While I agree and it's probably just loose fur, my boy Kipper has had a spot on his head where the fur has been longer ever since he was born (and he's now 6). It's so strange! I have even pulled it out on multiple occasions, and it grows back in, lol. Still don't know why he has it, but he's my little unicorn! I guess this could be the same thing? It is much longer fur than Kipper's though.
