In general, a pregnant cat who is receiving all the necessary care (not only water and food, but also a lot of love and company) does not have to have difficulties giving birth to her puppies, but unfortunately there is always a risk that not everything goes as expected.
It is for this reason that I am going to tell you what are the possible complications in the birth of a cat so you can spot the signs that indicate a problem.
Spontaneous abortion
Both during pregnancy and during childbirth, there is the possibility that the cat suffers a spontaneous abortion of some or all of the pups. This, in principle, should not worry us, but if the fetus is not expelled it could cause a serious infection.
Dystocia
Dystocia it is the difficulty that the offspring find to cross the mother's birth canal. It usually occurs when the litter is very large, or when the head of the furry ones is large, such as that of the Persians.
Fever
When a body is fighting disease, its body temperature increases. Therefore, we can know, or at least intuit, that the delivery is not going as it should if the cat has a fever, that is, if from the 60th day of pregnancy the temperature is more than 36,5ºC (before and after after delivery will be 38ºC).
Hemorrhages
If the pregnant cat bleeds, it is usually because a complication has arisen. Therefore, if the blood is very dark and the bleeding continues beyond a few minutes, you probably have a serious problem, such as a ruptured uterus.
Interruption of labor
Normally, the hatchlings come out in a time interval that is usually 20 minutes. If this period lasts four hours or more, then both the lives of the cat and the offspring are in danger..
Dark liquid
When the cat is in the expulsion phase of her puppies, if she begins to expel a dark and viscous liquid that gives off a very unpleasant smell it may be because there is a dead baby in its belly or because it has an infection.
If you suspect that your cat and / or her pups are not well, do not hesitate to take her to the vet.
