Normal feline reproduction: The queen

Abstract

Practical relevance: Cats are seasonally polyestrous, meaning they exhibit multiple estrous cycles within a season, followed by a period of non-cyclicity. Cats cycle when the day length is long but can be induced to cycle year-round with 14 h of continuous artificial lighting. The feline estrous cycle includes the following stages: proestrus, estrus, interestrus and, if ovulation occurs, diestrus. Cats are induced ovulators and ovulate in response to multiple natural matings. Successful breeding in a cattery requires knowledge of the female’s reproductive cycle, behavior and management, and often improper management can be the sole cause of infertility. Aim: The aim of this review is to provide readers with an overview of normal anatomy, cyclicity, management and behavior of the queen. It includes a series of questions veterinarians can ask to obtain a baseline knowledge of the management of the specific breeding set-up. Evidence base: The information in this article is based on the author’s experience, as well as drawing on historical and current literature, and provides the most up-to-date review as possible.
