As I understand it, fever coat as such is seen on small kittens, it wears off by itself in a few months.I don't know if anyone is still watching this thread but I wondered if you ever found out what the deal was with the long white hairs? Did your cat outgrow them, so to speak? My cat, Emmett, is 10-11 years old and I only just noticed similar hairs on him in the last week or two. They are on his sides, low by his belly; on the outside of his legs; and the outside edges of his neck to just below his cheeks. I don't know what they are or where they came from. I wasn't worried until I saw something mentioned on here called "fever coat". What is that? Should I be worried? He has been sick recently so is that it? If you have any ideas let me know! Thanks!
At your age, its something other, I think. Possibly beginning of old age, when the fur tends to be grayish. usually mostly around the face.
Yours? I dunno, but if you do have access to a good vet, I would mention it to her.
