OBJECTIVES: The aim of this study was to describe the incidence of feline @entity1266 with respect to breed. METHODS: The data used were reimbursed claims for veterinary care insurance and/or life insurance claims in @entity468 registered in a Swedish insurance database from 1999-2006. RESULTS: The incidence rates for @entity1266 were about 22 @entity468 per 10,000 cat years at risk, 67 per 10,000 for purebred @entity468 and seven per 10,000 for domestic shorthair @entity468 . The median age was 2.5 years. A significant effect of breed was seen. An incidence rate ratio (IRR) that was significantly higher compared with other purebred @entity468 was seen in the British Shorthair (IRR 2.5), the Oriental group (IRR 2.2), Birman (IRR 1.7), Ragdoll (IRR 1.5) and the Abyssinian group (IRR 1.5). A significantly lower IRR was seen in the Norwegian Forest Cat (IRR 0.38), the Maine Coon (IRR 0.48), the Persian/Exotic group (IRR 0.49) and the Cornish Rex (IRR 0.50). No common factor among the high-risk breeds explained their high risk for @entity1266 . There was no effect of location; that is, the incidence rate did not differ depending on whether the cat lived in an urban or rural area. Caesarean section was performed in 56% of the @entity468 with @entity1266 , and the case fatality was 2%. CONCLUSIONS AND RELEVANCE: The incidence rate for @entity1266 was of a similar magnitude in purebred @entity468 as in @entity235 . The IRR varied significantly among breeds, and the main cause for @entity1266 should be identified separately for each breed. A selection for easy parturitions in breeding programmes is suggested.
