Teresa - I feel like I run a little kitty restaurant here! Their main food is Nature's Variety Instinct Raw either rabbit or chicken. They also eat some Fancy Feast classic - but they don't love it. Sometimes they get a little ziwi peak lamb. Sam was quite the kibble addict when we started this whole process and that seems to help when he gets a craving for something crunchier. And Stella and Chewy's chicken. I am sparing on that one since I don't have good information about the actual values.
Both cats are rather picky, but I've found that sprinkling a little Fortiflora on top will get them to try just about anything. I don't know what it is about that stuff, but they both go crazy for it. It really helped in getting Sam off the kibble, and onto wet food.
Do you already have the food chart?
http://catinfo.org/docs/FoodChartPublic9-22-12.pdf That's a good place to start in looking at some of the values, and figuring out what Buddy can tolerate. I found figuring out the right food to be one of the most challenging (and one of the most important) parts of this whole process.
Sorry to see you were up so late/early last night. I hope you can get some rest today!
