A Havana Brown fails on 3 clocks, and the mouth is the one that gets skipped: a full oral exam at every annual visit, full-mouth dental radiographs under anesthesia every 12 to 24 months from age 2, an echo from 12 months, and a monthly weigh-in. The mouth matters more than owners expect: the 2 dental problems in this breed hide under the gumline, where no toothbrush reaches. Weight belongs on the same page: an extra 500 g on a 4 kg cat is 12.5 percent, and that is where the echo gets harder to read.
3 dental problems, 3 different bills
Gingivitis is reversible: red gum margin, no attachment loss, 1 to 2 weeks of home care after a cleaning. Periodontitis is not reversible: attachment loss measured in millimeters, staged 1 to 4, and stage 3 or 4 means teeth that will be lost. Tooth resorption is different again, and it is the one that stings, because the enamel dissolves from the root upward, the crown snaps off, and the cat keeps eating. A cat that chatters at the food bowl, drops kibble after 2 chews, or eats on 1 side is describing resorption.
The X-ray is what decides the plan
Two thirds of each tooth sits under the gum, so a visual exam sees one third of the problem. Full-mouth radiographs, 6 to 10 films under anesthesia, 150 to 350 dollars on top of the cleaning, show root resorption, retained roots, and bone loss between the premolars where tartar never shows. A cleaning without films is a guess: in a cat over 5, the films often turn 1 extraction into 5. Cleaning plus films plus 1 to 2 extractions lands at 500 to 1,200 dollars; a full-mouth extraction with 4 weeks of soft food runs 1,200 to 2,500.
Anesthesia math, because that is the real gate
Pre-operative bloodwork at 80 to 150 dollars, an ECG over age 8, and an intravenous catheter at 40 to 90 are the 3 items that turn a dental into a safe dental. A grade 3 murmur on the pre-op exam cancels the dental and books an echo instead, which is why the 2 clocks run on 1 calendar. Most dentals take 20 to 40 minutes under gas, and the cat is usually home the same evening, eating soft food within 12 hours. Never fast a cat longer than 12 hours before anesthesia; 24 is a risk.
Weight: 1 kilogram is 25 percent
A 4 kg Havana Brown that reaches 5 kg is 25 percent over its own body weight, and body condition score 5 out of 9 is the target, not 6. Loss should run 0.5 to 1 percent of body weight per week, so 1 kg takes 4 to 6 months, not 6 weeks. Feed to a target weight, not to the current weight: roughly 45 to 55 kilocalories per kilogram of target weight per day, split into 2 meals plus 1 measured portion for the evening. Weigh the food on a kitchen scale in grams; a 10 percent scoop error is 30 g of dry food a day, which is 5 kg of food a year.
The 48-hour rule that follows obesity
An overweight cat that stops eating is a liver case in the making. Fat mobilized faster than the liver can process it causes hepatic lipidosis, and the usual trigger is 48 to 72 hours of anorexia, sometimes from something as small as a new food or a dental pain. The rule: no food for 24 hours is a phone call, 48 hours is an appointment with bloodwork, and any cat that vomits twice in 24 hours while refusing food goes in the same day. Obese cats that need a feeding tube run 800 to 2,000 dollars; the 24-hour phone call costs 0.
Heart and kidney share the annual visit
Hypertrophic cardiomyopathy (HCM) is reported in this breed at no published rate, so evidence is limited and the echo starts at 12 months: wall under 5 mm normal, 5 to 5.9 mm a recheck in 6 months, 6 mm or more meets the usual definition, left atrium to aorta ratio above 1.7 changes the plan that week. Every 12 months after, with blood pressure added from age 6, because hypertension and kidney disease arrive together and both make a dental risky. Urinalysis every 12 months at 40 to 90 dollars; specific gravity 1.035 to 1.060 and protein to creatinine under 0.2 are the 2 numbers to read first. Echo 220 to 450 dollars. A chest film at 120 to 300 dollars belongs on the list before any dental in a cat with a murmur, and 1 DNA swab at 80 to 200 dollars is the only genetic item here, bought once for breeding lines.
