How the Cat Pregnancy Calculator Works
The healthy due date of your cat is actually a range between 58-71 days after mating. The average cat pregnancy length is 63 days or 9 weeks. This cat pregnancy calculator estimates the earliest possible delivery as well as the latest possible delivery.
How Do I Know that my Cat is Pregnant?
If you suspect that your cat is pregnant, look for the following signs that indicate common physical and psychological changes during pregnancy:
- Increase of appetite
- Weight gain
- Swelling of nipples
- Rose-colored nipples
- Enlarged abdomen
- Affectionate behavior
If you suspect that your cat is pregnant, but you want to be sure, you can seek out an official diagnosis from a veterinarian. A vet can also check whether your cat is in good condition which is extremely important to know about during pregnancy.
Your vet may diagnose your cat through palpation. They can check for fetuses by palpating and gently pressing on your cat’s abdomen. This can be done during the 17th to 25th day of pregnancy.
Alternatively, you can get them an ultrasound to detect fetuses as early as the second week of your cat’s pregnancy. After the third week, an ultrasound may detect heartbeats.
One last option is X-rays. Your vet takes a radiograph of your cat’s abdomen once further along in their pregnancy. X-rays can help determine how many kittens your pregnant cat is carrying. The minor amount of radiation found in X-rays will not harm the mother or the kittens. After 42 days of pregnancy, their spines and skulls will be visible on X-rays.
