These enclosures are very nice - and I'm not surprised to find them more to your liking, snowleopard! It's unfortunate that one female tiger will not leave the entrance of the dens - seems to have some form of feline agoraphobia - even the keepers have only seen her move out into the exhibit on rare occasions.
@Maguari: that is an interesting comment about the female tiger, and hopefully one day she abandons the den in favour of what appears to be a rather naturalistic exhibit. Also, you know me well on ZooChat now! Any animal enclosure that is green, lush, spacious, realistic, etc...I love! Maybe it is from visiting the Woodland Park Zoo too often, as I happen to live 5 hours (roundtrip) from that top-notch establishment where it rains all the time and the zoo is as green as any I've ever seen.
