It is not Azizi. She already had a baby rhino this year. It is not the lioness. It is not Ember. I doubt if Victoria was AIed she would be due already. So it is not her. Snowflake has not been here long enough. It is not Zakula. It is probably not Ibo. It is not Candy because she still has her baby.
Sox the giraffe has been approved. Perhaps the younger female tiger. Maybe a sea lion. Maybe Leela the siamang, but the zoo is likely to swap pairs in the new breeding plan. The female red panda is also a candidate.
Just some thoughts.
Warty pigs are a possibility too.
