KREFELD (TG)First he was homesick, but Kidogo, a gorilla in Krefeld zoo in Germany, now appears to be enjoying himself with a walk across a tightrope similar to daredevil Nik Wallenda. The 12-year-old silverback moved to Germany from Denmark’s Givskud Zoo at the end of March. After he initially suffered extreme homesickness, he has now discovered he is somewhat of an artiste. This year, Krefeld zoo celebrates its 75 anniversary.
