I've never heard of them before.These sound interesting. My Storm has always had some dandruff but now that he's been eating his Royal Canin Urinary S/O wet food his coat is doing much better. It has a lot of moisture in it so I guess it's doing it's thing. I've also noticed that all of my other cats feel a lot softer now too even though most of them only eat the dry form of this.

I hope that your cats skin will improve with this.
