I'm just starting my cats on raw and having the same problem. I've read to slice up tiny pieces of raw and hide them in wet food. Two of my four cats eat around them so far. Very gradually you increase the amount of raw and decrease the amount of canned. I've also read to douse the raw in tuna or sardine juice or a bit of salmon oil, or to crush up some freeze dried chicken treats and sprinkle them on the raw. You could sprinkle on grated cheese or a bit of catnip.... None of that works for me so far, but it might for you! I'm just going to keep hiding it in their wet food and try to find a flavor of wet that they can't pass up in hopes they'll eat all of it, raw included.
