It prefers to burrow in the sides of grassy mountains, and lives in small societies, burrowing deep into the stony ground; several side-passages serve as a means of ingress and egress into the principal chamber.
Early in the morning as soon as the sun is up, and the air a little warmed, it issues out of its habitation and scampers about feeding on the grass, not returning to its burrows unless disturbed, till about ten o'clock, where it remains till two or three in the afternoon, when it again comes out and plays and feeds till sunset.
