I hope Vader is doing ok.
You may be interested in a couple of formulas I have. They are non-kibble, do not contain any processed ingredients, wheat, soy or sugar or chemicals. One is Rolled Oats, dehydrated veggies, garlic with a packet of vitamin/mineral supplement. These Rolled Oats only contain 4% fat and none of the other ingredients contain any discernible amount of fat. The other formula is Brown Rice with the remainder of the ingredients (veggies, etc). Brown Rice contains less than 1% fat. These formulas are a great compromise between the (horrible) commercial processed food and feeding raw (more preparation than my formulas). You can read about them here California Gold I also have free samples of each formula.
