For females of all animals , the cyclical nature of sexual behavior is characteristic. Its general regulation is carried out by a part of the brain called the hypothalamus, which reacts both to changes in the body (the level of hormones, for example) and to changes in the surrounding world (in particular, to the length of daylight hours).

The task of the hypothalamus is to prepare the animal for mating, pregnancy, childbirth and to ensure the normal performance of dormant functions. The hypothalamus does this by controlling the secretion of hormones by the pituitary gland (located at the base of the brain), which in turn influences the secretion of the hormones estrogen and progesterone.

In cats, the period of sexual inactivity (anesterus) is an average of four months. Passivity is associated with the shortness of daylight hours (less than 12-14 hours a day) and (to a much lesser extent) with a decrease in temperature. Consequently, cats kept in artificially lit houses may either not have this period or be very short.

During the year, cats usually have 2-3 peaks of sexual activity; in the Northern Hemisphere, this time falls in the intervals from early spring to early summer and from late summer to late autumn.

The esteroid cycle begins with a preparatory stage (called proesterus), during which the cat is often very affectionate but restless and reluctant to have sexual intercourse. The cat walks around the room, often rubs against furniture and can roll on the floor. She often urinates more than usual. Unlike dogs, cats at this time slightly swell the vulva, but there is no discharge from the vagina. After 1-3 days, esterus begins, and at this time the cat prepares for mating.

The signs described above are intensified. The animal rolls on the floor, emitting characteristic howls, which are usually called calling. Siamese cats howl especially shrilly. The animal's behavior is so dramatic that the owners who see this for the first time usually think that the cat is in severe pain, and immediately run to the veterinarian. If you stroke a cat, it immediately becomes in a position for mating (it takes the same position in the presence of a cat): the front legs are bent, and the back of the body is raised, so that the back is concave. The tail is pressed to the side and the cat, leaning to the floor, makes trampling movements with its hind legs.

The cat can reject food and water everything around with urine. If locked, she may stubbornly try to escape into the street. Even if these signs are not very noticeable to you (and this happens if the cat is about to mate for the first time), the neighbour's cats will undoubtedly figure out what the matter is and begin to gather around your house.

Unlike most mammals, a cat's ovaries do not release eggs (this is called ovulation) unless the cat has mated. In this respect, cats are similar to rabbits, ferrets and minks. Ovulation occurs 24 to 36 hours after mating.

If mating occurs, then within 1-2 days all signs of esterus disappear. If not, then "heat" lasts 10-12 days. If the result is pregnancy, then further sexual activity is not observed, and if not, then after the esterus comes a period of "calm" (diesterus), and after 7-12 days, signs of proesterus reappear, marking the beginning of a new peak. Thus, the esteroid cycles are repeated after about 21 days. The older the cat, the shorter the cycle.

Cycle. In 12% of cats, and especially in Siamese cats, there is no diesterus (the interval between periods of passion); animals can emit calling cries and have sexual intercourse continuously for 6-10 weeks. This phenomenon is called nymphomania and can be very uncomfortable for the owner.

Cats do not have pronounced mating seasons, and they seem to be ready to mate all year round, although in fact their activity increases in spring and decreases in winter. This is undoubtedly due to the presence or absence of females willing to have sexual intercourse.
