Have to agree entirely with this post!
Tiger Territory really is an excellent exhibit, but I find it hard to believe it cost 3.5 million. I too was sceptical about spending this amount on a current species, relatively common in UK zoos.
I can believe that. London do seem in the business of creating very expensive enclosures, in the past with fancy architecture too, irrespective of whether they are particularly suitable for the inmates(I am not saying the new Tiger area isn't).
'Gorilla Kingdom' cost more than that I believe, yet five years or so on, they still have just about the poorest/smallest/non-functioning group of Gorillas in Europe, certainly for a zoo of this size. Obvously these ongoing troubles are not connected with the enclosure but it shows lavish enclosures and expenditure don't always go hand in hand with successful results.
