   Age at death and cause of death of pet rabbits (Oryctolagus cuniculus) seen at an exotic animal clinic in Tokyo, Japan: a retrospective study of 898 cases (2006–2020)

   Thống kê

   Median age at death of 898 pet rabbits was 7 years (IQR 5–9); 18% lived beyond 9 years

   Trích đoạn

   “"The median age at death was 7 years (interquartile range: 5 to 9 years), and 18% of all rabbits lived beyond 9 years. The main causes of death included neoplasia (n = 223; 24.8%), gastrointestinal disease (n = 135; 15.0%), bacterial abscess (n = 90; 10.0%), urinary disease (n = 85; 9.5%), trauma (n = 44; 4.9%), and cardiac disease (n = 27; 3.0%)." ”

   Median lifespan of 7 years from this peer-reviewed retrospective is the primary anchor for the central estimate. Applying an exponential survival model: λ = ln(2) / 7 ≈ 0.099 per year. P(rabbit dies within 4 years of acquisition) = 1 − e^(−0.099 × 4) = 1 − 0.671 ≈ 0.33. This population (clinic patients in an exotic-animal practice in Tokyo) likely overrepresents rabbits receiving better-than-average care, so 0.33 may be a slight underestimate relative to the average child's pet rabbit. Used as the lower anchor of the central estimate.

   How Long Do Rabbits Live?

   Thống kê

   Indoor house rabbits typically live 8–12 years

   Trích đoạn

   “"Indoor house rabbits typically live 8–12 years, depending on their size, breed, and the quality of care they receive. A well-cared-for house rabbit that has been spayed or neutered early in life has a life expectancy of 8 to 12 years." ”

   Under ideal indoor care (spayed/neutered, optimal diet), median lifespan is approximately 10 years. Applying exponential survival: λ = ln(2)/10 ≈ 0.069 per year. P(dies within 4 years) = 1 − e^(−0.069 × 4) ≈ 0.24. This represents the lower bound of the uncertainty range — best-case indoor care. The 12-year upper end of HRS's range gives λ = 0.058, P(4 years) ≈ 0.21. The 8-year lower end gives λ = 0.087, P(4 years) ≈ 0.30, consistent with the central estimate. Difference between HRS guidance and clinical studies likely reflects selection bias in both directions: HRS population are committed rabbit owners; clinic patients skew toward unwell rabbits.

   Morbidity and mortality of domestic rabbits (Oryctolagus cuniculus) under primary veterinary care in England

   Thống kê

   Median age at death among 370 rabbits that died during the study was 4.3 years (IQR 2.1–7.0, range 0.1–14.4)

   Trích đoạn

   “"The median age at death of the 370 rabbits that died during the study was 4.3 years (IQR 2.1–7.0, range 0.1–14.4). For males, the median age at death was older (5.2 years, IQR 3.0–8.1, range 0.2–14.4) than for females (3.7 years, IQR 2.0–5.9, range 0.1–11.8)." ”

   The VetCompass UK figure of 4.3 years is the median age at death among rabbits that died during a 1-year observational window (2013) across 107 clinics — it is NOT a cohort survival median. It captures which rabbits were dying at the time of observation, which skews toward younger ages because older rabbits had not yet died. This number should not be read as "median lifespan = 4.3 years." The Japanese retrospective (7-year median) is a more direct measure of lifespan because it follows rabbits through to death. The UK study is included as independent corroboration of mortality patterns and cause-of-death data (flystrike, GI stasis, anorexia) rather than as a lifespan anchor. The UK study also includes outdoor rabbits, who have significantly shorter lifespans than indoor pets.
