I actually did see all 6 cats, and there was a zookeeper there that pointed out that there were 3 in each of the exhibits. If I'm not mistaken they are all females with zero males at the park. Is that correct? Looking at this photo I have to say that for me the tiger enclosures at DAK were perhaps the weakest animal habitats in the entire park.
This does not look like an exhibit where you would see a pacing tiger. I mean sure, its not the greatest tiger exhibit, but its not an exhibit where you would say "poor tigers". That would be something you would say at like a grotto exhibit with little substrate.
