Another drug was succinylcholine, which is a paralytic drug, and it’s even used today in human and animal medicine to stop respiration ’cause it paralyzes the muscles of the chest. And a certain dosage would be used by the anesthesiologist along with other drugs. But it was not unusual to, for example, knock down an animal with one of these tranquilizing darts and you were in there with the animal, but you weren’t certain if it’s gonna sleep for two minutes or an hour. And there were times that we’d be in with some of these big critters, and they started moving around before we expected them to, and created some pretty scary situations. So I would say that our early years in determining the dosages for different animals was the challenge. And fortunately enough zoo wildlife researchers out in the field and the zoo vets at the various zoos started sharing all their knowledge and putting together basic dosages, so you knew that if you were gonna shoot a 20 pound monkey, you used a certain kind of drug, ketamine, was one of the common ones at that time that was safe. You knew if you were gonna stop a rhino out in the bush in Africa or in the pennant one of the zoos, a certain amount of a drug called M99, which was kind of like a morphine concentrate. And it just took 5 to 10 milligrams of M99 to put down 1,000 or 2,000 pound animal.
