The other day I noticed Jubilee's coat hairs were sticking up a little tiny bit. Not just a few hairs in random places but in big patches. It wasn't really that noticeable, but when I brushed her, the hairs weren't lying completely flat. Then, yesterday when I brushed her, they WERE lying flat. I don't know if this is even important even to bring up as an issue, but I was just wondering what it could be. I was always told that hairs sticking up isn't a good sign. Was it just dirt or because of heat or sweat?
