How to tell if a cat is in heat? - in detail
Determining whether a cat is in heat involves recognizing several behavioral and physical changes that occur during this phase of her reproductive cycle. The signs of estrus, or "heat," can be quite distinctive once you know what to look for.
Behaviorally, one of the most apparent indicators that a cat is in heat is an increase in vocalization. She may become more vocal and meow excessively, often with a distinct, plaintive cry that differs from her usual meows. This vocalization can be persistent and may occur throughout the day and night.
Another significant behavioral change is increased affection and rubbing against people or objects. The cat may roll on her back, raise her hindquarters in the air, and tread with her back feet, a behavior known as "lordosis." This posture is an invitation to mate and is a clear sign that she is in heat.
Physical changes also accompany a cat's heat cycle. The vulva may appear swollen or red due to increased blood flow to the area. Some cats might exhibit a slight discharge from the vulva, which can range from clear to slightly bloody or mucous-like.
Additionally, cats in heat often experience a decrease in appetite and may eat less during this period. This is due to the hormonal changes taking place in her body.
The duration of heat in cats can vary, but it typically lasts between 4 to 10 days. If the cat does not become pregnant during this time, she will go out of heat and enter a period called "diestrus." After a few months, the cycle may repeat itself, with the cat going back into heat until she becomes pregnant or is spayed.
Understanding these signs can help owners recognize when their cat is in heat and take appropriate action, such as keeping her indoors to prevent unwanted pregnancies or contacting a veterinarian for advice on managing or preventing future cycles through spaying.
