So I mean, in, for example, I remember we had a, a particularly ferocious muskox bull. We had a little group of muskox and, and one, I remember one day when the keepers came running to me to say, the muskox bull has broken out through the roof of his shed. So I went down to the muskox exhibit and there was, and this was a pretty simple sort of cow shed really with a, with a couple of stalls and the muskox head and shoulders were sticking out through, through the roof with this animal sort of bellowing away. I mean, he wasn’t actually gonna be able to get out like that. But clearly something had to be done. Nobody, there’s no literature. I don’t think anybody had ever immobilized the muskox before. You know, this is 19 69, 19 70.
