Female cats usually go into heat after they reach sexual maturity. Generally speaking, the age of sexual maturity of female cats is between 6 months and 1 year old, depending on the breed and individual differences.
When female cats enter estrus, they will exhibit a range of behavioral and vocal changes. Among them, the cry in estrus is one of the more obvious features. During estrus, female cats emit high-frequency, continuous, and loud meows to attract the surrounding male cats.
The estrus call is usually a melodious, sustained call that sometimes sounds like a cry or moan. These calls may be especially frequent at night because cats are more active at night.
It is worth noting that different cats may have different manifestations of estrus calls. Some female cats may meow very loudly, while others may be relatively quiet. In addition, some female cats may also show other behavioral changes during estrus, such as changes in body posture, wagging their tails, looking for male cats, etc.
If your female cat goes into heat and makes unusual noises, it is recommended to consult a veterinarian for more information and advice, especially if you do not intend to breed her or has already had her neutered.
