These grottos look like horrible exhibits. That has to be painful for the bears to stand, sit, and lay on.
I always knew Cincinnati had bad bear exhibits, but I didn't know they were that bad!
@arctic wolf- I don't see grassy gorilla exhibits with no climbing structures becoming 'the norm'. When I went to find another example of a bare gorilla enclosure, the only one I could find with absolutely no climbing structures was Topeka's (which based on the photo is argueably the worst ever). Certainly I've seen gorilla enclosures with little climbing structures but nothing as bad of Topeka's (especially Topeka's) and Philadelphia's.
