Currently the new enclosure is still getting build, but construction is going fast. I hope it will be finished around July but I can't guarantee it.
@tigris115 Bit of a late reply, but the answer is: impossible. This is a listed monument and is the oldest barrier-free carnivore enclosure still in existence in the Netherlands and likely one of the oldest in the world. So it will be interesting to see what they are allowed to do with it. In Rotterdam they could net over and fill the moat of their listed big cat enclosures, so there might be some possibilities. My preference would still be giant otters
