A SAFARI guide thought he was seeing things when he spotted a leopard acting like a meerkat. The big cat in question had been carefully stalking a warthog when its prey disappeared into some particularly long grass. In order to keeps its dinner in sight, every few minutes the leopard would balance expertly on its hind legs - doing an excellent meerkat impersonation - and peer over the grass. The bizarre spectacle was caught on camera by 27-year-old Letsogile Kamogelo at Savuti Camp in the Linyanti Game Reserve, Botswana. Mr Kamogelo, who works as a safari guide, said he had never heard of a leopard behaving in such a way. He explained: This leopard had spotted a warthog from a distance and stalked it for almost an hour. WO
