The Arctic hare employs the specialized digestive system of recycling that is common to all members of the hare and rabbit families. This system is called reingestion or refection. It allows better utilization of nutrients.

The first stage in the digestion process takes place in the usual manner in the hare's digestive system. This produces a soft fecal pellet of partially digested plant material. The hare eats this soft pellet directly from the anus. The end result the second time around is a round, hard pellet.

Reingestion of the soft fecal pellets happens during rest periods. The hard round pellets are passed while the hare is moving and feeding.
