I don't think it makes sense to discuss such details as if all vegans thought alike. There are many differences in thought among them, as in any group of humans.

But I would like to point out that this argument by analogy is flawed: Honey is food for the bees themselves. Taking it away harms the bees by making them work harder for their survival. (Unless you can prove that you only take a surplus that they would never touch.) In contrast, excrement from animals like cows or horses is not used by the animal itself.

As someone else pointed out in this thread, if necessary, many vegans could probably get behind a world were animals were raised for the use of their excrement but nothing else.

Cow shit fertilises the pasture and feeds other creatures/life in the ecosystem ultimately taking its part in creating an environment for the animal. Moreover the seeds the animal disperses will be lost if you abscond with their excretions.

There's a very real way in which a cow, say, feedsback in to the environment. It's less direct than stealing bee vomit, but still a part of the feeding cycle.

The reason I compared them though was primarily that collecting animal faeces of large mammals would probably be an overall negative (cf. bat guano) unless you artificially confined the beasts?

It seemed to me that the necessary interference in the animals natural cycles would be akin to good beekeeping (where an apiarist can prevent hive death, increase food availability, etc.).

Yep, that’s the point, avoid all byproducts.

I’ve seen more products labeled as veganic so it seems doable and they weren’t too much more expensive than organic bread or what have you.
