Four-month-old panda cubs show off walking skills

TORONTO (WLS) -- The giant panda cubs at the Toronto Zoo showed off their walking skills on Tuesday.

The cubs, the zoo says, were born on October 13, 2015, and were recently determined to be one male and one female. The sexes of the cubs were determined by DNA profiling, the zoo says, because visual identification is unreliable.

The zoo says the twin cubs are more active and playful every day, often wrestling with one another.
