I used to feed NV raw before I made my own, but was just too expensive. Yes, it does contain SOME veggies, but not enough to be significant and is, IMO, better than any canned because the cats are getting their nutrients in their natural form and not through added chemically made nutrients.
I am not familiar with Carnovora, but from their website, they are on the right track for feeding cats what they should be eating.
I do not add any veggies to my homemade raw, but all my cats do get outside and they all do eat grass.
The only thing about premade raw for me (and it is great for people who don't want to make their own), is that I don't control the ingredients(especially the bone to meat ratio) and it may be frozen longer than I like it to be.
