We were at Edinburgh Zoo at Easter and I was so disappointed by the whole thing. I totally understand why the Zoo has pursued a policy of thinning out its collection and providing good environments for a few animals rather than poor conditions for loads of animals but basically, there's not much left apart from penguins, chimps and pandas. We were also at Chester Zoo this summer and that was amazing, twice as good as Edinburgh.
They must be DESPERATE for a cub - they're paying $1million a year for these blasted things which won't breed. The zoo saw a surge in visitor numbers when the pandas arrived and this has now tailed off, a cub might help them get numbers up again.
Longer term though I think they need to accept that Corstorphine Hill is a really crap location for a zoo and they either need to close, or move somewhere with loads of space and start again.
