Were the same colors banded on one strand of hair? In other words, two different colors on the same strand? That wouldn't be unusual in many breeds of cats or dogs, and other animals--even horses. It could be from a parka hood, that had animal hair around it. I would imagine they know the type of animal, and if it was a live animal, or processed fur. How many hairs? It would appear that JBR grabbed at someone---but was it something he had on---or hairs transferred from an animal?
