Abstract: The objective of this study is to provide baseline data on mortality in purebred kittens in catteries. Data were collected from a software dedicated to cattery management (Breeding Management Support ®, BMS, Royal Canin, Aimargues, France). Informations were anonymously recorded from 1401 breeders and intererts to 6964 pregnancies from 4466 queens (18 breeds) and 27482 kittens. Mean litter size was 3.9 ± 1.9 kittens. The overall pre-weaning mortality rate was 15,5%, including 8,3% of stillborn kittens. Among the kittens alive at birth, 7,9% died before weaning. Statistical analyzes permitted to identify an effect of breed and litter size on kitten’s mortality. The post-natal mortality and the global mortality were also influenced by age of the queen at mating. All mortality races are not impacted by mating season, age at mating of the tomcat and gestation length. The productivity at the different breeds studied highlights differences in terms of reproductive performance between races Siberian, Ragdoll, Maine Coon, Norvegian, Russian Blue, Oriental, Chartreux, the most productive breeds and Turkish Angora, Bengal, Sphynx, Selkirk Rex, British Shorthair, Birman, Scottish, Devon Dex, Asian, Persian, Abyssinian
