What if, when you chase a female cub, it automatically grows into an adult and can be found in explore? Or, if it's male, it turns female and grows up.
This currently doesn't happen, but what if it did? It'd give some new players chances to get beautiful NCL, and some people pretty gals with clean lineage.

If you disagree at all, please comment below why! I personally don't see any flaws, because after a period of time, if a lioness isn't claimed, it gets deleted.
