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!

    Most changes in coat color are genetic and tend to happen as pets get older (they can even have premature greying). Infections and endocrine disease can also cause coat changes. You may want to have Panther checked for hypothyroidism to see if that is causing the change in color. I hope this helps.
