The British Shorthair is one of the most popular pedigree cats — placid, undemanding, and famously round-faced. They're robust overall, but their breed genetics carry a couple of significant conditions, and their laid-back nature makes weight gain a real factor in long-term health. Here's the picture for Canadian owners.
Common British Shorthair health issues
| Condition | How common | Typical treatment cost (CAD) |
|---|---|---|
| Hypertrophic Cardiomyopathy (HCM) | The defining breed cardiac concern | High — lifelong cardiac management; can be sudden |
| Polycystic Kidney Disease (PKD) | Breed-associated, genetic | High over time — lifelong kidney management |
| Obesity | Very common — calm, food-motivated breed | Moderate ongoing, compounds other conditions |
| Dental disease | Common in cats generally | Moderate per cleaning, recurring |
| Hemophilia B (specific lines) | Breed-associated, genetic; uncommon | Variable; relevant for surgery |
| Diabetes (linked to obesity) | Elevated with weight gain | Lifelong insulin and monitoring |

Our Recommendation
For a British Shorthair, comprehensive coverage enrolled early is the right call. HCM and PKD are both genetic, both serious, and both become pre-existing exclusions once diagnosed — so insure while your cat is young. Because obesity is such a strong tendency in this breed and drives diabetes and joint strain, weight management is the single most impactful thing you can do alongside coverage.
Frequently asked questions
Are British Shorthairs expensive to insure?
Premiums are moderate — a little above the average domestic cat because of the HCM and PKD risk, but reasonable. Given that cardiac and kidney conditions are exactly what drives large feline bills, the coverage is well justified.
Why is obesity such a concern in this breed?
British Shorthairs are calm, sedentary, and food-motivated, which makes weight gain easy. Obesity compounds into diabetes, joint problems, and a shorter life — portion control and play are essential. It's the most preventable factor in the breed's long-term health costs.
Should I screen for HCM and PKD?
It's worth discussing with your vet. Both conditions have genetic and screening components, and responsible breeders test breeding cats. For owners, the key point is that both become pre-existing exclusions once diagnosed, so insuring before any cardiac or kidney issue appears is what protects you.
How long do British Shorthairs live?
Typically 12–16 years, sometimes longer. Their longevity means more years for chronic conditions like kidney disease, dental issues, and obesity-related diabetes to appear — which is why an early, continuous policy delivers the most value.
