hi there, I am with a rescue here in Utah and have a cat Max (approx 10-12) dlh flamepoint Siamese....only has about 25% function in each kidney. He is very picky about eating and I do not believe in feeding him the prescription diets as most of the ingredients are crap however I do not know what I really should be feeding him. He’s currently getting canned organic chicken food from Costco because he won’t eat it. But I did read recently that the Pea protein or pea flour is not good for him. He recently stopped eating and I thought it was the end I took him into the vet and his glucose was 1400! He also likes Weruva packets.
