I do not feed raw so hope that some of the TCS members who do, will also comment.
I took a look at the site, my only comment would be 1) unless you are comfortable with feeding garlic (which I do not), you'd want to avoid one of the veggie add-on's that you can purchase seperately (it lists garlic), 2) they make it clear you need to supplement their products, which means you really need to know what is needed.
Here are some good sites that discuss feeding raw:Little Big Cat
and Feline Future
