Visual Differences

Telling a British Shorthair from a Persian

British Shorthairs have a similar round face and stocky build but a short, plush coat and a distinct muzzle — their nose has a visible indent (stop) but is NOT flat like the Persian’s brachycephalic snub nose.

British Shorthair Key Markers

  • Round head with full cheeks, short nose, and a visible stop between forehead and nose
  • Large, round copper or gold eyes (eye color depends on coat color)
  • Dense, plush double coat that stands away from the body — feels like thick velvet or wool

Persian Key Markers

  • Round, wide head with a short snub nose, full cheeks, and a visible stop — a brachycephalic (flat-faced) profile is the breed’s hallmark
  • Large, round, vivid copper or deep blue eyes set wide apart, giving a sweet, open expression
  • Long, thick, silky coat with a fine texture and a prominent ruff around the neck and chest

Temperament & Personality

British Shorthair

  • Calm and easygoing — prefers lounging to climbing or jumping
  • Affectionate but not needy; happy to share a room without demanding lap time
  • Good with children, dogs, and other cats — rarely aggressive
  • Quiet — does not meow excessively; communicates with soft chirps and glances
  • Slow to mature — takes 3–5 years to reach full physical and emotional development

Persian

  • Extremely calm and quiet — prefers serene environments over noise and activity
  • Affectionate and people-oriented but not demanding; happiest lounging nearby rather than on a lap
  • Low activity level — enjoys short play sessions but spends most of the day napping or observing
  • Gentle and patient with children and other pets — rarely scratches or acts out
  • Requires daily grooming — the long, fine coat mats easily without consistent brushing

Health Notes

British Shorthair

  • Hypertrophic cardiomyopathy (HCM) — genetic heart disease; regular cardiac screening recommended for breeding cats
  • Polycystic kidney disease (PKD) — inherited from Persian outcross ancestry; DNA testing available
  • Obesity — the breed’s low-energy, easygoing nature makes weight management a priority
  • Dental disease — brachycephalic facial structure can cause crowded teeth and gum issues
  • Hemophilia B (Factor IX deficiency) — a rare bleeding disorder known in some British Shorthair lines

Persian

  • Polycystic kidney disease (PKD) — an inherited condition causing kidney cysts; before DNA testing became widely available, 38% of Persians were affected; a simple DNA test can identify carriers
  • Brachycephalic airway syndrome — the flat face can cause breathing difficulties, tear duct overflow (staining), dental crowding, and heat sensitivity
  • Progressive retinal atrophy (PRA) — a retinal degenerative disease leading to vision loss; DNA testing available
  • Hypertrophic cardiomyopathy (HCM) — regular cardiac screening recommended for breeding cats
  • Feline lower urinary tract disease (FLUTD) — Persians have a higher predisposition to bladder stones and urinary tract issues
  • Dermatophytosis (ringworm) — the dense coat makes Persians more susceptible to fungal skin infections

Frequently Asked Questions

How can I tell a British Shorthair apart from a Persian?
British Shorthairs have a similar round face and stocky build but a short, plush coat and a distinct muzzle — their nose has a visible indent (stop) but is NOT flat like the Persian’s brachycephalic snub nose.
Are British Shorthairs hypoallergenic?
No — British Shorthairs are not hypoallergenic. They produce normal levels of the Fel d 1 allergen, and their dense double coat sheds a great deal of dander and fur. Their plush coat may feel wonderful, but it releases plenty of allergens into the home. Allergy sufferers should spend time with the breed before committing.
Are Persian cats hypoallergenic?
No — Persians are not hypoallergenic and are actually a challenging choice for allergy sufferers. They produce normal levels of the Fel d 1 allergen, and their long, fine coat traps and sheds dander and loose fur throughout the home. Daily grooming and regular cleaning help, but they do not remove the allergen entirely.
