False Pregnancy?

I think my mouse might be going thru a false pregnancy.She hasn't been around a male in weeks and since she is my only mouse at the moment,she cannot be pregnant.

I had a mouse go thru a false pregnancy before and even went into a false labor and died.I didn't have any males at that time either.Misty seems to be getting bigger and not from eating,as she appears to be getting the pear shaped belly.I felt her today and I swore I felt babies...but thats impossible.

She is not sick,is perfectly healthy and acting normal..except for nesting more and stretching alot more.I am going to keep my eye on her tho,and if I see anything slightly wrong,she is going to the vet.

However I am not familar with false pregnancies in mice...I only ever had ONE and that was years ago.So does anyone have info on mouse false pregnancies? It can't be common,as I have owned literally hundreds of mice over the yrs (since 1998) and only had the one go thru it.

Hrmm that's odd...there's a biological response in rodents and other mammals called pseudopregnancy...which occurs when no males are around or females are around a bunch of other females. It evolved to prevent the wasting of eggs...so by prolonging the current menstruation and keeping the egg in and "faking" pregnancy...they can wait till a real male actually does come around to mate. I'm surprised though...your mouse is alone and I was under the impression that pseudopregnancy just involves the egg implanting, developing for a little, then aborting. I dunno...maybe the pseudopregnancy follows all the way through and the mouse has to exhibit all the stages of pregnancy to childbirth? Well, hopefully the false pregnancy ends soon...might be something totally unrelated, but I guess to answer your question, there is such a thing as false pregnancy in mice.

Maybe a wild mouse got in, lmao!! When I was at 118 a mouse that was living in the house was up with the rats, it was funny b/c he knew there was females but they were higher up of of his reach!! I agree with the first post, it probably is a pseudo pregnancy!

Hehe btw, the biological way to stop it, if it is pseudopregnancy, is to get a male mouse nearby...like putting it in another cage and placing the cages next to each other. She'll abort because there are male pheromones about. Before your pets were taken from you, did you have male mice? Maybe the recent absence of those are causing this?

Hasn't that been known to kill and animal if not taken care of right away? I'm not positive but I think I've heard of it before.

Is she in a cage or a tank? I've heard of wild male mice sneaking into cages and getting females pregnant. It's why the mouse breeders I know always say to house mice in bins or tanks.

Fez,yes I did have a male not long ago.

Misty is in a cage with bars because I dislike housing rodents in tanks or bins.I only use bins when I have baby mice.Anyway there is always that possibility that a wild mouse got in,but I am 100% sure we do not have wild mice here!

I checked on her today and her belly is still getting bigger,it looks bigger today then last night.

Like I said I am not familar with fasle pregnancies...however I am starting to wonder if maybe she is pregnant,from either a wild mouse (even tho thats unlikley...we don't have wild mice,but one could of easily got in that I don't know about) and well it has been a couple of weeks since my male was killed,but they were not housed together...but feeling Misty's belly,it feels like there is something in there.

You should watch her very carefully, from the simptoms that you said there is a chance that her swollen belly could be a tumor or an absess. Tumors or absesses usually do not cause the rat any noticable health problems except for the lump. Watch her closely over the next weeks and if the lump dosn't go down you should tak her to the vets.
