So it’s made of shit, right? And shit is an animal product. But barring a night of drinking or a particularly aggressive burrito, shitting does not harm the shitter; it’s beneficial and required. Also the animals in question can and do consent, does that make it vegan?
No, it is not vegan. Much like for example cultured meat, real animals had to be harmed to create the original specimen that is being cloned. For the purposes of veganism, animals are assumed to lack the capacity to consent to exploitation, in much the same way that children are assumed to lack the capacity to consent to various things.
