The reasons why cats roll after mating:

1. It may be because the female cat prevents the sperm from flowing out and allows the sperm to better combine with the egg to successfully mate.

2. It may also be caused by the special barbs on the male cat’s genitals and the male cat biting the female cat’s neck during mating, which causes the female cat to suffer and cause rolling.

3. It is also possible that the female cat is rolling due to pain caused by other diseases.

Precautions after mating:

1. After mating, the cat should be locked up alone to prevent the cat from being grumpy and causing fights.

2. After the cat has mated, it is necessary to clean the area around the cat’s genitals in time to keep it clean.

3. After mating, you also need to pay attention to the cat's physical and mental conditions. If there are any abnormalities, take the cat to the hospital for examination in time.
