Oh my goodness, how sad and cruel....
I agree Jeanie - zoos? Yuck.
I remember years ago, when my children were little, taking them to a zoo in Eindhoven in Germany. There was a HUGE gorilla there, stuck in a cage so small that it practically fitted it - she could put her arms through the bars....
When we got back to England, I got in touch with Zoowatch (it's run by the people who starred in Born Free the movie, about Elsa the lioness?) and we managed to get that gorilla removed to a free-er, happier environment.
I think we all should keep an eye on these little Yorkies....
