British Shorthair vs Selkirk Rex — Breed Comparison

About the British Shorthair

The British Shorthair is one of the oldest and most recognizable cat breeds — tracing its roots to the domestic cats of Roman-era Britain, later refined through selective breeding in the 19th century. This large, stocky breed weighs 9–18 pounds and is famous for its round face, dense double coat, and broad, powerful build. While the "British Blue" (solid gray-blue) is the most iconic variety, the breed comes in an extensive range of colors and patterns.

Temperament & Personality

British Shorthairs are dignified, calm cats that prefer to keep all four paws on the ground — they are not typically lap cats and may resist being picked up. They are affectionate on their own terms, loyal to their families, and generally tolerant of well-behaved children and other pets. Their unflappable, easygoing nature makes them one of the most popular companion breeds worldwide.

Pros

Robust health and impressive longevity — commonly lives 14–20 years
Low-maintenance temperament — calm, quiet, and not prone to behavioral issues
Dense plush coat is easy to groom with weekly brushing
Handles being alone well — ideal for working professionals

Cons

Highly prone to obesity — requires strict diet management and play encouragement
Can develop hypertrophic cardiomyopathy (HCM) and polycystic kidney disease
Not a cuddly lap cat — prefers to sit near you rather than on you
Slow to mature — takes 3–5 years to reach full physical development

About the Selkirk Rex

The Selkirk Rex originated in Montana in 1987 from a single curly-coated kitten found in a shelter litter and later crossed with a Persian. Unlike the Cornish Rex and Devon Rex, the Selkirk Rex has a full, plush coat of loose, tumbling curls — including curly whiskers. This is a medium-to-large cat weighing 6–16 pounds with a round head, full cheeks, and a sturdy, muscular build. They come in both longhair and shorthair varieties, in every color and pattern, with the longhair displaying the most dramatic ringlets.

Temperament & Personality

Selkirk Rex cats are patient, laid-back companions with a goofy, playful streak that persists into adulthood. They enjoy being held and cuddled but are not overly demanding of attention — content to amuse themselves when their humans are busy. Their tolerant nature makes them wonderful with children and other pets.

Pros

Unique, teddy bear-like curly coat that is irresistibly soft to the touch
Patient and tolerant — excellent choice for families with young children
Easygoing and adaptable to various living situations
Less intense grooming than expected — curls should not be over-brushed

Cons

Curly coat can trap oils, requiring regular bathing to keep skin and fur healthy
Prone to polycystic kidney disease and hypertrophic cardiomyopathy from Persian heritage
Shedding can be significant — curly fur catches on furniture and clothing
Over-brushing straightens the curls, requiring a delicate grooming approach
