Raw feeder here
I have been feeding a franken prey style diet for nearly 3 years to all my furmonsters (4 cats, 1 dog).
I do not grind
I do not add supplements (except the occasional fish oil capsule).
I do have a 4 meat rotating diet, and use the 80-10-5-5 rule.
Since I live in the middle of the desert, all our food sources are shipped in.
That means that I am relegated to what I can get at Costco and the asian market.
Unfortunately, there are only 2 "true" butcher shops (their meats are still shipped in, though) in the entire city.
I buy my meats in volume, then vac-pack and freeze large daily portions (daily for all 5 animals).
Each day then, I portion out by meal. This reduces the amount of surface area exposed for any length of time.
I love to hear about how other folks manage their meals, and what they include in their diets.
I think of it as an ever educational experience.
