Cats generally go into estrus when they are 6-10 months old, about 3-4 times a year, with an average estrus duration of about 7 days, mainly during the alternation of seasons.

First of all, a cat's estrus is affected by changes in hormone levels in the body, and this situation occurs periodically. Secondly, the main symptoms of cats in estrus include restlessness, walking back and forth, increased frequency of urination, howling, and extreme desire for cats of the opposite sex. Finally, the clinical measure to prevent cats from going into heat is sterilization. It is not recommended to suppress cats from going into heat by feeding them drugs.
