This may be the sound made by two male cats fighting for territory, or it may be the sound made by a cat in heat. Parents can go out to stop them from fighting for territory. If the cat is in heat, parents will not let it mate. It is best to neuter the cat as soon as possible to avoid reproductive system diseases caused by long-term estrus.

Tip:

Urinary tract diseases in male cats are often caused by estrus. Parents should neuter male cats as soon as possible when raising them.
