Despite their mousy appearance, pikas are adorable little lagomorphs in the Ochotonidae family, which means they're actually related to rabbits and hares. They're a common enough sight in the western United States, where they hang out in rocky areas and basically do pika-ish things all day. Maybe you've heard of these guys before, but unless you're a pika expert, you probably don't know this one thing about pikas: Pikas HATE it when you're sad. Pikas will do anything to make you feel better. Here is the irrefutable proof.
