I believe my cat is in labor but I do not know because I do not know when she conceived. Two days ago she discharged a mucusy substance from her vaginal area. She is around 2 years old and this is her first litter. She seems fine and is purring, calm, wagging her tail when she sees me and sleeping amongst the towels I have put in the tub for her. How long do I wait for the kittens before I start to worry? Should I feel them moving inside of her?

Are you positive she is in labor?

If she seems to be struggling or in pain, call a vet right away, otherwise I would not worry too much. She may find a hiding place to nest and give birth, so watch her carefully.

If you see a lot of blood or signs of pain and struggling, you definitely should call a vet right then, but if she is not having trouble I would not worry much.

Feline How-To Manual: Pregnancy and Delivery ~ Pawprints and Purrs, Inc. (http://www.sniksnak.com/cathealth/howto15.html) I hope this answers some of your questions. I have no experience in that area. There is also a section about kitten care, if you click on cat health located at the top of the page and then look to the right column. Good luck and please consider spaying her as she will come into heat and have around 3 litters per year. If you visit the pounds, shelters and prvate rescues you will see that the world is overflowing with cats /kittens in need of homes. Also there are many health issues that can be avoided with spaying/neutering.

My cat when she was in labor acted totally normal all day long and into the evening, then she went upstairs and hid in a closet and had her babies on the floor in there, she was totally silent and didn't leave much mess at all. If you hear her crying, it might be a sign of trouble, as in nature mother cats are fairly silent while birthing so they don't attract anything that may harm her newborn babies.
