Solutions for cats that do not give birth on the due date:

1. You can take the cat to the pet hospital for further observation to prepare for the cat to give birth at any time.

2. If the cat has not given birth after observation, you can inject oxytocin into the cat to make the cat give birth.

3. If there is still no birth, pay attention to check whether the cat's fetus is normal and whether it is stillborn. If so, the stillborn fetus should be removed in time to avoid putting the female cat's life in danger.

The reasons why cats do not give birth on the due date:

1. It may be that the fetus carried by the cat is too large and the fetus is not delivered normally by the due date.

2. It may also be caused by an error in calculating the date. The estimated due date of a cat is 58 to 63 days after mating.

3. It is also possible that the fetus carried by the female cat is stillborn, resulting in the fetus not being born until the due date.

4. It may also be that the cat encounters dystocia, which may lead to this situation.
