If you are not sure whether the cat is really going to have a baby, or if there is something wrong with delivery, I suggest you consult a veterinarian or an animal care worker as soon as possible. Before waiting for the arrival of the veterinarian or nursing staff, you can prepare a quiet, warm and safe place for the cat, provide some food and water, and closely observe the situation of the cat.
When kittens are born, the mother cat will take care of them. However, you still need to pay close attention to the health status of mother cats and newborn kittens to ensure that they get proper care and nutrition. If you need more help, please consult a veterinarian or animal care worker.
