Fossa at Bioparc Valencia, 28/05/11

How big is the enclosure here? How much climbing space do the animals possess?

Here's a view of the exhibit with an animal for scale: http://www.zoochat.com/180/fossa-island-bioparc-valencia-28-05-a-220294/

The clump of trees/bushes in the centre is all accessible to the fossas - I love this photo by panpaniscus: http://www.zoochat.com/180/fossa-male-looking-birds-66044/

I seem to recall people saying it was too small - I actually think it's not too bad compared to others I've seen (smaller than Frankfurt's repurposed Clouded Leopard exhibit, but compares well to most others) but like a lot of things at the Bioparc, aesthetics has come first and bit more climbing would be no bad thing.

Yep, see what you mean. Some might say that it's an example of how a desire not to use fencing isn't always to the animals' advantage.
