Thread: Change in fur colour

When Wicca arrived, she was clearly a black smoke - she was jet black, except for the silver/grey/White around ruff, belly and under chin. You could part the fur anywhere and see it was grey at the root, too. But over the last couple of weeks, I've noticed a red/brown tinge to her coat across her shoulder blades and the top of her back. When I first spotted it, I kind of thought it was caused by poor lighting, but now it's very noticable. Just wondering if it's common, whether it's seasonal now the warmer weather's here, or if I should be concerned? She's her usual crazy self in every way and no change in her appetite. Any thoughts?
