If it is a female cat, it may be in estrus. The female cat at home will roll around, act coquettishly, and cry at night when in estrus. At this time, the breeder who wants kittens can find a boyfriend for the female cat to mate with. It may also be that the cat has not seen you for a long time and is expressing its love and miss to you, and wants you to pet and accompany it. Cats’ bellies are fragile and they will not be exposed easily, only to familiar people.
