Specific solutions to the problem of cats not giving birth for 66 days:

1. Cats give birth in an average of 63 days during pregnancy. The expected delivery date will vary depending on its breed, body shape, and nutritional status. There is a certain gap, generally a difference of 7 days is normal, so if you are not producing for 66 days, you can observe its condition for a few days.

2. You can observe whether the cat has fetal movement. If there is no fetal movement, stillbirth may occur, and the owner needs to go to the hospital for examination. If there is fetal movement, the owner can check whether the cat is lactating. Generally, cats will secrete lactation 3 days before giving birth.

3. Cats can be allowed to exercise appropriately, but no strenuous exercise is allowed. A certain amount of exercise can promote cat production and enhance its productivity.

4. If the fetus is too large, it may cause dystocia for the cat. It is best for the owner to take the cat to the hospital for further examination and decide whether to give an injection to induce labor based on the actual situation.

5. If the cat still shows no signs of giving birth beyond the expected date of delivery, or you are worried that the female cat will have difficulty giving birth, you can perform emergency caesarean section.
