Laughter is infectious. The sound of roaring laughter is far
more contagious than any cough, sniffle or sneeze. So if you need a
quick dose of the wild variety, check out the pair of spotted
hyenas at the
Lincoln Park Zoo. Kai and Phika are the first hyenas to live at
the zoo since the 1970s. So why do they call them laughing hyenas
anyway? Because they sound like people laughing their heads off!
You can find Kai and Phika on the northeast side of the zoo in
between the Sun bear and the Andean bear.
