1. Touni is a normal breeding female and likely to have another baby(if allowed) after the usual birth interval.
2. Kera is unlikely to ever breed again- being desocialised it was young male Komale who fathered her only offspring, not Jock. She doesn't mate with him.
3. As she isn't rearing Hasani herself, Kala could easily produce another infant (if allowed) 'behind the scenes' while they are still living at the closed zoo.
4. The two young zooborn females will be potential breeders elsewhere in the future possibly- unless the zoo replaced Jock in which case they could stay but I don't think they would do that.
