Lemming

Lemmings weigh from 30 to 112 g (1.1 to 4.0 oz) and are about 7 to 15 cm (2.8 to 5.9 in) long. They generally have long, soft fur, and very short tails. They are herbivorous, feeding mostly on leaves and shoots, grasses, and sedges in particular, but also on roots and bulbs. At times, they will eat grubs and larva. Like other rodents, their incisors grow continuously, allowing them to exist on much tougher forage than would normally be possible.
