Our cat got injured recently when we were out of town and spent a few days at the vets office. He had to have medication and had several areas shaved on his body. He is a black male approx. 5 years old. The hair is growing back in gray. I have never seen hair color change on a cat. Is this normal or should we be concerned?
Yes, this is possible. There is not to much you can do about it. vetcare
