A Himalayan plan runs on 3 clocks. Kidneys and heart: echo and kidney panel every 12 months from age 1. Eyes: a dilated exam every 12 months. Teeth: a full mouth check every 6 to 12 months, with films. Two items are one-time DNA swabs, the PKD1 test and the PRA variant test; the rest is hands, ultrasound, X-ray and a microscope. The flat face drives the last 2 clocks, and both are managed by watching specific things at home.
The screen: 5 items on 3 clocks
| Item | First at | Repeat | Cost (USD) | Finds |
|---|---|---|---|---|
| PKD1 DNA swab | any age, once | never | 70 to 140 | dominant cyst gene |
| Kidney ultrasound | 12 months | every 12 months to 3 years, then every 24 | 150 to 350 | cysts, kidney size |
| Echocardiogram | 12 months | every 12 months | 250 to 500 | wall thickness, LA/Ao |
| Eye exam, dilated | 12 months | every 12 months | 100 to 200 | retinal degeneration |
| Dental films plus cleaning | 12 months | every 6 to 12 months | 400 to 900 | crowding, resorption |
Add urine specific gravity and SDMA to the kidney clock at 45 to 90 and 40 to 70 dollars, plus blood pressure from age 7 at 30 to 60 dollars. The yearly visit carries 4 of the 5 items, and the echo runs on the same 12 month rhythm as the Maine Coon heart protocol.
Kidneys: PKD swab first, ultrasound at 12, 24 and 36 months
Polycystic kidney disease (PKD) is autosomal dominant in this breed family, which makes the DNA test unusually useful: 1 copy means the cat will develop cysts, and a clear cat does not pass it on. The swab costs 70 to 140 dollars and never repeats. Ultrasound does the rest, because a positive swab does not date the disease. Cysts are often too small to see before 10 months, so the scan at 12 months is a baseline and the scans at 24 and 36 show growth. Ask for kidney length in cm, cyst count per kidney, and the largest cyst in mm; a kidney over 4.5 cm, or a cyst crossing 10 mm, moves monitoring to every 6 months. Bloodwork every 12 months includes creatinine, SDMA and urine specific gravity, because SDMA rises first and a USG under 1.030 on a repeat means concentration is going. No drug removes cysts; anything given for nausea, proteinuria or hypertension comes from an antiemetic, an ACE inhibitor or a calcium-channel blocker class, by veterinary prescription only.
Eyes: what the swab cannot see
Progressive retinal atrophy (PRA) starts in the rods, so the first owner-visible sign is night blindness: the cat hesitates at a dark doorway or stops jumping onto a familiar chair after lights out, and the pupil stays dilated. A DNA test covers the variant available for the breed, and a clear result is worth having, but other forms of PRA have no test. That is why the dilated exam stays annual from 12 months, and why a cat that fails a dim-light maze gets an electroretinogram at 250 to 400 dollars instead of another wait. There is no treatment; keep the cat indoors, keep furniture in place, and flag the eyes before any anesthesia.
Airway: 6 things to watch in a flat-faced cat
Brachycephalic airway syndrome is a package: narrow nares, an elongated soft palate, sometimes a hypoplastic trachea. Watch 6 things. 1: nostril flare with breathing audible from 2 m at rest. 2: snoring that wakes the cat. 3: open-mouth breathing at 24 to 26 C, a temperature a normal cat tolerates. 4: play tolerance under 5 minutes, or a cough after 2 minutes. 5: retching or bringing up food 1 to 2 hours after eating, which points at the soft palate. 6: gums going grey during excitement. Any 2 of the 6 for 2 weeks means an airway exam under light sedation plus a chest X-ray at 120 to 240 dollars; nares surgery with a palate trim runs 800 to 2,000 dollars, and earlier is less irreversible. Keep the room at 26 C or below, walk on a harness, and hold body condition at 5 of 9, because 500 g of fat on a 4 kg cat loads every breath, and the weight trend chart catches it early.
