Murids breed frequently, often producing large litters several times per year.

If only I had thought to bring a litter large enough to carry both of us.

They can produce large litters of 20 or more young, although the average litter size is between eight and ten pups.

Older females tend to give birth to larger litters.

As I remember it, the babies were pupped in fairly large litters.

Such large litters may compensate for a high rate of infant mortality in the harsh environment.

But alas, while there was a large litter they were all of them mongrels.

Achieving reproductive ability early and having large litters provides a biological balance to this.

Pigs breed more quickly than sheep, and produce larger litters.

From my calculations, this species is incapable of producing large litters.
