think about it, how many times have you seen/pet a bunny, if something was rabbit fur youd notice by the feel...now how many times have you pet a raccoon?! or a raccoon dog or a badger, or squirrell ect. not all fur feels the same, the raccoon dogs fur feels kind of corse as compared to the usual furs they use and has an almost "fake" feel about it unless your familiar. its the same for many furs, you could have actual racoon fur on a coat and most people would think it was fake due to the rougher texture than typially used in coats ect...
so no, sometimes its not as simple as people teling the difference between real and fake.
ive felt faux furst that feel real and real furs that feel faux...its not as easy and when there not labeled right like in this case...
