Well she's by herself now and I'm wondering if she's ill, I cleaned cages today and this mouse sat in the corner breathing heavy the whole time, when holding her she acts normal but we shall see. They have been fed a weird diet lately because I was waiting on food to come in, it got in last night so it's possible she pigged out. I'll know in a few days, either she'll have babies or she'll die. I'm going to keep an eye on the bin and make sure none of the others show up pregnant, I would think if it were a missexed male that the older females would be PG as well. Who knows.
