Is there a pregnancy test for cats? - briefly
Yes, there are pregnancy tests available for cats. These tests typically detect the feline chorionic gonadotropin (fCG) hormone in urine, similar to human pregnancy tests that detect human chorionic gonadotropin (hCG).
Is there a pregnancy test for cats? - in detail
Yes, there is a way to determine if your cat is pregnant. While there isn't a conventional at-home pregnancy test like those available for humans, veterinarians can perform several diagnostic tests to confirm feline pregnancy. Here are some of the methods used:
-
Palpation: Around 18-20 days after mating, your veterinarian can manually feel the cat's abdomen to detect kittens. This is similar to how human obstetricians examine pregnancies. The fetuses can be felt as small, firm lumps within the uterus.
-
Ultrasound: Starting from day 15-18 post-mating, an ultrasound can be used to visualize the developing fetuses. This non-invasive method provides a clear image of the uterus and any kittens present. It is particularly useful for determining the number of fetuses and their approximate ages.
-
X-rays: After day 40-45 post-mating, X-rays can be used to count the number of kittens in the uterus. The bones of the developing fetuses will appear as distinct shadows on the X-ray film. This method is less commonly used nowadays due to potential risks associated with radiation exposure.
-
Hormone Tests: Blood tests can be performed to measure progesterone levels. A rise in progesterone indicates that ovulation has occurred and the cat is likely pregnant. However, this test alone cannot confirm pregnancy; it needs to be coupled with other methods like ultrasound for accurate diagnosis.
-
Relaxin Test: Relaxin is a hormone produced by the placenta during pregnancy. A blood test can detect relaxin levels, which rise significantly after day 20 of pregnancy and peak around day 35. This test can be very useful in confirming feline pregnancy.
It's important to note that while these methods are generally reliable, false negatives or positives can occur. Regular veterinary check-ups throughout the pregnancy ensure the best care for both the mother cat and her kittens. Always consult with a qualified veterinarian for advice tailored to your specific situation.
