i don't agree with the usage of any animal products simply for the utility of tone. This "polymerised animal protein" business sounds fishy to me. I think this is inherently wrong unless i know more about how they are made, they don't give you any details on the website about how that poly cr@p is made which i think refutes their point of "guilt-free" ; they are only giving you the option to be guilt free because they don't even tell you where this shite comes from. $% THAT!
Bone nut is one thing, but this seems to be something entirely different.
