The right-hand half had a bit more climbing that doesn't show in either photo but no, it wasn't a great enclosure for them. I saw two on my first visit (when I took the skunk photo) and one on this visit.
Barcelona in general is what I would probably describe as a 'well-meaning' zoo - very few of the exhibits are really good, a small number dire, most OK-ish. There've been quite a lot of changes since my last visit though, I believe.
