This cycle will continue for several heat cycles or until she is bred. The period of time that she is out of heat will vary depending on geographic and environmental factors, such as temperature and the number of daylight hours. The signs of heat are different in cats as compared to dogs. Cats have minimal vaginal bleeding, usually not even enough to be detected. Their behavior is the most notable sign.
Cats become very affectionate.
They rub against their owners and furniture and constantly want attention. They roll on the floor. When stroked over the back, they raise their rear quarters into the air and tread with the back legs. They also become very vocal. These behavior changes often become obnoxious to owners and may be interpreted as some unusual illness.
