Snow Cat's coat

Snow Cat is developing more brown places on his coat. This time it is down his spine. Is this common for a less-than-one-year old flame point Siamese? At first I thought it was from him being under my truck -a grease spot. But upon closer inspection it is new fur comming in under the white, on the ridge of his back. Does any one know how long he will continue to develop the reddish brown fur in different places on his coat?

Interesting Wayne! The only Siamese I knew didn't develop brown spots on his fur until after he was two years old. Snow Cat sounds beautiful!
