猫人寿保险数据库可用于研究猫的死亡率。假设目的是描述瑞典猫的生命保险的死亡模式。所有1999-2006年期间购买人寿保险的猫（13岁以下）均被纳入研究对象。方法计算性别（男性和女性）、年龄、品种和诊断的标准化死亡率（MR）。不同年龄的存活率是按时间和品种来表示的。结果参保猫总数为49,450只，危猫年（CYAR）为142,049只。在此期间，有6,491只猫死亡，其中4,591只猫（71%）被诊断出患有疾病，即要求人寿保险。年平均MR为每10,000 CYAR 462例死亡（95%可信区间为431-493）。性别差异率无显著差异。波斯犬和暹罗犬的总体死亡率高于其他几个品种。在以2年为周期进行分析时，总体和品种特异性（大多数品种）的存活率随着时间的推移而增加。6种最常见的诊断类别（忽略未诊断死亡的猫）是泌尿、创伤、肿瘤、感染性、心血管和胃肠道。诊断类别内的MR因年龄和品种而异。结论及临床意义在以纯种保险猫为主的种群中，总体死亡率随年龄和品种而异，但不随性别而异。随着时间的推移，宠物猫存活率的增加可能反映了人们愿意养宠物猫更长时间，以及越来越多的兽医护理机会和复杂性。
BackgroundA cat life insurance database can potentially be used to study feline mortality.HypothesisThe aim was to describe patterns of mortality in life-insured Swedish cats.CatsAll cats (< 13 years of age) with life insurance during the period 1999-2006 were included.MethodsAge-standardized mortality rates (MR) were calculated with respect to sex (males and females), age, breed, and diagnosis. Survival to various ages is presented by time period and breed.ResultsThe total number of cats insured was 49,450 and the number of cat-years at risk (CYAR) was 142,049. During the period, 6,491 cats died and of these 4,591 cats (71%) had a diagnosis, ie, were claimed for life insurance. The average annual MR was 462 deaths per 10,000 CYAR (95% confidence interval, 431-493). Sex-specific rates did not differ significantly. The overall mortality of the Persian and the Siamese groups was higher than that of several other breeds. Overall and breed-specific (for most breeds) survival increased with time when analyzed by 2-year periods. The 6 most common diagnostic categories (ignoring cats recorded as dead with no diagnosis) were urinary, traumatic, neoplastic, infectious, cardiovascular, and gastrointestinal. The MR within diagnostic categories varied by age and breed.Conclusions and Clinical ImportanceIn this mainly purebred, insured cat population, the overall mortality varied with age and breed but not with sex. The increase in survival over time is likely a reflection of willingness to keep pet cats longer and increased access to and sophistication of veterinary care.
