British Shorthairs (9-18 lbs) are sturdy, calm cats — descendants of the iconic chunky teddy-bear-looking cats. Their build, temperament, and breed-specific health concerns shape what they should eat.
British Shorthair Health Considerations
- Hypertrophic Cardiomyopathy: Genetic heart disease common in breed.
- Obesity: Major concern. Their laid-back nature and large appetite make weight gain easy.
- Polycystic Kidney Disease: Some lines affected.
- Hemophilia B: Bleeding disorder in some lines.
- Dental disease: Common.
The Weight Challenge
British Shorthairs aren't naturally chunky — they're naturally sturdy. There's a difference. Overweight British Shorthairs face the same risks as any overweight cat: diabetes, joint problems, reduced lifespan.
Healthy targets:
- Females: 9-13 lbs
- Males: 12-18 lbs
- Should feel solid but with discernible waist
- Ribs palpable but not visible
What to Look For
Quality protein: Named meat first, 35-45% protein. Moderate fat: 12-16%. Avoid high-fat formulas given obesity tendency. Adequate taurine for cardiac health. Wet food emphasis: Helps satiety, urinary health. Indoor cat formulas appropriate for most British Shorthairs.
Cardiac Considerations
Given HCM susceptibility:
- Adequate taurine in food
- Avoid grain-free (some concerns)
- Annual cardiac auscultation starting at 2-3 years
- Genetic testing where possible
Portion Sizes
- 10 lb female: 220-280 cal/day
- 13 lb female: 270-340 cal/day
- 14 lb male: 280-360 cal/day
- 18 lb male: 340-440 cal/day
Strict scheduled feeding, no free-feeding.
What to Avoid
- Free-feeding (huge factor in obesity)
- High-calorie performance formulas
- Excessive treats
- Foods lacking taurine
FAQ
Aren't British Shorthairs supposed to be chunky?
Sturdy, not chunky. Overweight British Shorthairs are just overweight cats — same health risks apply.
The Bottom Line
British Shorthairs need quality protein, moderate fat, disciplined portion control, and wet food emphasis. Cardiac monitoring matters given breed predisposition.
