I was expecting a lot worse. Its not the best but its far from the worst tiger enclosure in AZA zoo. I wish it was another subspecies though. Amur's in Texas doesn't sit well with me.
No it's not too bad area wise for the Tigers, the problem lies here in the climate. It was blisteringly hot the day I went and totally unsuitable for Siberians. BTW ISIS lists them as having Indochinese Tigers as well. Real Indos and not Malayans.
