The collared pika is an almost painfully cute animal. Indigenous to Alaska and parts of Canada, these little guys look like a cross between a tiny rabbit and a hamster. (Indeed, they're related to rabbits and hares.) With a characteristic "eep!" vocalization, they spend much of their time preparing for winter, laying in a "haystack" of vegetation to last them through the colder months.
In this painfully adorable video, we follow the preparations of one collared pika for the winter. Just listen for the "eeps," folks. (First pika footage starts at 0:55.)
