Abstract :

The ovary contains many differentiated cell types which control many physiological functions related to reproduction. Each follicle in the ovary consists of an oocyte and the surrounding specialized cells. Each of these follicles aim to develop into a healthy oocyte which can be ovulated. Unlike other animals, cats and rabbits have follicles which can ovulate just by vaginal stimulation. Cats are seasonally polyoestrous animals. The oestrous cycle is repeated during the mating season, unless pregnancy or pseudo-pregnancy occurs in cats. The changes that occur in the ovary during the oestrous cycle are grouped under two periods which are called the follicular and luteal phase. The aim of this review is to give a concise description of the general structure of the ovary, the hormonal control of reproduction, and the follicular and luteal phase in cats.
