Breeding Timing to Maximize Fertility in Cats

Breeding timing refers to a technique that may be utilized to ensure conception in cats by the purposeful timing of insemination during the estrus (heat) period. A fertile female cat is referred to as a queen.

Symptoms and Types

In order to maximize the odds of conception with properly timed breeding, it is best to pin-point, as close as possible, the day of ovulation for the queen. Symptoms of estrus in the queen are evident by her rubbing against objects, being vocal (much more than usual), and an interest shown by the male cat. However, timing of breeding is less critical with cats and ultimately depends on the amount of luteinizing hormone (LH) released, which is triggered via stimulation of the queen’s vagina and cervix.


Breeding timing and related fertility-maximizing techniques may be utilized for a number of reasons. This may be deemed necessary if there is an apparent failure to achieve conception in the queen.


For cats, the most reliable method of determining the ovulation cycle is by progesterone testing.
