Three of the 4 Somali risks are settled by a test you run once, and 1 runs on a calendar: the dental clock starts at 12 to 18 months, well before most owners book a first cleaning. The plan is 4 items, 2 DNA swabs for PK deficiency and rdAc retinal degeneration, a yearly oral exam with full-mouth radiographs whenever the cat is cleaned, and a urine protein to creatinine ratio (UPC) from age 2. Budget 450 to 750 dollars for year 1, 300 to 500 dollars a year after that, plus 300 to 700 dollars each time the teeth are scaled.
Teeth first, genes second
Early-onset gingivitis changes life soonest, and it is visible at 12 months: a red line at the gum, metallic breath, a brown edge on the upper fourth premolar. Brush 3 times a week minimum, daily if tolerated, with a soft brush and enzyme paste, plus 0.12 percent chlorhexidine gel twice a week. Every visit includes probing 6 sites per tooth; cleaning includes full-mouth radiographs under anesthesia, because 60 percent of the tooth sits under the gum. Grade 1 means gingivitis only and gets a cleaning at 12 months; grade 2 means up to 25 percent attachment loss and gets a cleaning now, not in 6 months. Pain control is a cat-specific nonsteroidal, by prescription only; human ibuprofen or paracetamol is toxic, as the toxicity checker lists.
The 2 swabs, and when 1 test is enough
PK deficiency is a recessive PKLR variant: 2 carriers produce affected kittens, and a carrier never needs a second test. rdAc is a rod-cone degeneration, also recessive, and in Abyssinian lines the causal variant is well enough described that a commercial swab is available. Test the parents before mating, or the kitten once at purchase, for 60 to 140 dollars each or 120 to 200 dollars for a panel, with results in 10 to 21 days. A kitten from 2 tested clear parents needs no further swab, only the calendar. A confirmed PK cat gets a CBC every 6 to 12 months and a line in the anesthesia file; a confirmed rdAc cat gets the house layout changed in the same month, while the retina still works at the edges.
The calendar by age
| Age | Oral exam | Blood and urine | Eye exam | Interval (months) | Cost USD |
|---|---|---|---|---|---|
| 12 months | 1, with probing | CBC, UPC, chemistry | 1 | 6 | 420 |
| 18 months | 1, cleaning if grade 1 or more | UPC | 0 | 6 | 650 |
| 24 months | 1 | CBC, UPC, SDMA | 1 | 12 | 380 |
| 3 to 6 years | 2 per year | UPC twice a year | 1 per year | 6 | 500 |
| 7 years and up | 2 to 3 per year | UPC and blood pressure every 6 months | 1 per year | 6 | 560 |
Two intervals are shorter than owners expect: teeth move faster here, so the oral exam is every 6 months, and the UPC repeats every 6 months because 1 normal value is a snapshot, not a clearance. Add 1 baseline echo at 12 months, 20 to 30 minutes at 220 to 450 dollars, so a murmur at 8 has a wall thickness to be compared against.
Retina: a 30 second test at dusk
rdAc takes the rod cells first, so dim-light vision goes before daylight vision, and a familiar house hides it until the pupils stay wide at dusk. Run 2 checks at home: drop a cotton ball from 30 cm in a dim hallway and watch whether the cat tracks the fall, and check that the pupils shrink when you shine a phone light from 20 cm. At the clinic, the dilated fundus exam looks at the tapetal reflex and the retinal vessels, and an electroretinogram (ERG) gives a functional number in about 30 minutes under sedation for 250 to 450 dollars. Book the exam yearly from 12 months, every 6 months after a change, and treat the house as part of the plan: night lights, no furniture moved, food and water in the same 2 spots.
Kidneys: the 1 number most owners never get
Renal amyloidosis is a protein-folding problem, not an infection, and it shows as urine protein long before the blood chemistry moves. That is why the UPC is the test to insist on: under 0.2 is normal, 0.2 to 0.4 is borderline and earns a repeat in 4 weeks, and above 0.4 is proteinuria that needs a plan. Collect the sample at home to avoid a stress-related rise: empty the box, use non-absorbent beads, and get the sample to the clinic within 2 hours or refrigerate it. Add SDMA and a systolic blood pressure reading, where 160 mmHg is the usual ceiling, at the same visit. A UPC of 0.5 that repeats at 0.6 across 4 weeks is a different animal from a single 0.5 after a car trip.
4 signals you can check at home
Gum line: lift the lip weekly and look for the red border moving up the tooth. Breath: a metallic or sweet smell is the earliest dental sign, and it precedes visible tartar by months. Night route: does the cat cross the room at 30 minutes past sunset the same way it does at noon. Water and weight: above 45 ml per kg per day, or a 5 percent weight loss in 8 weeks with a good appetite, both point at the kidney, so log them in a weight trend chart.
Call within these hours
| What you see | Call within | Why the clock matters |
|---|---|---|
| Drooling, pawing the mouth, refusing food | 12 to 24 hours | abscess or a fractured tooth with pulp exposure |
| Gums pale or grey, cat weak | 0 to 1 hour | anemia from red cell loss needs blood work now |
| Open-mouth breathing at rest | 0 to 1 hour | fluid in the lungs or heart failure |
| Straining in the box with no urine | 4 to 6 hours | blockage can kill within 24 to 48 hours |
| Sudden blindness, bumping into walls | 24 hours | retinal detachment or high blood pressure |
What the bills actually look like
A cleaning with radiographs and anesthesia runs 300 to 700 dollars; extractions add 80 to 200 dollars per tooth, and 3 or more teeth removed lands at 600 to 1,200 dollars. The DNA panel is 120 to 200 dollars once, the UPC 35 to 70, an eye exam 90 to 180, an ERG 250 to 450. Put 40 dollars a month aside from the kitten year, and the 18 month cleaning stops being an emergency.
5 steps for this month
- Start brushing tonight, 3 sessions a week, and mark them on a calendar.
- Ask for the parents' PK and rdAc swab results in writing before a deposit.
- Book the 12 month visit with oral probing, CBC and UPC, 380 to 450 dollars.
- Run the cotton ball test at dusk this week, and write down what you saw.
- Switch the litter box to beads for 1 collection day, so the UPC sample is easy.
Screening does not treat anything here. The swabs say what the cat inherited, the probe says what the gum is doing, and the UPC says what the kidney is leaking. A Somali with 3 years of clean values and a dental cleaning at 18 months is a cat whose first crisis has a baseline to be measured against.

Frequently asked
Why does a Somali need a dental check before its first birthday?
Because early-onset gingivitis in this line shows up as a red border at the gum line by 12 months, and probing 6 sites per tooth finds attachment loss months before tartar is visible. A grade 1 mouth gets a cleaning at 12 months and a home brushing routine of 3 sessions a week; a grade 2 mouth with up to 25 percent attachment loss gets cleaned the same month.
How often should the UPC be repeated?
Every 6 months from age 2, and at every senior visit after 7. Under 0.2 is normal, 0.2 to 0.4 is borderline and earns a repeat in 4 weeks, and above 0.4 means proteinuria that needs a plan. Collect the sample at home with non-absorbent beads, since a car trip and a full bladder can push a single reading up.
Do the PK and rdAc swabs need repeating?
No. PK deficiency and rdAc are both recessive, so 1 test per cat is enough, and a clear kitten from 2 tested clear parents needs no swab at all. What does repeat is the monitoring: a confirmed PK cat gets a CBC every 6 to 12 months, and a confirmed rdAc cat gets an eye exam every 6 months plus a changed house layout.
