I was told Andy and Dougy are smoke Persian kitties. I’m no expert of cat coats, but neither kitty is quite as dramatic looking as photos of smoke Persian kitties suggest they should be.
They do, however, have color-shifting coats that show lighter-colored highlights or whole zones that are a pretty light grey in brighter light. In darker light, you still can see grey highlights that help define the shape of Andy, for example, in the photo. I find this effect quite handsome!
One of the lighter zones in the right light is their ruffs. Their tummies also appear to be this light grey in the right light. The photo of Dougy above Andy shows how the right light transforms his ruff into that light grey.
Are they black cats or not? This color-shifting nature of their coats makes me wonder.
