That's the Look of Somebunny's Who's Just Heard the Crisper Drawer Open

Caught in the act of trying to escape during an exam!
This little cottontail wasn't actually trying to flee; he was just very curious about his surroundings! Until their flight response kicks in at around 2-3 weeks old, cottontails are more curious than scared. Over time, this guy grew to distrust us and would avoid being touched at all costs—evasive skills that hopefully serve him well now that he's back in the wild!
