When stroked over the back, they raise their rear quarters into the air and tread with the back legs. They also become very vocal. These behavior changes often become obnoxious to owners and may be interpreted as some unusual illness. In addition, queens in heat attract unneutered male cats. Tom cats that have never been seen will appear and attempt to enter the house to get to the female.
Male cats are more successful breeders in familiar surroundings.
Therefore, it is preferable to take the female to the male's home for breeding. The timing for breeding cats is not highly critical or complicated because cats are induced ovulators. This means that the act of breeding stimulates the ovaries to release eggs. Therefore, the female's eggs should be released from the ovaries when the sperm are deposited in the reproductive tract at breeding. Most female cats require 3-4 breedings within a 24 hour period for ovulation to occur.
