I agree, the staff comments try to remain calm and pretend everything was ok and noone got hurt.
I was there last year and saw the liger and a tiger cub (the cub isn't mentioned in the article, so they have at least 1 more cat).
There are some things they do there that really annoy me (for example, taking your picture with the tiger cub or a gibbon). They used to have orangutans in a horrible little cage but I didn't see it last year so at least they're gone but there are many cages there that are probably not up to AZA standards or if they are they are the barest minimum.
