Answer:
The correct answer to the question lies in the fact that vegetarians, and most vegan trends, do not eat any product in which animal meat, produce that is meant to feed young animals (like milk), and products in which animal labor has been used, can be consumed.
Because all these are principles and values on which the vegan and vegetarian lifestyles are based, then the moral question becomes if the product to be consumed may have any of these conditions in it, or not. From here, will they be able to tell if eating something specific is morally right or not. And because there are so many different vegetarian and vegan ideologies that vary on minute details, the moral question really comes down to if the consumption of such an item violates one of their principles.
Since essentially an animal cracker is made out of parts of animals, like bone remains, since the vegan principle is not to consume anything that comes from an animal´s body, then, it would not be morally right to consume that cracker. However, if the cracker is a simple one, with no animal body parts involved, and it is simple wheat, or another grain, then it would be morally right.
