I have been on a behind the scenes tour there. They have a pretty enormous amount of space. As with so many creatures in zoos now, the care is about keeping stress levels down so they don't feel they're constantly being watched by people... which means the general public cannot see the entire enclosure indoors or out
@JoesMum Can you go into a bit more detail, is the tour still possible today? Any chance of a link to it? also how much space did they actually have behind the scenes, even approximately would be great? Thanks!
