Been twice in the last 5 years and its got way much better.
the layout and the range of animals. So much more than the original birds and a bit of wildlife.
Overall well worth the money and a great experience to see such animals who seem overal well looked after.
As for the comment on poor feeding of the tigers/lions etc. we saw then get feed!!! And no problems there. If you thought i was hot go earlier or alter as we did.
