you're impatient...

[mr. s]

you're impatient...

...or your rat is impotent

How long have they been together? Sometimes it just takes a few weeks and the females won't really start showing until their 2nd week of pregnancy.

Suzuki, thats exactly what i was thinking...LOL.
Mr.S, that was my second thought but i did not want to jump to conclusions...LOL or maybe not for him...LOL
Jay-Bunny, they have been together since 3/7 but they were alot smaller, i bought them as small rats.

It is very possible that you are just being a little too impatient. However, it is not uncommon to have a male that just doesn't get the job done, or he'll get a few females pregnant here and there, but not nearly as fast & as often as you want.

I haven't really made a scientific study of this, but it seems with my mice, when I let a male grow up with females (like when I want to breed him back to his mother, so I never take him away from her), he takes a while to get started breeding. On the other hand, when he is separated from females for a short while when he is weaned, then put in a colony at around 4 or 5 weeks of age, he'll start breeding right away.

Maybe it would jump-start your male if you separated him from the girls for a while?

the reason your mouse isn't breeding with its own mother is because it is not weaning itself...once you remove it and place it back, it is totally weaned and taking its place in the social order. While it views its mother as mom....it will be focused on potential food, not breeding.

suzuki do you think taking the male out for a week will jump start him?

I wouldn't bother....

patience....

I have an extra 200-400 this week if you really have the need for rats...
