Every British Shorthair owner should understand the most common British Shorthair health problems before bringing a kitten home. Early detection can make a major difference to your cat’s quality of life. British Shorthairs have a reputation as one of the sturdiest and most easygoing pedigree breeds. Like every purebred cat, however, they can carry certain health risks linked to their genetics.
At Shorthair Cattery, we’ve bred British Shorthairs for 10 years. We screen every breeding cat for the conditions discussed below before pairing them. This guide covers eight common health problems, their causes, early warning signs, and typical management costs.
Key Takeaways
- HCM and dental disease rank as the two most commonly reported British Short-haired health problems
- PKD is preventable through DNA testing before breeding, not through treatment after diagnosis
- Most British Shorthairs live 12–20 years when owners manage these risks proactively
Why Do British Shorthairs Develop Health Problems?
Most British Shorthair health problems trace back to the same root cause: a limited gene pool. Breeding for the round face, cobby body, and dense coat also concentrated certain genetic mutations within pedigree lines. Popular sire lines used across multiple catteries can also spread hereditary conditions before anyone identifies them.
This does not mean every British Shorthair kitten will develop a hereditary condition. Responsible breeders test proactively instead of waiting for symptoms to appear. Informed owners also know what signs to monitor as their cats grow. Veterinary organizations such as the Cornell Feline Health Center and the American Veterinary Medical Association classify British Shorthairs as a generally robust breed overall, so context matters here as much as caution does. In the UK, the GCCF also publishes health testing guidance for registered breeders, worth reviewing if you’re buying from a UK-based cattery.
The 8 Most Common British Shorthair Health Problems
Below, we break down each condition, starting with the most serious and working toward the more manageable ones.
1. Heart Disease: Hypertrophic Cardiomyopathy (HCM) and Dilated Cardiomyopathy (DCM)
HCM ranks as the most common heart disease in cats, and British Shorthairs rank among the breeds it affects most frequently. The condition thickens the walls of the heart over time, which can eventually reduce heart function, cause blood clots, or trigger heart failure.
Veterinarians strongly suspect that British Shorthair HCM runs in family lines, so breeder screening offers the best defense. Most reputable breeders test their breeding cats’ hearts using an echocardiogram, typically starting around 1–2 years of age and repeating the scan periodically throughout the cat’s breeding life.
A second, less common heart condition, dilated cardiomyopathy (DCM), can also affect these breeds. Unlike HCM, DCM stems from a taurine deficiency rather than genetics alone, which is why a high-quality, taurine-complete diet matters just as much for long-term heart health as genetic screening does.
Warning signs of HCM:
- Lethargy or reduced activity
- Rapid or labored breathing
- Reduced appetite
- Sudden weakness in the back legs
Importantly, HCM can stay silent for years, which explains why periodic cardiac checks matter even when a cat seems perfectly healthy. In terms of cost, diagnostic echocardiograms typically run $300–$600, while ongoing medication and monitoring for a diagnosed cat can cost $30–$100 per month depending on your location and vet.
Always make sure to ask your breeder, “Have you screened the parents for HCM by echocardiogram, and can you show me the documentation if necessary?”
2. Polycystic Kidney Disease (PKD)
British Shorthair kidney disease, more formally known as PKD, causes small fluid-filled cysts to form in the kidneys. Kittens carry this condition from birth, but the cysts grow slowly, so symptoms—increased thirst, more frequent urination, and weight loss—typically don’t surface until the cat reaches 7 years or older.
A single identifiable gene causes PKD, which means a simple DNA test can confirm whether a breeding cat carries it. Consequently, any breeder producing British Shorthairs should readily show you documented PKD-negative results for both parents. On average, a PKD DNA test costs $40–$60 and only needs to happen once in a cat’s lifetime, making it one of the most cost-effective screenings available.
Ask your breeder, “Did you DNA test the parents for PKD, and did both come back negative?”
3. Brachycephaly-Related Issues
British Shorthairs carry a naturally flat, round face, and in some lines that facial structure leans toward brachycephaly—a shortened skull shape that can crowd the airway and tear ducts. Mild brachycephaly rarely causes problems, but cats bred for a more extreme “flat” look (a very short muzzle, nostrils sitting level with the eyes) can develop breathing difficulty, snoring, exercise intolerance, and chronic tear staining.
Warning signs to watch for: noisy or labored breathing, exercise intolerance, frequent tear staining, or difficulty eating comfortably.
