The supplements are fairly reasonable, although, the raw diet recipe that I follow (and after the workshop conducted by a vet the other day, apparently a good one to be following)... some of the ingredients are a little hard to come by, and somewhat expensive at first but they last for a while.
I bought WildTrax in december of last year, it was a four pound can. I'm about half way through it (most of that time, it was only two cats I was supplementing).. it was $18, I think, or thereabouts.
There's a lot of information on www.catinfo.org
Both were recommended by the vet that conducted the nutrition seminar I just went to. She studied with Dr. Pitcairn.
Both of those sites have a recipe. I've found that the catinfo.org works better for me. But, I just started doing the ground up bones. I added a nutritional supplement to basic chopped up chicken thighs and breasts, with about 10 percent of a combo of livers, gizzards and hearts (no more than 5% of that being liver). I'd suggest a different supplement than the wildtrax.. one that is made for raw diets that don't include bone, because it doesn't have enough calcium. You can add some yogurt to get the calcium in, but.. I'm sort of torn on the best way to do that. That's teh reason I personally invested in the grinder (but it took a long time and it was really expensive). Between that and the freezer, it was over $300, but I've made it a lifestyle over here, and it actually will save me money in the longrun. All of that, though, is besides the point. Sorry to ramble..
Try those websites. They're my bible.
