So we made it as easy and as safe as possible to handle the animals if we had to. We also trained the animals to react to certain things. Feed them in one area, and then if we had to we could put a crate in that area and feed them in there. And capture them so that there wasn’t a lot of grief, and a lot of discomfort for the animal. So we tried to examine all those animals all those exhibits, build all those exhibits so that they would work well. We did build one quarantine area for gorillas and big cats. And we had a kind of a standard policy when the engineer said that this exhibit will hold an elephant or the weight of an elephant. We always said double it, make it twice as strong.
