Well again, the big difference with zoo medicine compared to I think, domestic animal medicine is that you’re usually always anesthetizing the animal. You’re immobilizing the animal, I guess. Difference being immobilizing is keeping it so that you could do something to it. Anesthetizing means that it’s not gonna have any feeling either, it’s not going to feel it, as opposed to an immobilization, well they can’t do anything, but they still feel it. And so, you know again, anesthetics or these various immobilizing drugs hadn’t been used on all species, so figuring out the correct dosage was important. But then there’s, one of the bigger ones was a product called, CI-744 was the experimental name. Parke-Davis was the company at that time that had that available. And so I was able to get the product, it was not marketed yet at that time.
