That is very sad news to hear. I was prepared for this moment seeing how Sabi was at an elderly age, and has outlived his littermates. It's a shame neither him or Marjan never had any offspring to continue their bloodline. May Prince Sabi rest in peace with his brother King Marjan, mother Queen Millie, father King Kimba and the rest of their ancestors.
Same here. He certainly reached an impressive age! Some of his ancestors/lineage at Paradise Valley Springs have reacted similar ages. His maternal uncle Max lived until 19; and his maternal grandmother Honey and maternal great aunt Suzie reached 22 and 23 years respectively.
The Paradise Park descendants in ZAA zoos haven’t been recommended for further breeding, which may explains Sabi not breeding in turn.
