Well basically hippo’s an aquatic animal. So you have the problem of them if they go in water, or if you dart ’em with a drug that causes ’em not to breathe, they drowned. So some of the early work where they used M99, or some of the narcotics, they just went into the pool after they were darted and drowned. The other thing is they’ve got a tremendous thick layer of fat in getting the drugs internally. Another reason is they’re difficult to get any kind of monitoring equipment on ’em, like your pulse oximetry and access to veins, and blood vessels are extremely difficult in hippos, and they’re tremendously dangerous animal if you don’t get it just right. So other than that, they’re fine to work with. You talked about Front Royal, and going there, the Conservation Center, there was talk at one time of closing that facility.
