Chapter 609 - Bunnies

Bunnies are way too good at reproducing. The females can already breed when they're just 5 to 6 months old. Their gestation period (pregnancy) only lasts a month and they can even give birth to duodecaplets (12 babies at once). After giving birth, they just need a few days before they can be i.m.p.r.e.g.n.a.t.ed again.

That basically explains why carnivores don't run out of food.
