Telling a British Longhair from a British Shorthair

The British Shorthair is the same cat in a short coat. It has a dense, plush coat that lies close to the body and feels like sheepskin; the British Longhair carries the same texture at medium length, with a ruff, britches, and a feathered tail. Head, body, and temperament are otherwise identical.

British Longhair Key Markers

  • Semi-long, dense coat that stands away from the body, plush and springy like the British Shorthair coat but long enough to form a ruff around the neck, britches on the hind legs, and light feathering on the tail; the coat thickens in winter and sheds heavily in spring
  • Round head with full cheeks, a short nose, and a visible stop between forehead and nose; the muzzle is round and broad with a distinct whisker break, the same sweet, open expression as the British Shorthair
  • Large, round copper or gold eyes (blue in colorpoint varieties), set wide apart

  • Affectionate on their own terms — enjoys being petted and sitting nearby, rarely insists on lap time
  • Quiet — communicates with soft chirps and glances rather than loud meowing
  • Good with children, dogs, and other cats — patient and rarely aggressive
  • Slow to mature — stays playful and kittenish until 3 to 5 years old
  • Low to moderate energy — enjoys short play sessions, then settles into long naps

Health Notes

British Longhair

  • Hypertrophic cardiomyopathy (HCM) — the most common inherited heart disease in the breed, shared with the British Shorthair; regular cardiac screening recommended for breeding cats
  • Polycystic kidney disease (PKD) — inherited from Persian outcross ancestry; a DNA test identifies carriers
  • Obesity — the low-energy, easygoing nature makes weight management a lifelong priority
  • Dental disease — the broad muzzle can crowd the teeth and raise gingivitis risk; regular dental care recommended
  • Hemophilia B (Factor IX deficiency) — a rare bleeding disorder documented in British lines; responsible breeders test before breeding
