Whilst I agree that animals need privacy, the purpose of a Zoo is supposed to be to conserve and educate, unfortunatley Dudley falls short in both of those respects in my opinion, and always has done. There is no excuse for the level of delapidation and run down areas in the Zoo, where animals are still kept.
Of course animals in the wild dont have cut grass Adrian

but its the fastest way to drop numbers visiting if animals cant be seen. As a photographer, its a waste of time, so what the none "togs" may think, but a huge proportion of Zoo visitors, especially out of season are photographers, if they cant achieve even a reasonable shot, the place will be avoided, not good news for the Zoo concerned then is it? Funds will drop rapidly.
I have seen this in all Zoos Ive been to, which have you seen this as being not possible? The Giraffes yesterday couldnt get inside could they? Nor could the male Snow Leopard get outside, meaning the female couldnt get inside.
It doesnt matter how many animals are in an enclosure, its the quality of life and welfare that is paramount. its ok saying there is only one, but what about the welfare of that one? Does it not matter that its a single? The Bear and Tiger pits at Dudley ARE the pits!
Of course its the Zoos fault, they are constantly accepting new animals they cannot cater for, they should refuse untill they have the proper environment for them to live in.
Then IMO, those poor creatures should be removed and resited in a better place where they can display the correct behaviour, another park/Zoo.
Thats a bit rude, and uncalled for too. The pools stink and I have NOT smelled anything like it anywhere else, I suggest a trip to Whipsnade, or Chester for starters, and perhaps Cotswold Wild animal Park, I guarantee you they dont smell like the pools at Dudley.
I can see that you are very "pro" Dudley, whereas I am very "pro" animal welfare in Zoos, we differ on this.