Teeth: crowded by design, cleaned on a schedule
A shortened jaw crowds the arcade, so watch 4 things: incisors that overlap or sit in 2 rows, a lower canine indenting the palate, premolars rotated out of line, and a 1 to 3 mm overbite or underbite that changes how the cat picks up food. Retained baby teeth at 6 months are common and should come out at the spay. Full-mouth films at every cleaning are not optional here, because resorption hides under 2 mm of calculus and below the gum line. A cleaning with films runs 400 to 900 dollars, an extraction 600 to 1,400, and daily brushing with a 0.5 cm ribbon of pet toothpaste prevents most of it. Dropping food, chewing on 1 side, drooling, or pawing the mouth move the appointment forward.
4 signals to log at home
- Resting breaths: 30 seconds counted, 30 per minute is the sleep ceiling.
- Noise: breathing audible 2 m away, or snoring that wakes the cat.
- Water and urine: a bowl emptied twice as fast, clumps twice the size.
- Weight: 5 percent in 3 months is 200 g at 4 kg, enough to change the airway plan.
The hour-level call table
| Signal | Threshold | Call within | Why |
|---|---|---|---|
| Open-mouth breathing at rest | any | 0 to 1 hour | airway obstruction |
| Grey or blue gums | any | 0 to 1 hour | hypoxia |
| Panting in a 26 C room | over 5 minutes | 1 hour | heat intolerance |
| Collapse after excitement | any | 0 to 2 hours | syncope, airway or heart |
| Sleeping respiratory rate | 30 or more, 3 in a row | 24 hours | echo within 7 days |
| Not eating after dental work | 24 hours | 24 hours | pain or flap problem |
| Facial swelling under 1 eye | any | 24 hours | tooth root abscess |
| Urine output doubling | 2 days in a row | 48 hours | concentration loss |
Costs, and the 2 items to refuse
A first year with all 5 items runs 900 to 1,900 dollars; years 2 and 3 run 600 to 1,300. Refuse 2 things: a breeder who will not show the PKD1 result of both parents, and a clinic that will clean teeth without films. The kidney ultrasound is what owners postpone when the swab is negative, and that is backwards, because not every cyst in this breed family is PKD1. The eye exam is the same logic: it costs less than the ERG it prevents.
5 steps for the next 30 days
- Send the PKD1 and PRA swabs together, 140 to 280 dollars for both.
- Book the 12 month visit with echo, kidney scan and eye exam in 1 day.
- Time the resting breath count twice this week in a 26 C room.
- Start brushing with a 0.5 cm ribbon, 5 nights out of 7.
- Put the food bowl on the floor and swap the collar for a harness.
None of this is a diagnosis. Cysts are counted on ultrasound, retinal disease is seen by an ophthalmologist, and the airway is graded under sedation. The plan changes when those happen: a cat examined at 12, 24 and 36 months has kidney size and an airway grade already on file.

Frequently asked
If the PKD1 swab is negative, can I skip the kidney ultrasound?
No. A negative swab lowers the odds a lot, but not every cyst in this breed family comes from the PKD1 variant, and the scan at 12 months is also the baseline that later scans are compared against. Most vets repeat it at 24 and 36 months and then every 24 months.
What are the first signs of an airway problem in a flat-faced cat?
Breathing you can hear from 2 m away at rest, snoring that wakes the cat, open-mouth breathing at 24 to 26 C, play tolerance under 5 minutes, bringing up food 1 to 2 hours after eating, and gums going grey with excitement. Two of those for 2 weeks justifies an airway exam.
Why do dental cleanings need X-rays in this breed?
Because a shortened jaw crowds the arcade and rotated or overlapping teeth trap calculus below the gum line, where resorption and root disease start. Films add 100 to 200 dollars to a 400 to 900 dollar cleaning and change the extraction plan before a tooth is lost.
