A scary video has emerged of a lion pawing the windowpane of its enclosure apparently to catch a toddler standing near by. <br /><br />The footage, shot at Oregon Zoo, USA in 2016, captures the moment the lion leaps at the young girl who is facing the other way. <br /><br />Visitors can be heard screaming with surprise as they witness the "attack".<br /><br />According to the girl's mother, zoo staff members told her her daughter's outfit made her look like a piglet which might have triggered the lion's behaviour.
