It's no secret that I'm not a fan of kibble for cats, so my opinion (surprise surprise!) is not to go that route. But perhaps your homemade diet could use a bit of tweaking. Although Anitra Frazer is a pioneer of natural cat care, some of her diets are a bit outdated. For instance, you don't need to include the barley or peas, and I'm worried about the taurine content of this diet if you aren't adding any supplements. Also, a better source of calcium would be to either use real bones rather than bone meal, or else use calcium carbonate. Here's a great recipe for a raw diet, developed by a vet who has made feline nutrition her life passion, so it's well balanced:
Perhaps that will help your cat's ravenousness!
