Can you use a regular pregnancy test on cat?

No. You cannot use a pregnancy test meant for humans on a cat. Pregnancy tests detect the presence of a human hormone called human chorionic gonadotropin (hCG) in urine or blood. Cats do not produce this hormone, so a human pregnancy test will not give you an accurate result.

To determine whether a cat is pregnant, you should take her to a veterinarian for an examination. The veterinarian will be able to feel for the presence of kittens in the uterus and may also perform an ultrasound to confirm the pregnancy.
