Cat Forum / Health and Behavior / March 2005Is this true?
I read this on another newsgroup. Someone said cats continue to go into heat every three weeks while they are pregnant, and conceive another litter. I've never fostered a pg momma cat, the ones I've had already gave birth. My fellow fosterers say that pg cats get cranky, but no one's ever said they go into heat.

Rabbits don't have a estrus cycle, unlike most mammals. They CAN carry two litters of differing ages. http://www.admani.com/AllianceRabbit/Reproduction.htm Signature-- ~kaeli~ Experience is something you don't get until just after you need it. http://www.ipwebdesign.net/wildAtHeart http://www.ipwebdesign.net/kaelisSpace > Apparently rabbits have two utueruses and can go into heat while pregnant, > carrying two litters at a time! The uterus is duplex with separate cervical and uterine openings. But there's only one. They also don't go into heat or have estrus cycles. They ovulate upon copulation and if they carry two litters from different fathers, they tend to be birthed together and the younger litter dies.

Well, there you go! > Mammals cannot go into heat if they are pregnant. Thanks. I didn't think this was true, just wanted to check.

MaryL > I read this on another newsgroup. Someone said cats continue to go into > heat every three weeks while they are pregnant, and conceive another litter. No, they can't. Part of the estrus cycle strips out the uterine lining (like menses in human females). It would kill developing kittens. But they CAN conceive from two different fathers at the same time and they can conceive almost immediately after birthing their litter.

Most do not ovulate during pregnancy, but I stand corrected on it being possible. http://www.catclinic.co.uk/health/pregnancy.htm SUPERFETATION: A small percentage of queens can ovulate during pregnancy and if they mate this can result in pregnancy with kittens of different ages.
