Why is my pregnant mouse bleeding but not giving birth yet?

Your friend’s mice were probably just startled for some reason when you approached them today. I would recommend that you continue to engage and interact with them regularly to help gain their trust. The mice are in a relatively new environment and are probably very prone to stress. I would also recommend separating the pregnant mouse from the other two mice. Her pregnancy and birth can be very stressful and so anything you can do to help relieve her anxieties/stress would be good for her. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. It is hard to know if she is fat or pregnant. If she has been in with a male in the past month she very well could be pregnant. The other female mouse might eat the babies, so I would separate the mice if she does have babies. Best of luck with your little ones!

Thanks for reaching out about Peanut and including photos. If she has dead fetuses in the uterus, there is nothing you can do at home and a veterinary visit is needed ASAP. Try to encourage her to accept food and water via a syringe. Provide a quiet and warm environment, separated from other mice. Good luck.

It sounds like this could be a prolapse. I suggest you get her to a vet for an exam. If you want to post again with some photos we may be able to help you better. The photo you tried to post did not show up.

Cocoa does look pregnant. Gestation is about 3 weeks. She built her nest where she feels most comfortable and secure. This is no cause for concern. Try not to disturb it and when the pups (baby mice) come, do not disturb the nest for the first two weeks. You'll need to keep Ghost separate, because Cocoa can mate again within days of delivery. The pups will wean around 3-4 weeks and should be separated into male and female groups shortly after. They can breed as early as 6 weeks of age.

The only way to be sure Lucy has a retained fetus is by doing an x-ray. Sometimes a vet can palpate the abdomen and feel a baby inside but this can be tricky for even a trained vet. If Lucy truly does have a retained fetus for going on 10 days she would likely be very ill. She probably would have an infection in her uterus and would be very lethargic and not eating. If Lucy is acting completely normal she probably does not have a retained fetus. If Lucy is showing any of these symptoms she will need to visit your vet and a surgery may need to be performed to remove the retained fetus.

Thank you for using Petco Pet Education Center, formerly Petcoach! You are correct in planning for the arrival of the pups. I recommend separating the male as soon as you are sure that the female is pregnant, because females can get pregnant again very shortly after giving birth. It is important to keep the pups quiet and calm, to prevent the mother from eating them when stressed. You should also not touch the pups until they are about 14 days old. There are several types of nesting material available in pet stores, or you could use pieces of paperCut up into small strips. The pups should be separated from their mother when they are about 14 to 21 days old. At this point they should be able to eat normal adult mouse food. I hope this helps and I’m happy to answer any additional questions you may have!
