I'm veggie but eat a lot of vegan stuff and I agree that they do take an interest in anything with dairy produce, milk, butter, cream, cheese, but they really do leave the vegan stuff alone. For example, I use soya milk on my cereal, my husband uses cow's milk. Guess whose cereal bowl they have their faces in, not mine. I accept, though, that for anybody who's a serious carnivore, the cure might be worse than the problem.
