Meet Lulu and Roscoe, the Milwaukee County Zoo's newest Fennec Fox kits. Born January 27th, the cubs recently made their public debut accompanied by mom, Daisy, and father, Duke. Fennec foxes' oversized ears act like natural air conditioners, radiating heat away from their bodies and cooling their blood in the light desert breeze. Their ears also help detect tasty prey at night, including small insects scurrying nearly-silently atop the sand.

Keepers describe the kits as very playful, enjoying their toys and rough-housing with each other.
