Unneutered cats have their strongest and most frequent heats from March to May. In female cats living mainly indoors, this timing becomes less distinct, mostly because of lighting that remains on for much of the day and throughout the year. Therefore, indoor cats do not have specific periods when heat occurs.
Heat in a Female Cat – How Can It Be Recognized?
The reproductive cycle of female cats consists of four stages:
- proestrus (duration: approximately 1–3 days)
- estrus
- interestrus
- a period of inactivity.
A female cat’s proestrus is characterized by specific purring and meowing, frequent urination, rubbing against furniture and other objects, and rolling on the floor. Importantly, during this time the female does not allow a male to mate with her.
After approximately three days of proestrus, the so-called estrus begins and lasts about one week. Interestingly, long-haired cats have shorter heats than short-haired cats. During estrus, the female allows a male to approach her. Mating usually shortens her heat, although it can also happen that she allows other males to mate with her. Female cats also have so-called induced ovulation, meaning that the egg is released only during mating. Kittens from a single litter may therefore have several fathers. In addition, the act of mating itself is very painful for the female.
Throughout the entire period of heat (https://zwierzaki.pl/ruja-u-kotki), the female cat is exceptionally restless, highly agitated and nervous. This state continues around the clock and causes disturbances in physiological functions and appetite.
It is worth bearing in mind that the duration of a female cat’s heat, its symptoms and its effect on the animal’s behavior depend on the individual. Some female cats show no visible signs of heat but are ready to mate. Therefore, it is very important not to keep a male and female cat together if neither has been neutered, as this may result in an unexpected pregnancy, including among feline siblings.
Cats can be neutered as early as 3 or 4 months of age. Veterinarians also recommend performing the procedure as soon as possible, especially before the first heat.
How Long Does Heat Last in a Female Cat?
Heat in a female cat lasts from approximately one week to as many as ten days, although everything depends on the animal’s individual predisposition. In some females, this period may last up to one month. The interestrus period, in turn, lasts from 1 to 2 weeks, although there are also cases in which another heat appears after just a few days.
In addition, every heat increases the risk of reproductive-system disorders, various types of cancer and pyometra, a life-threatening condition. If a female cat is not neutered, heat will continue to occur for the rest of her life.
How Heat Affects a Cat’s Functioning
Heat itself is not extremely painful for the animal, but it is incredibly exhausting, not only for the cat but also for its owners. It is a period lasting from several to more than a dozen days, involving constant meowing, rolling and rubbing in an attempt to attract a male.
How Can You Help a Female Cat During Heat?
By far the best and, importantly, permanent solution is to neuter the female cat. Most veterinarians recommend neutering before the first heat so that the animal does not have to suffer. There are also medications that suppress heat, but in the long term they are harmful to her health and may additionally contribute to dangerous inflammation of the uterus, known as pyometra. Some medications that suppress heat in female cats also contribute to increased body weight and appetite. Heat is also very exhausting for a female cat, while persistent heat places a significant burden on her body.
