There is no breed-wide screening programme for the Chinese Li Hua and no registry data to copy. Hip dysplasia is reported in the breed but the reports are thin, and any percentage quoted for this breed is a number nobody measured. So the plan uses what is checkable in any cat: hips at 12 months, a waistline from 2 years, teeth every 6 months, and a baseline blood and urine panel that gets repeated on a date rather than on a symptom.
1. Hips: the radiograph at 12 months
Hip dysplasia is reported in cats far less than in dogs: cats hide a limp, and nobody films them. The screening test is a ventrodorsal pelvis radiograph under light sedation at 12 months, when the femoral heads and acetabula have finished ossifying and the position is repeatable. Ask for 2 numbers: the Norberg angle, where 105 degrees or more is the usual normal cut-off, and a distraction index if the clinic offers PennHIP-style views, where 0.3 or below is tight and 0.7 or above is loose.
A hands-on exam decides whether to film early: watch the cat walk away and back, feel for thigh muscle wasting, and ask for an Ortolani manoeuvre on both hips. Bunny-hopping up the stairs, or refusing a jump it took 6 months ago, earns the film before 12 months. A normal film needs no repeat; laxity means a second film at 24 months, plus weight control, a soft landing pad, and steps instead of a 90 cm counter.
2. The waistline: the best-evidenced item on the list
Adult obesity is the one problem here with solid general evidence behind it, and a kitchen scale is enough to track it. Score body condition 1 to 9 monthly, target 5, weigh on the same scale on the same date, and log it on a weight trend chart so a 300 g drift shows as a line. A 10% gain in 90 days means the ration is re-measured; a 5% loss in 30 days means a vet visit within 72 hours, because unexplained loss in an adult cat is disease until proven otherwise.
Feed to resting energy requirement, roughly 70 × weight in kg to the power 0.75, about 230 kcal a day for a 5 kg cat, and start a loss plan at 80% of the figure for the target weight. Weigh the dry food for 7 days before trusting a cup, since a level and a heaped scoop differ by 20% to 30%, which is 300 to 450 g of body weight in 3 months. Prescription weight-loss diets and any appetite or thyroid drug come from the veterinarian, who also sets the recheck.
3. Teeth: calculus on a 6-month clock
Calculus is the finding owners see first: a brown line at the gum line of the upper fourth premolar and the lower canines, hard to the touch and no longer brushable. Plaque re-forms within 24 to 48 hours of a missed brushing and mineralises over weeks, so brush daily with a pet enzymatic paste and treat 3 sessions a week as the floor. Probe weekly with a fingertip: a red rim along 2 or more teeth is gingivitis, and a gum line that has receded 1 mm and exposed root is periodontitis, which needs a chart and radiographs.
Book a check every 6 months, and a scale and polish under anaesthesia once calculus crosses the gum line. Before the anaesthetic, ask for a blood panel and a heart listen, because a murmur means an echo first. After scaling the clock restarts: without daily brushing, calculus is back at the gum line in 6 to 12 months.
4. Build the baseline you will compare against
With no breed reference values and no validated breed DNA test to order, your own 12-month numbers become the reference. At 12 months take a full blood count, a chemistry panel, a urinalysis with specific gravity, and an echocardiogram, the same starting point as the Maine Coon screen; repeat blood and urine every 12 months to age 6, then every 6 to 12 months, and add total T4 from 7 years. Three values matter most: urine specific gravity below 1.035 means concentrating ability is slipping, creatinine above the laboratory's upper limit starts the kidney staging conversation, and systolic blood pressure at 160 mmHg or more on 2 visits needs treatment. The echo uses the usual feline cut-offs: wall under 5.0 mm normal, 5.0 to 5.9 mm a 6-month recheck, 6.0 mm or more the definition, and LA/Ao above 1.7 a dilating atrium.
5. The calendar you write yourself
| Age | Hip film | Blood + urine per year | Echo per year | Dental check (months) | Weigh-ins per month |
|---|---|---|---|---|---|
| 6 months | 0 | 0 | 0 | 6 (first look) | 1 |
| 12 months | 1 (baseline) | 1 | 1 | 6 | 1 |
| 24 months | 1 only if laxity seen | 1 | 1 | 6 | 1 |
| 3 to 6 years | 0 | 1 | 1 | 6 | 1 |
| 7 years and up | 0 | 2 (with T4) | 1 | 4 | 2 |
6. Four signals you can see at home
- Stairs and landings. Bunny-hopping, a 3 to 5 second pause before a jump, or refusing a 60 cm surface it used last month is a hip question.
- Ribs and waist. A flat hand on the ribs every 2 weeks, then a look from above: no waist means the ration moved before the scale did.
- Breath at rest. Sleeping respiratory rate, 30 seconds twice a week, 30 per minute as the ceiling; 40 once or 30 three times is a call.
- The gum line. A brown line at the upper fourth premolar, breath that changed in 2 weeks, or food dropped while eating means a dental exam within 7 days.
7. Hours, not appointments
| What you see | Number | Act within |
|---|---|---|
| Open-mouth breathing at rest | any | 0 to 1 hour |
| Sleeping respiratory rate | 40+ once, 30+ x3 | 2 hours, else 24 hours |
| Sudden hind-limb paralysis, cold pads | 1 or 2 legs | 30 minutes |
| No urine in 24 hours | 24 hours | 2 hours |
| Not eating, overweight cat | 24 hours | 4 to 6 hours |
| Vomiting 3 or more times in 12 hours | 3 | 6 hours |
| Weight down 5% in 30 days | 5% | 72 hours |
| Bleeding gum on contact | 2+ teeth | 7 days |
8. What it costs
| Item | USD | CNY |
|---|---|---|
| Exam and history | 50 to 90 | 100 to 250 |
| Hip radiograph with sedation | 120 to 250 | 300 to 700 |
| Blood count, chemistry, urinalysis | 80 to 200 | 200 to 500 |
| Echocardiogram | 220 to 450 | 600 to 1,200 |
| Scale and polish with anaesthesia | 300 to 700 | 800 to 2,000 |
| Year one total | 420 to 850 | 1,000 to 2,400 |
9. Four steps for this month
- Weigh the cat and start a written log; the first number is the only free baseline.
- Book the 12 month visit as one block: hip film, blood, urine, echo.
- Start brushing tonight, with 3 sessions a week as the minimum.
- Write the sleeping respiratory rate on the same log, twice a week, 30 seconds each.
None of this replaces a diagnosis: hip dysplasia is read on a film, obesity on a scale and a body condition score, calculus on a probe, kidney and heart disease on blood, urine and ultrasound. The breed may have no data, but your cat can still have a baseline.

Frequently asked
Why is there no breed screening protocol for the Li Hua?
Because there is no registry-wide examination, no shared scoring body and very few health records. The reports that exist are case reports and clinic impressions, so no honest prevalence figure can be given, and screening follows general cat medicine instead.
What does a hip radiograph at 12 months actually show?
It shows the shape of the femoral head and acetabulum and gives a Norberg angle, with 105 degrees or more usually read as normal, plus a distraction index where the clinic offers it. It cannot predict lameness alone, so the exam and the gait matter too.
How much should the first year cost?
About 420 to 850 dollars, or 1,000 to 2,400 CNY, covering the exam, a sedated hip film, blood count with chemistry and urinalysis, an echo and a dental check. Scaling under anaesthesia is separate, at 300 to 700 dollars.
