A cat's estrus is most directly related to its age. The most generally accepted statement is that cats are in peak estrus when they are 5-6 months old. Some cats will go into estrus when they are 4 months old, and some cats may not go into estrus until 10 or 12 months old. If the cat is alone, the estrus period will usually be later. If the cat lives with other cats of the opposite sex, the estrus period will usually be earlier. The earliest female cats are 4 or 5 months old, and the later ones can reach around 1 and a half years old. Male cats become sexually mature later than female cats, and start going into estrus around 8 months old.

How to deal with a cat in heat:

1. Let the cat stay in a warm place. A warm place can make the cat feel calm. Play with the cat more to divert the cat's attention. Soothe the cat and rub their back.

2. Keep the cat litter box clean. If a female cat urinates indiscriminately at home, she needs to clean it up to prevent the cat from attracting male cats with urine and leaving a mark. Encourage the cat to use the litter box instead of urinating indiscriminately.

3. During the cat’s estrus period, what you need to pay attention to is to remember to seal the doors and windows so that the cat does not have the opportunity to go out. There should be no gaps in the windows. Remember to keep the door open when you go out. Cats in estrus have a strong urge to go out to court, so be careful.

4. Neuter the cat. If the owner wants to avoid future troubles, he can directly perform sterilization surgery on the cat. However, the cat will no longer be able to have children in the future. However, the advantage is that sterilization can extend the cat’s life, change the cat’s personality, and reduce the occurrence of diseases.
