Mice help

post #1 of 13
Thread Starter 
I have had 3 female mice and 1 male together for some time now!
in theory they should be pregnant (13 days with male in with them),
but we have done this before and no babies arrived....
sooo do i leave the male in there till the 20th day (gestation is 21)
or do i take him out now?

Were the mice ever pregnant? Could they have given birth and then the male or female eaten them right away.

Are you SURE you have a male in there with them? Seriously mice breed like crazy - you have some strange mice if they are not pregnant

i have found sometimes, male mice get comfortable with their company and they dont breed, i found getting a new male and swapping them round some times helps

How old are the mice?
I had a couple of males that seemed infertile.They were kept with females for long time and the girls never ever got pregnant.

Yeah, maybe he's 'firing blanks'? I'd take him out now just in case. If they're not pregnant yet then they probably won't become so after just a few extra days...
Good luck

Mice, just like rats, have a gestation period of an average 30 days.

Be sure the male is out of the cage when the females give birth, as the male can get the females pregnant seconds after birth. Two litters in a row is extremely hard on animals.

Most of the time, females do not show that they are pregnant until a week or even a few days before they give birth.

Thanks it was more a worry that the male wasnt "working" so too say
