A Nebelung needs 4 things tracked, and only 1 of them is a lab test: an echocardiogram for hypertrophic cardiomyopathy (HCM), a dental score, a monthly weight, and a urinalysis. The breed's small founding population makes a broad DNA panel worth doing once, but it does not replace the 3 checks that depend on the cat's body rather than its genotype. Everything below is scheduled by month, not by symptom.
Why the order runs heart, mouth, then scale
HCM is silent until the atrium dilates, so the echo comes first and repeats on a fixed interval. Dental disease is painful but rarely stops a cat eating, which is why it needs a score rather than a complaint. Weight sits third because it feeds both: a 1 kg gain raises the work of a heart that may already be thick, and it shortens the time a cat tolerates anesthesia for a dental cleaning. Run the 3 in that order and 1 visit can cover them in 40 minutes.
Heart: first echo at 12 months, then 2 numbers
Screen at 12 months, repeat every 12 months to age 6, then every 6 months to age 10. The report needs 2 measurements to be useful: diastolic wall thickness (IVSd) and the left atrium to aorta ratio (LA/Ao). Under 5.0 mm and a ratio under 1.5 means a normal screen. At 5.0 to 5.9 mm, or a ratio of 1.5 to 1.7, the recheck drops from 12 months to 3. From 6.0 mm, or a ratio above 1.7, most cardiologists treat and recheck in 3 to 6 months. A proBNP test at 40 to 80 USD helps when a cat will not tolerate a scan, but a normal value does not cancel the echo. The imaging protocol in the Maine Coon heart screen applies here too, since both breeds carry the same disease family.
A small gene pool: 3 things that actually help
The founding group behind this breed is narrow, and a narrow pool does not create a specific disease. It raises the chance that 2 carriers meet. That changes the plan in 3 ways. One: ask for a 3 generation pedigree and the inbreeding coefficient before you buy, and prefer a pairing with 2 distinct lines behind it. Two: run 1 broad panel of 40 to 60 variants at 4 months, near 150 to 250 USD, and keep the report for life. Three: tell the breeder the result, because a carrier has no signs and only the record prevents a repeat pairing. A panel covers known mutations only, so a clear result never means a clear cat.
Mouth: a 0 to 4 score every 6 months
Calculus and gingivitis are graded, not guessed. Grade 0 is clean. Grade 1 is soft film on the crown. Grade 2 is calculus along the gum line under 1 mm. Grade 3 is calculus over one third of the crown with red, bleeding gums. Grade 4 is a pocket deeper than 5 mm, mobile teeth, or pus. Grades 1 and 2 get a cleaning every 12 months, grade 3 every 6 months, and grade 4 now, with dental X-rays and a tooth-by-tooth plan. Home brushing 3 times a week is the minimum that helps, and daily is better; an enzymatic paste is enough. Cleaning runs 250 to 600 USD with anesthesia and films, and an extraction adds 30 to 80 USD per tooth.
Scale: 1 weigh-in a month, 2 numbers to hold
Score body condition on the 9 point scale at every visit; 5 is the target and 7 or above is the point where a plan starts. Weigh monthly on the same scale, and treat a 5 percent change in 30 days as a finding. A 4.5 kg cat needs roughly 215 kcal a day at maintenance, and a weight loss plan uses 80 percent of the calories for the target weight, not the current one. Two play sessions of 10 minutes a day do more for an indoor cat than free feeding with a diet food. Plot the monthly figure on a weight trend chart so a slow drift of 200 g over 3 months is visible before it becomes 1 kg.
Four signals, no equipment needed
One: sleeping respiratory rate, counted for 30 seconds and doubled, 3 times a week; 30 or below is normal and 40 or above needs a call. Two: chewing on one side, dropping food, or a 2 second pause before swallowing, which points at a painful tooth. Three: breath that smells of decay rather than food, checked by smelling at the muzzle 1 time a week. Four: weight and waist, where ribs you can no longer feel under light pressure means a score of 7 or more. Add a seasonal check of the house against the toxic plant list, since lilies and several common houseplants cause kidney injury within 24 to 72 hours of a single chewed leaf.
Two clocks: hours for symptoms, months for teeth
Five signals, 5 different clocks. Breathing is the fastest and dental pain the slowest, which is why a fixed table beats instinct.
| Signal | Watch window | Vet within | Usual cause |
|---|---|---|---|
| Breathing fast at rest, 40 or more | 10 min | 2 hours | HCM, fluid |
| Open mouth breathing at rest | none | 0 hours | Emergency |
| Drooling, face swelling on 1 side | 2 hours | 6 hours | Abscess |
| No food for 48 hours | 24 hours | 12 hours | Dental, GI, kidney |
| Hiding, no urine for 24 hours | 12 hours | 6 hours | Block, pain |
| Weight down 5 percent in 30 days | 30 days | 7 days | Dental, thyroid, GI |
The dental table is the second clock, because a grade decides the month rather than the hour.
| Grade | Finding | Cleaning interval |
|---|---|---|
| 0 to 1 | Clean or soft film | 12 months |
| 2 | Calculus under 1 mm | 12 months |
| 3 | Calculus over one third, bleeding gums | 6 months |
| 4 | Pocket over 5 mm, mobile tooth | 0 to 4 weeks |
Any pain relief or antibiotic after a cleaning is given as a class, an NSAID or an antibiotic, and only on a veterinary prescription written after an exam.
What a year costs, and the calendar
Exam 40 to 70 USD, echo 120 to 250, DNA panel 150 to 250, urinalysis 40 to 80, dental cleaning 250 to 600. Year 1 totals 500 to 900 USD with a cleaning, and 250 to 450 in the years without one. The calendar: month 4 panel, month 12 echo plus urine plus dental score, month 18 dental score, month 24 echo plus dental, then 6 month dental checks and 12 month echoes, with a weigh-in every month in between.
Five steps for the next 12 months
- Book the 12 month echo and ask for IVSd and LA/Ao in the written report.
- Start brushing 3 times a week, 30 seconds a side, with an enzymatic paste.
- Weigh on the 1st of each month and write the number in the same place.
- Ask for a 3 generation pedigree and the inbreeding figure before any purchase.
- Set a phone reminder for the 6 month dental score, since pain shows late.

Frequently asked
How often does a Nebelung need an echocardiogram?
Every 12 months from age 1 to age 6, then every 6 months to age 10. The report should list wall thickness and the left atrium to aorta ratio, because a single line saying normal gives you nothing to compare next year. If either number crosses into the 5.0 to 5.9 mm or 1.5 to 1.7 band, the interval drops to 3 months.
Does a small gene pool mean the cat will be sick?
No. A narrow founding group does not create a disease, it raises the odds that 2 carriers of the same recessive mutation are paired. That is why the practical steps are a 3 generation pedigree, a broad DNA panel once at 4 months, and telling the breeder the result. A clear panel covers known mutations only, so the yearly echo and dental score still matter.
When should dental cleaning start?
At the first grade 2 score, which often appears between 2 and 4 years old, and then every 12 months while the score stays at 1 or 2. Grade 3 moves the interval to 6 months, and grade 4 means a cleaning within 4 weeks with dental X-rays. Brushing 3 times a week at home slows the climb between cleanings.
