At the Alipore Zoo in India, a female tigon named Rudrani, born in 1971, was successfully mated to an Asiatic Lion named Debabrata. The rare, second generation hybrid was called a litigon. Rudhrani produced seven litigons. Some of these reached impressive sizes—a litigon named Cubanacan (died 1991) was estimated to weigh least 362 kilograms (798 lb), stood 1.32 metres (4 ft 4 in) at the shoulder, and was 3.5 metres (11 ft) in total length.
