How to Tell If a Cat Is Pregnant Early Stages?
Pregnant cats may occasionally get sick and vomit. However, like humans, not all cats have morning sickness. Besides morning sickness, cats often lose their appetite due to nausea, but they usually regain appetite after the third week of pregnancy. If the cat vomits, be sure to pay attention to it. If vomiting occurs frequently, consult your veterinarian.
Swelling of Abdomen
With the kittens growing inside the mother cat, its tummy will start to swell. Avoid touching it so you don’t risk hurting the cat and its unborn kittens. Abdominal swelling can be caused by other conditions also, so it’s encouraged to monitor your cat for any other signs of illness.
Pregnant cats increase their appetite in the later stages of pregnancy, which will help their weight gain. This is most noticeable on the cat's side, where fat deposits usually occur. During pregnancy, it will gain about one or two pounds per day.
The normal weight gain of a cat during pregnancy is 20% to 30% of the total weight of the cat. If your cat is below or above the threshold, go to the vet immediately.
