Abstract：
OBJECTIVE: The aims of the present study were to generate the first life tables for the UK companion cat population overall as well as broken down by sex and breed status, and to quantify associations between mortality and traits such as sex, neuter status, breed status and body weight in relation to mortality.
METHODS: Life table construction and modelling included data on 7936 confirmed deaths in cats under primary veterinary care at clinics participating in the VetCompass Programme in 2019. The life tables were built for cats overall, female and male cats, and crossbred and purebred cats. Multivariable generalised linear regression models were generated to explore the risk factors for a shortened lifespan.
RESULTS: Life expectancy at age 0 for UK companion cats overall was 11.74 years (95% confidence interval [CI] 11.61-11.87). The probability of death at each year interval increased with age from year interval 3-4, with the probability value not exceeding 0.05 before year 9. Female cats (12.51 years; 95% CI 12.32-12.69) had a 1.33-year longer life expectancy than male cats (11.18 years; 95% CI 11.01-11.38) at age 0. Among the 12 breeds (including crossbred) analysed, Burmese and Birman had the longest life expectancy at year 0, showing 14.42 years (95% CI 12.91-15.93) and 14.39 years (95% CI 12.87-15.91), respectively. Sphynx had the shortest life expectancy at year 0 among the analysed breeds at 6.68 years (95% CI 4.53-8.83). Being entire, purebred and with a non-ideal body weight were significantly linked to a decreased lifespan.
CONCLUSIONS: The life tables presented here for companion cats in the UK overall, by sex, and by crossbred and purebred cats can contribute to a better understanding of the life trajectory of cats, helping with evidence-based decision-making for cat owners and the veterinary profession. We have also provided an updated life expectancy at age 0 for various cat breeds for 2019 and showed evidence of the association between non-ideal weight and a decreased lifespan.

摘要：
目的：本研究的目的是为英国伴侣猫种群总体以及按性别和品种状况分类的第一生命表。并量化死亡率和性别等特征之间的关联，中性状态，品种状况和体重与死亡率的关系。
方法：生命表的构建和建模包括2019年参加VetCompass计划的诊所在初级兽医护理下的7936只确认死亡的猫的数据。生命表是为猫建造的，母猫和公猫，杂交和纯种猫。生成多变量广义线性回归模型来探索寿命缩短的危险因素。
结果：英国伴侣猫在0岁时的总体预期寿命为11.74岁（95％置信区间[CI]11.61-11.87）。从第3-4年间隔开始，每年间隔的死亡概率随年龄的增加而增加，在第9年之前，概率值不超过0.05。雌性猫（12.51岁；95％CI12.32-12.69）在0岁时的预期寿命比雄性猫（11.18岁；95％CI11.01-11.38）长1.33年。在分析的12个品种(包括杂交品种)中，缅甸和Birman在第0年的预期寿命最长，分别为14.42岁（95％CI12.91-15.93）和14.39岁（95％CI12.87-15.91），分别。在所分析的品种中，Sphynx在第0年的预期寿命最短，为6.68岁（95％CI4.53-8.83）。完整的，纯种和不理想的体重与寿命降低显着相关。
结论：这里为英国伴侣猫提供的生命表，按性别,通过杂交和纯种猫可以有助于更好地了解猫的生命轨迹，帮助猫主人和兽医行业的循证决策。我们还提供了2019年各种猫品种在0岁时的最新预期寿命，并显示了非理想体重与寿命下降之间关联的证据。
