Thanks for an informative and very well documented set of pictures on these cat enclosures. I find them all far to small and inadequate but it was interesting to see them.
I don't think the cat enclosures are the worst I've ever seen, but so disappointing to see all the effort and money invested in yet more playground activities immediately next to the cat area. This is the only direction their enclosures could have expanded into, and now it's gone.
What I noticed today was that there is literally a single sheet of wire fencing separating the lynx and the pumas. They could literally be inches from each other (i.e. no buffer zone at all) and I don't know how stressful this would be to either cat ? The lynx was hissing at the puma, who didn't seem concerned admittedly, but this does strike me as undesirable.
