My black kitty has the most gorgeous fur, but of course it's black so his dandruff shows. He didn't used to be so flaky. (ha,ha!) But he doesn't hardly ever wash himself, so I can't trust him to take care of it. Is there a shampoo or something I could use on him to get rid of those icky flakes? He's such a pretty boy, and the dandruff is making him so much less pretty!! He also has one leaky eye, but I think that's probably just allergies.
