I was about to throw in the towel with my rat breeding colony, when last week my two females started to look just a bit fatter than usual. Then, yesterday I see that both of them had their babies!! The litters were a bit small (only 9 and 6) but the 2 females are a bit geriatric; I may retire them and start with 2 new girls.
To boot, my breeder mouse female is pregnant too! she looks like shes about to burst. Her babies will be traded off to my local pet store for crickets or something else I'll need.
Yay!
