The litter prevalence of feline dystocia was investigated using a questionnaire survey of cat breeders. Information was obtained on 2928 litters, from 735 queens. Dystocia was reported to have occurred in 5.8 per cent of litters. The level of dystocia in individual breeds ranged from 0.4 per cent of litters born in a large colony of cats of mixed breeding, to 18.2 per cent of litters in the Devon rex. Pedigree litters were at significantly higher risk than litters of cats of mixed breeding (odds ratio: 22.6). Relatively high levels of dystocia were identified in Siamese-type, Persian and Devon rex litters, whereas cats of mixed breeding showed a relatively low litter prevalence. Dolicocephalic and brachycephalic types were found to have significantly higher levels of dystocia than mesocephalic cats.
通过对猫繁育者进行问卷调查，研究了猫难产的窝产患病率。收集了来自735只母猫的2928窝猫的信息。据报告，5.8%的窝出现了难产情况。各个品种的难产水平有所不同，从一个大型混种猫群体中出生的窝产猫中0.4%出现难产，到德文卷毛猫中18.2%的窝出现难产。纯种猫窝出现难产的风险显著高于混种猫窝（优势比：22.6）。在暹罗猫类型、波斯猫和德文卷毛猫窝中发现相对较高的难产水平，而混种猫窝的窝产患病率相对较低。发现长头型和短头型猫的难产水平显著高于中头型猫。
