It's been 8 years so I can't remember exactly but I think this photo shows only half of it. I also think it dates since the LA Zoo opened on its present side in 1966, which would explain, but Blackduiker or Mstickmanp would be able to tell us more.
This photo shows a bit more than half of the enclosure, but the exhibit no longer looks this green. All the grass was mainly killed by 2 different litters, the two huge palm trees were cut down, and the smaller palm trees are way bigger.
Well I guess if the tiger have managed to produce two litters then the enclosure is probably ok. I quite like the look it has to it although maybe abit more cover at the back would be good.
