I had a normal, short haired cat that lived 21 years. Three times in her life, her winter coat came in like a chinchilla. Those 3 years only, we had snow and ice on the ground for several days. Otherwise, we got, at most, a light dusting of snow rarely and a few nights of freeze, while she got a slightly thicker coat. I’ve never seen such a drastic change in any other pet!
