A mom and pop place about an hour away from me. They are doing the doo but nothing is happening. All the mice were in the same cage(both males and females) and I asked how long they were with each other. I was told about a month. and there are still no babies. I asked where They got them from and they "couldnt disclose that info". Im thinking some lab. They are all albino. Every store near me (besides Petsmart) has only albino mice. And they all have the males and females in the same cage with no sign of any babies. I asked this store i just bought from about that as well and they told me they havent had any give birth. Rats in all the stores are the same. same male/females in the same cage, no babies and all are albino.