Ask your breeder, “How extreme is the facial profile in this bloodline, and have any relatives needed treatment related to brachycephaly?” Avoiding kittens from parents with an extreme flat-faced look, and choosing a breeder who favors a moderate profile in line with the breed standard, is the best prevention available.
4. Dental Disease
British Shorthairs carry broad heads and densely packed teeth, a combination that makes them more prone than many breeds to plaque buildup, tartar, and gum disease. If left untreated, dental disease can progress to painful tooth loss and even affect the heart and kidneys through chronic low-grade infection.
Brushing your cat’s teeth remains the single most effective prevention, especially when you start in kittenhood so it becomes a normal part of the routine. Dental treats and water additives support brushing, but they don’t replace it. Meanwhile, annual dental checks catch problems while they’re still easy to treat, and a professional cleaning under anesthesia (needed roughly every 1–3 years for most cats) typically costs $200–$600.
5. Feline Lower Urinary Tract Disease (FLUTD)
FLUTD covers several conditions that affect the bladder and urinary tract rather than describing one single disease. It shows up across most breeds, including British Shorthairs, and owners often mistake it for “bad litter box behavior.”
Warning signs of FLUTD:
- Straining to urinate
- Blood in the urine
- Frequent litter box trips with little output
- Crying while urinating
- Urinating outside the litter box
If you notice any of these signs—especially in male cats, where a blocked urethra becomes a medical emergency—take your cat to the vet the same day. Feeding a urinary-health diet and encouraging water intake (wet food helps, since this breed famously drinks less than it should) goes a long way toward prevention.
6. Obesity, Joint Strain, and Diabetes Risk
British Shorthairs carry a naturally sturdy, cobby build, a slower metabolism, and a laid-back energy level, and this combination makes gradual weight gain common. Excess weight, in turn, raises the risk of joint strain and arthritis as the cat ages, particularly given its already heavier bone structure.
Weight gain often creeps up unnoticed, so weighing your cat periodically, measuring food instead of free-feeding, and scheduling regular play sessions can prevent most weight-related problems before they start. For context, an ideal adult British Shorthair typically weighs 9–18 pounds depending on sex and frame, and your vet can tell you where your cat should sit within that range.
Carrying excess weight for a long stretch of time also raises the risk of type 2 diabetes, so keeping a British Shorthair lean throughout adulthood protects more than just their joints. Rather than relying on the bathroom scale alone, ask your vet to assess your cat’s body condition score at each visit—a healthy score shows a visible waist from above and ribs you can feel but not see.
7. Eye Conditions
British Shorthairs can develop cataracts, which cloud the lens of the eye and rank among the more common causes of vision loss in aging cats. Even so, most cats adapt well and continue living full, comfortable lives despite reduced sight, especially in a familiar home environment. Routine vet checks typically catch early lens changes before they meaningfully affect day-to-day life.
British Shorthairs can also develop entropion, a condition where the eyelid rolls inward and irritates the eye’s surface. Mild cases often need no treatment beyond monitoring, but a vet may recommend minor corrective surgery when irritation becomes chronic. Watch for excessive tearing, squinting, or redness around the eye.
8. Line-Specific and Minor Concerns
Beyond the conditions above, individual bloodlines carry their own patterns—mild respiratory traits, specific joint sensitivities, or other minor recurring issues. In fact, this is one of the most overlooked parts of buying a kitten: a good breeder doesn’t just know the breed’s general risks; they know their own line’s history and share it honestly rather than reciting generic breed facts.
Feline infectious peritonitis (FIP), while not unique to the breed, is also worth knowing about: it’s a serious viral disease that can affect any cat, and kittens raised in crowded or high-stress breeding environments carry a somewhat higher risk of exposure. Choosing a breeder who keeps a clean, low-stress cattery reduces this risk considerably.
How These Health Problems Are Diagnosed
Understanding how vets detect these conditions helps you know what to expect at checkups. HCM screening relies on an echocardiogram. This ultrasound examines the heart and usually takes 20–30 minutes. A vet or veterinary cardiologist can perform the procedure. Most cats do not need sedation.
PKD screening can involve a simple cheek swab or blood sample. The sample goes to a genetics laboratory for analysis. Results are typically available within 1–2 weeks. Vets can also identify dental disease, cataracts, entropion, and brachycephaly-related traits during a physical exam.
