During their heat cycle, cats, especially females, will emit a cry similar to a baby's cry to attract mates. This crying may be more frequent at night. During this time, cats may also exhibit behaviors such as being particularly clingy, rubbing against others, and raising their rear ends when petted.

When cats have physiological needs, such as thirst, hunger, or wanting to play, they may make sounds similar to a child crying to attract their owner's attention.
If a cat frequently makes this kind of meowing, accompanied by symptoms such as lethargy and loss of appetite, it may be sick. Its discomfort or pain is causing it to keep meowing.
