Dean and Prayeri Harrison, the owners of Out of Africa asked me to play the didgeridoo at a habitat where two tiger mates, Passage and Saginaw, were fighting.  This habitat was also shared by Saja (a female spotted leopard) and Eclipse (a male black leopard) who are also mates.  Within a minute of sounding the didgeridoo the fight stopped and one of the tigers and the two leopards came close to bathe in the sound.  In this scene Saginaw, the male tiger, lays down to enjoy with Eclipse the black leopard sitting nearby.
