Don't look too surprised, giant kitty — you're live on candid camera trap! Zoologists and ecologists these days use "camera traps," or motion-activated cameras hidden in natural habitats, to observe wildlife without harming them. The resulting pictures are often heartbreakingly gorgeous, occasionally goofy, and reveal animals we never knew existed.
