Bear pair

It'll be a while before this adorable cub is a fuzzy juggernaut like his mom, but until then, she'll stand guard. Female brown bears stick with their cubs for well over two years, taking on sole cub-rearing duties as males make an early exit. Mama bears are aggressive protectors of their litters—so as tempting as it is, don't try to play with this cute and curious-looking cub or you're sure to see some claws come out.
