There may be a reason why the cat is rolling on the ground and meowing. One possibility is that the cat is in estrus. If it is a female cat, it will mainly make miserable sounds at night, while male cats may urinate randomly. Generally speaking, a cat's estrus period usually lasts about 7-10 days. To solve this problem, you can choose to sterilize the cat; secondly, if the cat has fleas, parasites, or abdominal pain and other illnesses, it is recommended that pet owners deworm the cat regularly. If you suspect abdominal pain, you need to seek medical treatment as soon as possible.