4 signals for the fridge door
- Chattering, head shaking at the bowl, or kibble dropped after 2 chews.
- Bad breath that returns within 8 weeks of a cleaning, or a brown line at the gum margin.
- Weight up 500 g in 8 weeks, or the waist disappearing when seen from above.
- Sleeping respiratory rate above 30 per minute, counted over 30 seconds and doubled.
Hour-level thresholds
| Signal | Window (hours) | Action | Cost (USD) | Cost (CNY) |
|---|---|---|---|---|
| Swelling under one eye | 24 | Same-day dental exam | 150 to 400 | 1,080 to 2,880 |
| Sudden collapse, white gums | 0 | Emergency, shock risk | 300 to 900 | 2,160 to 6,480 |
| Drooling, pawing the mouth, off food | 12 | Same-day oral exam | 90 to 250 | 650 to 1,800 |
| Obese cat, no food for 48 hours | 12 | Book today with bloodwork | 150 to 300 | 1,080 to 2,160 |
| Vomits twice in 24 hours, refuses food | 6 | Same-day exam, liver panel | 150 to 350 | 1,080 to 2,520 |
| Jaw chattering, dropping kibble for 2 weeks | 72 | Book dental with films | 500 to 1200 | 3,600 to 8,640 |
Row 1 is the one that gets delayed: a swelling under the eye looks like a cosmetic problem at 9 pm, and by morning it is a draining sinus from a dead upper fourth premolar.
The year in dollars
Quiet year: exam with bloodwork 180 to 350, urinalysis 40 to 90, echo 220 to 450, dental with films every 12 to 24 months at 500 to 1,200. Spreading the dental over 2 years gives 700 to 1,300 a year. A year with 1 extraction and 2 weeks of a soft diet adds 150 to 400. A policy written for a breed with a documented cardiac item runs 30 to 50 dollars a month, and dental illness cover is usually a paid add-on, often capped at 1,000 dollars a year: read that cap before assuming the mouth is covered.
5 steps this month
- Open the mouth at home once a week: lift the lip, look at the gum line, smell the breath.
- Book the dental consult with films, and ask for the pre-op bloodwork on the same visit.
- Switch to weighed meals in grams, and write the number on the food bin.
- Weigh monthly on the same scale, and record it next to the Tonkinese weight baseline.
- Book the 12-month echo with blood pressure, and compare the cardiac protocol in the Turkish Van screen.
Brushing daily beats every chew toy on the market, and 1 soft brush plus enzymatic paste, by veterinary prescription where a vet recommends it, is the whole kit. If the breed decision is still open, the breed quiz is the shorter path than a breeder list.

Frequently asked
How often does a Havana Brown need dental work under anesthesia?
Full-mouth radiographs with a cleaning every 12 to 24 months from age 2, plus a full oral exam at each annual visit. The films are the point: roughly two thirds of each tooth sits under the gum, so a visual exam misses root resorption and bone loss between the premolars. Cleaning with films costs 500 to 1,200 dollars, and pre-operative bloodwork at 80 to 150 dollars is part of the same visit.
Why is 48 hours without food an emergency in an overweight cat?
Fat mobilized faster than the liver can process it causes hepatic lipidosis, and 48 to 72 hours of anorexia is the usual trigger. A cat that refuses food for 24 hours earns a phone call, 48 hours earns an appointment with bloodwork, and vomiting twice in 24 hours while refusing food means going in the same day. A feeding tube runs 800 to 2,000 dollars, and the phone call costs nothing.
What is a safe weight loss rate for this breed?
About 0.5 to 1 percent of body weight per week, so 1 kg takes 4 to 6 months rather than 6 weeks. Feed roughly 45 to 55 kilocalories per kilogram of target weight per day, split into 2 meals, and weigh the food in grams on a kitchen scale, because a 10 percent scoop error is 30 g of dry food a day. Body condition score 5 out of 9 is the target.
