Q: Can a cat get pregnant while still nursing kittens?

A: Yes. Lactation (production of milk) does not suppress the heat cycle, and cats that are actively nursing kittens can go into heat as soon as two weeks after giving birth.

Some aspects of a cat’s reproductive capabilities are truly remarkable. Did you know that even being pregnant doesn’t necessarily suppress the heat cycle in cats! In fact, 10 percent of female cats go into heat between the third and sixth week of pregnancy. Although these cycles are rarely fertile, it actually is possible for a cat to be carrying fetuses of different ages, resulting from separate matings in different heat cycles! The scientific term for this is "superfetation."

Also, a female cat in heat can mate with several males, and it is possible for kittens in a litter to have different fathers. The technical term for this is "superfecundation." Cats long have been recognized for their fertility. Bastet, the Egyptian goddess of fertility, is depicted as a cat in artwork, and the ancient Egyptians worshipped cats as a symbol of fertility. When it comes to making babies, cats are one of the most prolific domestic pets out there.

I did not know this about a mommy being able to go into heat while nursing kittens. Wow, I wish I had read the article before. I maintain a colony of about 12 feral cats, 2 newer unfixed males. A friendly female started coming around in November, she has 4 times had kittens. In May she had 6 kittens. 5 were killed by opossum's. I lock her & kitten up @ night. I have been trying to get her in for spaying, but I now believe she is again with kittens. Not sure if I should wait till kittens are born or have her aborted. How hard is this on Females? Any answers?

What I didn't see in article is; if cat is pregnant & then has another heat cycle during pregnancy does the second set of kittens get born prematurely when she goes into labor with first set?
