coat can hide 300 g. Then the skin score: 0 for clean, 1 for slight grease, 2 for grease plus smell, 3 for redness or broken skin, written down with the date. Then appetite and chewing, since a cat with a sore mouth drops kibble before it stops eating.
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 |
| Skin broken, oozing or bleeding | any open area | 24 hours | cone collar, no human ointment |
| Face or jaw swelling | any, with or without drooling | 12 hours | no pressure, no lancing |
| Refusing food 24 hours | 1 full day, or 12 hours with pain | 6 hours | note last stool, offer soft food |
| Scratching 2 weeks with no flea sign | 14 days of broken sleep | 7 days | start a foto log, book cytology |
What the first 2 years cost
US clinic ranges and mainland China ranges at roughly 7.2 CNY per dollar.
| Item | USD | CNY |
|---|---|---|
| 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 |
| Dental prophylaxis with radiographs | 300 to 700 | 2,200 to 5,000 |
| Year 1 total, first 5 items | 455 to 1,030 | 3,290 to 7,500 |
Year 2 runs 265 to 610 dollars with 1 echo, 1 urine test and 2 skin exams, plus 300 to 700 if the first dental lands then. Read the exclusions before buying cover, since dental cleaning and breed-linked screening are the 2 lines most often removed. Compare the Turkish Van plan and the breed quiz.
Five steps for this month
- Book the 12 month echo; ask for wall thickness, LA/Ao and SAM in writing.
- Add the HCM panel once, at that same visit.
- Start the 4 point skin check every 2 to 3 days and score it 0 to 3.
- Book a dental exam and get the first scaling priced before it is urgent.
- Weigh in grams and count the sleeping respiratory rate twice this week.

Frequently asked
How often should a LaPerm be bathed?
Every 4 to 6 weeks with a mild cat shampoo, and only with a medicated product when cytology names the yeast or bacterium. Rinse fully and dry the coat to the skin, because a damp curl holds moisture for hours. Between baths, run your fingers through 4 spots every 2 to 3 days and score the grease from 0 to 3.
Does a LaPerm need a heart scan before dental work?
Yes, and the 12 month echo is the practical baseline. Anesthetic planning for a cat with a 6 mm wall and a dilated atrium differs from a cat at 4.6 mm, and a grade 2 of 6 murmur is enough to add a chest X-ray before any scaling is booked.
What does seborrhea look like under a LaPerm coat?
Greasy skin at the ear base, armpit, groin or tail base, a sour smell, and brown wax in the ear canal, often with no visible redness at first. Cytology costs 45 to 110 dollars and separates seborrhea from a yeast overgrowth, which matters because a medicated shampoo on the wrong problem makes the skin drier.
