Ragdoll

origin: United States · 37 figures in the corpus · Q42688

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

10.31 years (life expectancy at age 0) verified

Ragdoll: years (life expectancy at age 0) (Teng KT, O'Neill DG, Brodbelt DC, Church DB, Pegram C)

  • Study sample n=69.
10.1 years (median age at death) verified

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

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

Ragdoll: 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.
