Thanks for the recommendation on the Wilderness food. I went to the petstore and oh my gosh, there are so many different foods for cats!! I ended up getting a bag of dry grain free Chicken and Green pea (George can eat this too- he has allergies but this food will work for him). I'm going to also pick up some higher protein wet food (higher than the not so great Friskies wet food Oliver's been getting) tomorrow because I've been reading online and found this really interesting article that talks about how western medicine might have it wrong in prescribing low protein food for kidney cats. It also recommends acupuncture. I wish I had the funding for that but for now that will have to wait. But I might look into the herbal treatment in conjunction with the mostly wet, high protein food. If you read the article it writes about two types of kidney problems, 'inflammatory' and/or 'deficient/ischemic'. The vet didn't say which he had but just said 'kidney insufficiency' although she did mention that the bloodwork showed some inflammation 'somewhere' in his body. If he has the inflammatory type, the vet who wrote the article advises medium protein (not low though) along with acupuncture and herbs.

If anyone's interested or has a cat with kidney issues, here is the article:

Seems to make sense and I'm going to try this approach with Ollie. Hoping this will help him out a bit.
