An Abyssinian stays lean without help and hides kidney disease until most of the function is gone, so the two habits that matter are weighing and urine testing. Coat work is almost nil; the calendar is mostly about the mouth, the eyes and the kidneys.
Baselines: 3.5-4.5 kg for males and 3.0-4.0 kg for females, 200-250 kcal a day at 4 kg, an eye exam and a PCV at 12 months, a urine protein:creatinine ratio at 2 years, and a gum check every week.
What the breed actually asks of you
Four systems need dates in the year: kidneys (familial amyloidosis), eyes (progressive retinal atrophy), blood (pyruvate kinase deficiency) and gums (periodontal disease, which is close to universal by middle age). Everything else is maintenance.
The cat will not help. Abyssinians lose weight on the kidneys before they look sick, and they keep eating with painful gums. Measurement is the only early signal you get, which is why a 50 RMB baby scale earns its place more than any toy.
Coat and mouth: five minutes a week, three brushings
Five minutes a week using a rubber curry, or a chamois wrung out in warm water, lifts the small amount of dead hair this coat produces and spreads skin oil along the shaft. Real brushing is almost pointless here, and a bath every 2-3 months covers it; with no down layer worth mentioning, tangles barely happen.
The mouth is the real work. Brush three or four times a week for 30 seconds a side, and look at the gum line weekly: a thin red border along the teeth is gingivitis, and in this breed it progresses to periodontitis faster than in most shorthairs. Professional scaling from age 2, then every 12 months if tartar returns. Ear checks are weekly work, since big ears trap dark wax, and nails every 2 weeks.
Weight: keep it lean, keep it stable
Adult males land at 3.5-4.5 kg, females at 3.0-4.0 kg; a body condition score of 4-5 out of 9 with a visible waist and a thin fat layer over the ribs is the target. Weigh monthly, and every 2 weeks from age 7 or after any illness, because loss is the first sign of amyloidosis.
At 4 kg an active adult needs 200-250 kcal a day, spread across two or three meals. Leaving a full bowl down is a mistake here even though the cat looks thin: it holds 240 kcal and gains on 300. A 10% loss over 3 months, about 350-400 g, is a vet visit with bloodwork and a urine ratio, not a portion increase. A 5% gain over 8 weeks means cutting 10% of the ration.
| Age | Test | Why |
|---|---|---|
| Any age | PRA and PK DNA tests | One swab, decides breeding and gives a baseline |
| 12 months | Fundic eye exam, PCV, first dental exam | Retinal changes and anaemia are both silent early |
| 2 years | Urine protein:creatinine ratio, then yearly | Amyloidosis shows in protein before creatinine moves |
| 3-6 years | Eye exam yearly, dental scaling every 12 months | PRA and periodontal disease both accelerate here |
| 7 years + | Annual panel, UPC, blood pressure, SDMA | Kidney function and thyroid, twice-yearly if abnormal |
Screening calendar for the three inherited risks
Progressive retinal atrophy (PRA) has a DNA test and a clinical exam; most ophthalmologists see breeding cats at 12 months, then yearly, and pet cats at 12 months and every 1-2 years to age 6. In dim light, hesitation at a stair, or a cat that walks into the furniture, means an appointment within a week.
Pyruvate kinase (PK) deficiency is diagnosed by DNA plus a blood count: a PCV below 20% or pale gums with lethargy is an emergency within 24 hours, while a PCV of 20-28% needs a workup that week. Renal amyloidosis is tracked by the urine protein:creatinine ratio: under 0.2 is normal, 0.2-0.4 is repeat in 4 weeks, above 0.4 means a vet visit with blood pressure and imaging. From age 2, run it once a year; from age 7, twice.
Food, water and the kidney argument
Protein at 40-45% of dry matter is fine for a healthy Aby, but once the urine ratio is abnormal, the plan changes and a vet sets the target rather than a bag. Wet food daily is the cheapest kidney protection available: this breed drinks ordinary amounts, and 4 kg of cat needs 150-220 ml a day. Two or three meals suit its fast metabolism better than one large meal.
Treats stay under 10% of calories, about 20 kcal. Sudden diet changes cause loose stool in this breed, so any switch runs 10 days in 25% steps, and new proteins go in one at a time.
Exercise: short bursts, high intensity
Two 20-minute wand sessions a day is the floor, plus a puzzle feeder and vertical space. Abyssinians want novelty: rotate toys weekly, keep two or three out at a time, and let the cat work for part of its food. Add a wheel in the hallway, or a harness walk, for real mileage.
Height and a window with a bird feeder will keep it busy for hours. Secure screens - this is a cat that will test an open window at speed.
Five mistakes that cost the most
- Assuming thin means healthy and never weighing.
- Waiting for symptoms before the first urine ratio at age 2.
- Skipping tooth brushing because the cat eats fine - gum pain rarely stops eating.
- Changing food abruptly, then treating the diarrhoea as an allergy.
- Leaving a window open without a screen.
Go to the clinic the same day for open-mouth breathing, a seizure, gums that look white, or a cat that strains for 6-8 hours without passing urine. Within 48 hours for not eating a full day, vomiting more than twice in 24 hours, or a 200 g drop in a month. Book within a week for a red gum line that bleeds when brushed, bad breath, or eyes that look cloudy in low light.
Your first 30 days
- Weigh twice and set a target range of 3.4-4.4 kg.
- Start brushing teeth three times a week and check the gum line weekly.
- Ask for the parents' PRA and PK DNA results, and get the cat tested if unknown.
- Book the 12-month eye exam and PCV if the cat is near that age.
Frequently asked
How often should an Abyssinian's teeth be brushed?
Three or four times a week for 30 seconds a side, with the gum line checked weekly, because periodontal disease is close to universal in this breed by middle age. A thin red border along the teeth is gingivitis and progresses faster here than in most shorthairs, so professional scaling starts at age 2 and repeats every 12 months if tartar returns quickly.
When does kidney testing start for an Abyssinian?
A urine protein:creatinine ratio at 2 years, then once a year, moving to twice a year from age 7, because familial amyloidosis leaks protein long before creatinine rises. Under 0.2 is normal, 0.2 to 0.4 means repeating in four weeks, and anything above 0.4 warrants a visit with blood pressure and imaging.
Is 3 kg too thin for an adult Abyssinian?
Females commonly sit at 3.0 to 4.0 kg and males at 3.5 to 4.5 kg, so 3 kg can be normal for a small female. Judge by body condition rather than the number alone: a score of 4 to 5 out of 9, a visible waist from above and ribs under a thin layer are the signs, while a 10% loss over three months needs a vet visit.
