Complete Guide to Rexdoll Regular Check-up Schedules: Age-Specific Common Diseases and Timing

ImmunityBreed HealthMeongsiljang Veterinary Advisory Board

Rexdolls are prone to genetic conditions, including hypertrophic cardiomyopathy (HCM), making age-specific regular check-ups essential. This article outlines the recommended schedule and must-have tests for each life stage.

What Are Rexdoll Regular Check-ups?

Regular check-ups for Rex Dolls are age-specific health screening programs designed to detect breed-specific risks such as hypertrophic cardiomyopathy (HCM), kidney disease, and urinary tract issues at an early stage. Annual to biannual check-ups are essential. In particular, Rex Dolls require separate cardiac ultrasound and genetic testing in addition to routine health exams. Consistent monitoring from the asymptomatic phase is crucial to prevent sudden onset of disease.

Why Are Check-ups More Important for Rexdolls?

Rexdolls are genetically predisposed to hypertrophic cardiomyopathy (HCM) due to breed-specific traits. According to veterinary cardiology textbooks, the thickening of the left ventricular wall in feline HCM varies significantly among individuals, and diagnosis heavily depends on the examiner’s experience, making it difficult to assess based solely on auscultation or outward symptoms. Therefore, cardiac ultrasound is considered the most sensitive non-invasive test for detecting HCM, while genetic testing is used as an additional tool to support diagnosis. Since HCM often progresses without obvious symptoms, delayed detection can occur if regular check-ups are not conducted to monitor the condition from its asymptomatic stage.

Age-Specific Check-up Intervals at a Glance

The types and frequency of tests needed vary depending on whether your cat is a kitten, adult, or senior. Please use the table below as a calendar for pet owners. In particular, it's important to schedule the first cardiac ultrasound around the age of one, as it will serve as a baseline for future comparisons.

Rexdoll Age-Specific Check-up Schedule

Item	Kitten stage (~1 year)	Adult stage (1–7 years)	Senior stage (7+ years)
Basic health checkup	Once a quarter	Once a year	Twice a year
Echocardiography	Once every 6–12 months	Once a year	1–2 times a year
MYBPC3 genetic test	Once (right after adoption)	Keep results on file	Keep results on file
Blood/urine test	Once a year	Once a year	Twice a year
Dental checkup	From 6 months	Once a year	1–2 times a year

These are recommended intervals considering the Ragdoll's risk of heart disease. A veterinarian may adjust them according to each individual's condition.

Cardiac Ultrasound Is Essential, Not Optional

A negative genetic test result doesn’t mean you can completely relax. Hypertrophic cardiomyopathy can also be caused by other, as-yet-undiscovered genetic mutations, so Rexdolls should definitely have a baseline cardiac ultrasound around the age of one. Even if no heart murmur is audible, the thickness of the heart walls can only be accurately measured via ultrasound.

Items to Definitely Check During Check-ups

Our Rexdoll health checkup includes one additional level of testing compared to a standard exam. - Echocardiogram: Measures left ventricular wall thickness and left atrial size - MYBPC3 genetic test: Determines homozygous or heterozygous carrier status - Blood pressure measurement: Early detection of asymptomatic hypertension - Kidney function markers (SDMA and creatinine): Early indicators of kidney failure - Urinalysis: Checks for risks of bladder stones and urinary tract infections - Weight and body condition assessment: Obesity places additional strain on the heart

Monitor Urinary and Kidney Health as Well

As Rexdolls age, they become more susceptible to chronic kidney disease (CKD). Veterinary textbooks emphasize that early diagnosis and management are crucial for a better prognosis. The sooner we identify and address factors that accelerate progression—such as anemia, hyperphosphatemia, hypertension, and proteinuria—the more favorable the outcome tends to be. Cats with CKD often have concurrent systemic hypertension, so if one condition is diagnosed, the other should also be evaluated. During routine check-ups, combining blood and urine tests can help detect subtle changes before kidney values significantly worsen. Additionally, keeping track of your cat’s daily water intake and urination frequency can be very helpful.

Advance Your Regular Check-up If You See These Signs

There are warning signs that mean you shouldn’t wait for your scheduled checkup. If your pet’s breathing is faster than usual (more than 40 breaths per minute), if they suddenly lose strength in their hind legs, if their appetite or activity level drops for over a week, or if they’re going to the bathroom more or less than usual, you should visit the vet within 24 hours. These changes could be early warnings of hypertrophic cardiomyopathy, blood clots, or kidney failure.

What Owners Should Do at Home

Regular check-ups don’t end at the clinic. Once a month, measure and record your pet’s resting respiratory rate during sleep (normal is under 30 breaths per minute), and weigh them monthly using the same scale. Use grooming time—such as nail trimming and brushing—to gently feel their chest, abdomen, and joints for any lumps or signs of pain. These records will greatly assist your veterinarian during the next check-up.

Frequently Asked Questions

When is the best time for a Ragdoll to have its first cardiac ultrasound?

We recommend having this test done either right after adoption along with a basic health checkup, or between 6 months and 1 year of age. The left ventricular wall thickness measured at this time will serve as a lifelong reference point for comparison.

If the genetic test comes back negative, does that mean I don’t need to get an echocardiogram?

Not necessarily. Hypertrophic cardiomyopathy can also be caused by other, yet-unknown genetic mutations, so regular cardiac ultrasounds are essential even if the test result is negative.

My pet looks healthy—do they still need an annual checkup?

Yes, in Ragdolls, both hypertrophic cardiomyopathy and kidney disease often progress without symptoms. By the time signs appear, the condition is usually already advanced, so annual check-ups are the safest approach.

I’m worried about the cost of the checkup. If I had to prioritize, what should I focus on first?

An echocardiogram combined with blood and urine tests is the top priority. Dental and imaging exams can be adjusted to every other year in consultation with your veterinarian.

For senior Ragdolls, the stress of anesthesia makes ultrasounds a concern.

Echocardiograms are performed without anesthesia. Since it is a non-invasive test that only requires the cat to lie on its side for a short time, it is safe for senior cats.