FLUTD evaluation usually begins with a urinalysis. These screening methods are generally straightforward and non-invasive. They also do not usually require an overnight stay. This can make routine screening easier when cost or convenience feels like a concern.
Kitten Wellness Checks and Growth Monitoring
New owners often ask what tests British Shorthair kittens need during their first weeks at home. A full wellness exam should take place within the first week. Your vet can check the heart, lungs, eyes, ears, joints, gums, and abdomen. The exam can also reveal early signs of potential health problems.
Owners also frequently ask, “Are British Shorthairs slow to grow?” The answer is yes, by design. This breed matures slowly and may not reach full adult size until 3–5 years old. Weekly weight checks during the first several months can help confirm steady growth. They can also show whether your kitten is gaining weight too quickly or too slowly.
How to Prevent and Monitor British Shorthair Health Problems at Home
Because this breed tends to mask discomfort well, a few simple weekly habits make an outsized difference in catching British Shorthair health issues early:
| Habit | What to Watch For |
|---|---|
| Weight checks | Slow, steady weight changes over a few weeks |
| Litter box output | Straining, frequency changes, or blood |
| Appetite | Any noticeable drop or increase |
| Coat and skin | Lumps, dry patches, or tenderness during brushing |
| Energy level | A sudden dip in a normally food-motivated, mellow cat |
| Breathing | Open-mouth breathing or noticeably heavier breathing after activity |
Additionally, scheduling a wellness exam every 6–12 months, rather than only visiting the vet when something seems wrong, gives your vet a baseline to compare against as your cat ages.
Questions to Ask Before You Buy a Kitten
A responsible breeder welcomes these questions rather than deflecting them:
- Have you screened the parents for HCM by echocardiogram?
- Did you DNA test the parents for PKD, with documented negative results?
- What health history does this specific bloodline carry?
- What vaccinations and vet checks has the kitten already received?
- Do you offer a health guarantee, and what does it cover?
So, Are British Shorthairs Healthy Overall?
Not really a cause for worry. Every purebred cat carries some hereditary risk. When people ask whether British Shorthairs are healthy, the honest answer is yes, on the whole. This is a resilient, long-lived breed. Many British Shorthairs can live comfortably into their late teens with good care.
Rather than avoiding the breed, use this list as a guide. Learn what to watch for and which questions to ask before and after adoption. Understanding potential health concerns can help you make informed decisions about your cat’s care.
Choose a breeder who screens for HCM and PKD. Stay consistent with dental care and weight management. Pay attention to small daily changes in your cat’s behavior. These steps can help your British Shorthair thrive for years to come.

Frequently Asked Questions
What are the most common British Shorthair health problems? Hypertrophic cardiomyopathy (HCM) and dental disease top the list of the most common British Shorthair health problems, followed by obesity-related joint strain, PKD, and FLUTD.
Do British Shorthairs have breathing problems? Most British Shorthairs breathe normally, but cats bred with an especially flat facial profile can experience brachycephaly-related breathing difficulty. Choosing a kitten from a breeder who avoids extreme flat-faced breeding reduces this risk.
Does obesity increase diabetes risk in British Shorthairs? Yes. British Shorthairs carry a naturally stocky build and lower activity level that makes weight gain common, and sustained excess weight significantly raises the risk of type 2 diabetes.
Are British Shorthairs a generally healthy breed? Yes. British Shorthairs carry a reputation as a robust, long-lived breed, with an average lifespan of 12–20 years. Still, like all pedigree cats, they carry a handful of breed-specific risks worth screening for.
Can HCM be cured? No cure exists for HCM, but medication often manages it well once diagnosed, and early detection through regular cardiac screening significantly improves long-term outcomes.
How can I tell if my British Shorthair kitten’s parents were health tested? Ask the breeder directly for echocardiogram results (for HCM) and PKD DNA test results for both parents. A reputable breeder keeps this documentation readily available.
Do British Shorthairs have kidney problems? Some British Shorthairs carry the gene for polycystic kidney disease, which causes fluid-filled cysts in the kidneys. A DNA test confirms whether a cat carries the gene, so breeding cats should undergo testing before pairing.
How much does it cost to manage British Shorthair health problems? Costs vary by condition: a PKD DNA test runs $40–$60 as a one-time cost, while ongoing HCM management can run $30–$100 per month. Routine dental cleanings typically cost $200–$600 every 1–3 years.
