I think these win not only on cute but on awesome naming: meet the Dik Dik.
They're named after the sound they make when startled, which I would guess is really just their way of saying "you're a total jerk" to whatever disturbs them. They live in open plains frolicking amongst other adorable grass-eaters such as giraffes, zebras, and other antelopes.
Weighing in at only 6 kg max (roughly 13 lbs) and standing a mere foot or so tall, they're just a tiny little package of almost unreal anime-style cute. Like us (or at least the best of us), they form life-long monogomous relationships. Can you imagine a baby Dik Dik?
Yeah, they're even cuter.
