How does a cat's heat end? - briefly
A cat's heat cycle ends naturally after a period of 4 to 10 days if she does not mate, and it may recur every 2 to 3 weeks until breeding occurs or the season changes.
How does a cat's heat end? - in detail
A cat’s heat cycle, also known as estrus, ends when the hormonal changes in the feline’s body complete their natural course. During estrus, a female cat experiences a surge in estrogen levels, which triggers behaviors such as increased vocalization, restlessness, and seeking attention from male cats. If the cat does not mate and become pregnant, the estrogen levels gradually decline, signaling the end of the heat cycle. This process typically lasts between 4 to 10 days, but it can vary depending on the individual cat and environmental factors. Once the estrogen levels drop, the cat’s behavior returns to normal, and she no longer displays signs of being in heat. If the cat mates and fertilization occurs, the heat cycle ends as the body shifts its focus to pregnancy. In some cases, if the cat does not mate, she may enter a brief period of rest called diestrus before the cycle repeats. The frequency and duration of heat cycles can be influenced by factors such as breed, age, and overall health. Spaying is the most effective way to permanently prevent heat cycles in cats.
