This situation should be caused by a male cat that has just been neutered. After the sterilization operation, the male hormones in the cat's body have not yet decreased, so it will ride the female cat. After a period of time, the androgen in the body is completely metabolized, and this situation will not occur. . If there are two cats at home, it is recommended to keep the two cats separately to avoid fighting between the two cats, and wait until the neutered male cat recovers before raising them together.
