It looks decent though it's fairly expensive at the MSRP on their site! If you want to use freeze-dried raw food as a topper, I think Northwest Naturals, Primal, or Purpose would likely come out cheaper, though the bags would be larger. We feed raw food as meals and use bits as toppers, too.
I use Dr. Elsey's Clean Protein (chicken), which is very low-carb (no fillers) though it isn't raw, for similar purposes: a topper on canned food and a small nighttime treat for a cat who barfs bile if she gets too hungry. Dr. E's is much cheaper than the raw foods and they sent me a couple sample packets.
