Who knows but the Columbus Zoo and Aquarium recently posted video of its 5-week-old polar bear cub, sleeping not-so-silently.

The baby weighs about 4 pounds and is 16 inches long. She just started opening her eyes and has been trying to stand up on all four paws, the zoo posted to its Facebook page.

She's being taken care of 24/7 by zoo staff after the mother stopped caring for her.

She does not have a name, yet.
