So I feed my dogs/cat raw, and just got a new source that is grass fed but grain supplemented for them, and is incredibly low cost. I've mostly been doing grain fed with them, unfortunately. Even the supplemented meat just looked like it came off a whole different animal. I know it's not the best, but I will probably need to keep them on that price-wise (it's not USDA but it's $1.25/lb for chunked beef - absolutely insane). Long story short, I just had my first raw beef. It was only a sliver, but I had to try it. It took me a while but I finally just went for it, and it was pretty delicious.
Right now, I feel like I'm starting to open up some pretty good prospects. Whole Foods is a possibility, but my first target is now
http://www.southsidemeatmarket.com/, which is actually a couple minutes closer to me, and says all their beef is grass fed and then finished off. The wording was weird to me, so I'm going to confirm it is 100% grass fed before I pick anything up.
Also, vermontgrassfedbeef.com has confirmed that they can have my order fresh/never frozen as long as I get it in by sunday for cutting at the butcher on monday and sending on tuesday. They also have marrow bones and can get beef suet and pork fat. Given their prices, I'm thinking this place will be perfect to buy in bulk if I manage to mostly convert over. I'll let you know!
I'll keep the oysters and clams in mind, though my current projected idea is to possibly slowly convert over to beef and possibly some other land mammals, and once I'm comfortable there to maybe try those and then move on to fish as well. I do eat sashimi now, but I'm not as comfortable getting some random wild caught from the store, when I know my body isn't in the best shape to protect itself.
