British Shorthair

origin: United Kingdom · 6 figures in the corpus · Q29273

Every figure below carries this breed's name or id in its source study -- grouped by what it measures, not ranked. A breed appearing under a study here does not mean every other breed was tested and came back negative; it means this is what has a named source so far. See each figure's own page for its caveats.

Longevity

11.8 years (median age at death) verified

British shorthair: years (median age at death) (O'Neill DG, Church DB, McGreevy PD, Thomson PC, Brodbelt DC)

  • Study sample n=69.

386 deaths per 10,000 cat-years at risk (ASMR) verified

British Shorthair: age-standardized total mortality rate, Swedish insured cats (Egenvall 2009, Agria)

  • A rate, not a life expectancy -- higher ASMR means higher yearly death risk, not necessarily a shorter median lifespan.

  • Study sample n=110 litters.

  • Study sample n=110 litters.

Bodyweight

4.0 kg (adult bodyweight, Wikidata P2067) verified

British Shorthair: adult bodyweight

  • Wikidata mass is sparse and its own sourcing varies by item; treat as indicative, not a veterinary measurement. See bodyweight-vetcompass-* figures for breeds with a clinical-cohort measurement instead.

Category (FIFe)

3 FIFe category (1-4, coat/morphology grouping) verified

British Shorthair (BSH): FIFe Category 3

  • Category is a coat/morphology grouping FIFe itself uses, not a ranking (1=lowest number, 4=highest, no ordinal meaning).
