It is funny that you should post an update today, as I have been thinking of posting. Our sweet nearly 11 old Persian, Raven, has not had an outbreak of the crusting, she gets it around her eyes, side of mouth, and her jaw, since I started to add the following to her food(Raven is a kidney kitty that eats Hills k/d wet food(she has no teeth, but can gum the dry food). OK, about a half tsp of Dream Coat, Anitra's Vita-Mineral Mix(both are made by Halo-www.halopets.com), for Cats Nu-Pet Feline Granular(www.arknaturals.com)and lecithin granules. This has to be increased s-l-o-w-l-y in about 4 tsps of water(since Raven eats wet food the whole thing can be mixed together!! Besides the black coffee ground crusts being gone, he coat is so fluffy and shiny!!! Please let me know if this helps. Raven has NEVER been treated with antibiotics or steriods for the crusting, but what a HUGE surprise to see that this worked!!! GOOD LUCK!!! Sandra
