The British Shorthair is the UK’s most popular pedigree cat — and for good reason. Their dense, plush “teddy bear” coat, round copper or golden eyes, and calm, dignified temperament make them one of the most visually appealing and temperamentally easy-going cats available. The classic “British Blue” is the most recognised variety, but British Shorthairs come in a remarkable range of colours and patterns. They are robust, independent without being aloof, and form steady, affectionate bonds with their families. They also carry two important genetic health conditions from their breeding history that every prospective owner should understand.

Health — Key Conditions
HCM — Hypertrophic Cardiomyopathy
HCM is the most common heart disease in all cats, and British Shorthairs have a known genetic predisposition:
- The heart muscle walls thicken, reducing the heart’s ability to fill and pump blood efficiently
- Can be clinically silent for years — cats may show no symptoms until advanced disease (laboured breathing, lethargy, collapse)
- No DNA test is currently available for HCM in British Shorthairs (unlike Maine Coons, where the gene has been identified)
- Screening: echocardiogram by a veterinary cardiologist — reputable breeders screen breeding cats regularly. Ask for echocardiogram certificates
- Treatment: medication (atenolol, clopidogrel) can manage symptoms and slow progression but cannot cure the condition
PKD — Polycystic Kidney Disease
British Shorthairs carry PKD risk due to historical crossbreeding with Persian cats:
- Fluid-filled cysts develop in the kidneys, growing gradually and eventually leading to kidney failure
- Clinical signs typically appear between 3 and 10 years: increased drinking/urination, weight loss, lethargy, poor appetite
- DNA test available — reputable breeders test all breeding cats for PKD. Ask for certificates showing PKD-negative status
- Management: no cure, but early detection via ultrasound allows supportive treatment (renal diet, fluid therapy) that can extend comfortable life significantly
Obesity
British Shorthairs are naturally low-energy cats who love food — a combination that makes them one of the most obesity-prone breeds. Strict portion control, measured feeding (never free-feeding), and interactive play are essential. An overweight British Shorthair faces joint problems, diabetes, and reduced lifespan. A lean British Shorthair is a healthy British Shorthair.
FAQs
Are British Shorthairs really not lap cats?
Generally no — and this is a genuinely important consideration. Most British Shorthairs prefer to sit next to you rather than on you. They are affectionate, follow you between rooms, and enjoy being near their people — but they are typically not clingy or cuddly in the way Ragdolls or Burmese are. If you want a cat that actively seeks lap time and cuddles, a British Shorthair may disappoint. If you want a calm, dignified companion who shows love through quiet presence, they are exceptional.
