My gray cat's fur is turning brown. Is it normal or a diet issue?

My cat Mary has been getting some fur discoloration, especially on her right shoulder. She is a gray cat, but her fur, especially in that area is turning brown. What could be the cause of this? Is a nutrition problem? Should I be giving her supliments of some kind?

Thanks for using Petco Pet Education Center, formerly Petcoach! This is likely just a normal coloration change and nothing to worry about. There can be changes in the coat coloration throughout their lifetime. I do not think there is something you need to do at this time. Best of luck!
