I like the raw diets. My cats get a lot of raw food. However, they are not appropriate for all cats; for instance, giving raw meat to a cat with inflammatory bowel disease can result in a serious infection because the gut defenses are not intact.
Before switching to raw (or even adding raw), do enough research to understand the risks and benefits. There is a ton of info on the internet, it's very easy to find!
