That's why I think that they might build a new Tigers area with 3 enclosures (and hopefully bridges between them), which would allow for a breeding pair of Asiatic Lions to take Hutan's enclosure.
I do think that MZ should move all African Lions to WORZ, and thus free up both Indrah's enclosure, and the African Lion enclosure, and those two exhibits could be repurposed, or redeveloped (potentially how
@PaddyRickMFZ described).
I think both Tigers should be on display, and should be in proximity to each other, so that in the future when MZ import a new breeding pair they will have the opportunity to breed them and have both the mother and father in proximity to eachother. Adelaide have theirs set up so that the father can see his cubs when they are on display. This allows for some connection, as wild male tigers, although not care givers, do occassionally interact with their young if they come into contact.
