As far as I know, some sheep need to be shorn because they were bred to produce more wool. If such a sheep is rescued from a sheep station by an animal sanctuary,
- which is a non-profit organization, and
- where the shearer cares about the sheep,
could this wool be considered vegan?
As they are not allowed to make profit, and as the shearers are animal protectionists, there is no economic pressure to shear in a rushed way (which would harm the sheep).
(Bonus: If yes, does this get done somewhere? Is there "certified vegan" wool?)
