In May of 2009, my long-haired black cat (with 3 legs) almost died of a urinary tract blockage. He was in severe stress for 3 days until he had a PU surgery that basically made him a girl.
Over the last few months as his hair continues to grow back in, it is coming in white/silver. In addition, his entire body of hair is turning a white/silver color within the black hair. He now looks peppered. He is only 3.
Why did this happen? If I shave him will it grow back black? I normally shave him in the summer anyways but didn't this year due to his illness.
Are there vitamins I should give him to help? It's no longer soft hair. It's kind of coarse.
