In the pro-oestrous stage of the cat’s oestrous cycle, the queen may start showing the first pro-oestrous behaviours, and these could start as early as four months of age. These behaviours include being more vocal than usual, restless and having an increased appetite. She may also show behaviours such as rolling on the floor and rubbing against objects.
During this stage, the ovaries start to form follicles. Unlike in dogs, the vulva of the queen will only enlarge slightly and will appear slightly moist, but will not discharge. The follicle stimulating hormone, oestrogen and other hormones will help the development of the egg in this stage.
This stage of the cycle usually lasts for around one to two days.

If the cat does mate, luteinising hormone (LH) will be released, which will stimulate ovulation.
Metoestrous and dioestrous
The next stages of the cycle is metoestrous and dioestrous. During this stage, the cat will not accept males to mate with and her behaviour will return to usual. Unlike other males, which continue to ovulate if they do not mate, cats will no longer ovulate if they do not mate as they are induced ovulators.
If the cat mates and is fertilised, progesterone is produced and released by the corpus luteum. If the queen is not fertilised, the corpus luteum will still release progesterone, however the levels of this hormone will reduce more rapidly than during …show more content…
Rather having five different stages of the oestrous cycle like cats, horses only have two stages of their oestrous cycle- oestrous and dioestrous.
Oestrous
The oestrous stage of the cycle can last anywhere between four and ten days, but usually averages at around six days. During this stage, the pituitary gland is influenced by the increased daylight during spring, which begins the production of follicle-stimulating hormone. This hormone gets released into the blood and travels to the ovaries, beginning the development of a follicle that contains an ovum. This produces oestrogen, which is released into the blood stream.
Luteinizing hormone then causes the ovary follicle to rupture, resulting in ovulation. When the follicular wall ruptures, it carries the ovum out with a fluid.
Mares will show behaviour during the oestrous stage of the cycle to try and attract a stallion to mate with. This behaviour includes raising their tail, squatting, frequent urinating, exposing the clitoris, and allowing copulation.
