Normal ovary with follicles showing follicular development.
The feline ovary is not located within a bursa like the canine. It is easily seen at the tip of each horn. During estrus, multiple small (2-5 mm) follicles will be present on both ovaries. Cats are induced ovulators. When mature follicles like these are present and a queen is mated LH is released and ovulation occurs within 48 hours later. It requires multiple mating episodes to induce ovulation.
