We've had the female and male mouse in together for the past month. Over a month, really. And still no babies. All they do is fight over who gets to eat the peanut. When we got them, the age of the female was unknown and the male was bought from Petsmart. His age is also unknown, but they said he had been there for about two months.

Should we give up on these two or should we keep them together and see what happens?

In case they don't produce any offspring, we have a female who is 10 weeks old and a male mouse who is around 5-6 weeks old. I will be asking about his appearance in another post since he looks a bit odd.
