I have found that figure-H harnesses rub the fur off an area between the shoulder blades if worn for long periods. As a result, I have made my own harness out of leather...specifically to prevent rubbing. I understand that it may have not actually rubbed the furr off, but you can see where the figure-H harness crosses between the shoulder blades...and it does not look comfortable. How is that for a reason for a preference. Just my two cents worth. Mike and the ferret duet, Krysta and Maple. [Posted in FML issue 2146]
