So, it was a surprise when I bumped into a survey of 1978 (yes thirty years ago, things have probably changed a bit since then). The survey was carried out by RC Povey, who at the time worked at the Department of Clinical Studies, Ontario Veterinary College, Guelph, Ontario. The article was published in THE CANADIAN VETERINARY JOURNAL in August 1978.
The purpose of the survey was to investigate reports from veterinarians in North America that Purebred Pedigree Cat Breeders were experiencing a problem in breeding. The problem was as I understand it the frequency and size of litters - a "reproductive failure problem". They were low or lower than before it seems.
Does anyone have any knowledge of the expectations of cat breeders currently on this topic?
Mr Povey sent out 105 questionnaires, that were quite wide ranging, to breeders in Canada and the United States. 29 returned complete records implying some were returned incomplete. That represents a 28% success/return rate. Considering anyone doesn't much like filling in forms that isn't too bad really. The vast majority responding were located in Canada.
I have picked out the information that interests me (& hopefully any the odd visitor who might wander by) and it is presented in a table below. Some breeders didn't keep good enough records to complete the questionnaire. It shows that the average litter is about one per year. This is done deliberately by cat breeders for the sake of the queen cat and careful and considerate cat breeding.
Desmond Morris in his celebrated book, "Cat Watching" says that the European Wildcat has one litter per year and 2-4 kittens while the domestic cat may produce 4-5 kittens in each of the three litters per year.

This is not a knock cat breeders post. It is simply posting information about cat breeders which some people might find interesting. I certainly did as it is rare to see this sort of information.
