Maus

Field mice bear an average litter of three to five babies – but can be as high as 13.  After three weeks of gestation a female mouse is ready to breed again immediately after birth.

With ample food supplies breeding will continue.  Under perfect conditions a single breeding pair could conceivably crank out about 500 mice in approximately 5 months.  The life expectancy of wild mice is only a couple of months.

Field mice are blind, deaf and bald at birth but mature within about 3 weeks.  The females are ready to breed at 4 to 6 weeks.  Field mice are of course found in fields and care also found in barns, sheds and homes.

I found these babies on the driveway.

I have no clue how they got there.  All I know is that there might be hundreds fewer mice as a consequence.

And we generally have more mice than we need...
