MADRID (Reuters) - Walking pet lions around the neighbourhood can be risky. Two lions, a male and female, became agitated while being walked in the southern Spanish town of Ceuta early on Tuesday and mauled four women passersby, injuring three of them critically, a local official said. An government statement said the lions, which are one and two years old respectively, were being kept illegally in dog houses without proper documentation and would be taken to separate zoos. It did not say what would happen to the unidentified man who was walking them.
