About the British Longhair

The British Longhair grew out of British Shorthair breeding programmes, particularly where Persian cats were used after the World Wars to rebuild numbers and broaden the gene pool. Long-haired kittens resulting from those crosses were eventually recognised as a breed in their own right. It has the sturdy body and round face of the British Shorthair, with a thick semi-long coat.

Temperament

Calm, undemanding and quietly affectionate. Like its shorthaired relative it prefers to sit beside people rather than be carried around, and it copes well with being left for a working day.

Play & activity

Low to moderate needs. Short play sessions with chase toys keep it from becoming sedentary.

Grooming

The dense semi-long coat can tangle, especially in moulting seasons. Brush two or three times a week and comb through the ruff and britches.

Care & wellbeing

Prone to weight gain, so meal control matters. Polycystic kidney disease and hypertrophic cardiomyopathy are conditions associated with the British and Persian lines it comes from.
