I have used this product multiple times.  In fact, I purchased four tubs of the gold and silver luster dust (2 each) five years ago and I am JUST NOW running out!  I use this stuff to gild all sorts of things for Renaissance themed banquets - including gilding an entire roast duck and then, using vodka, painting filigree designs onto it!  The clients thought it was prop food it looked so beautiful.  I can't recommend this stuff enough!

I gave it 3 stars because of the quality ingredients. But if neither of my cats will eat it, what's the use? We tried weaning them to this food from the junk we've been feeding them by mixing and slowly increasing the amount of Felidae, or by getting them real hungry first, all to no avail. The only way they'll eat it is if we cover it with drippings from fish we cook for ourselves, or from cans of sardines.  More than anything, I think the mushy pate type texture bothers them more that the taste, because it smells pretty good to me.
