You might try talking with Kelly - she isn't online much now due to living with her parents and work but if you have her number, give her a call sometime. Her Micah has the feline equivalent of IBD or Chron's (? not sure which) and she feeds him a raw diet when he has flare ups. He loves it and it reallllly helps him a lot. He is the only cat of her's that gets it and I think only when he has flare ups.
