I'm so sorry to hear this about Arwen. Kidney disease is scary, and it's an effort to manage , but you get into a routine quicker than you'd think. I started out supplementing Spencer's dry food with home-cooked, since he hated all the store-bought kidney diet food (including the stew) and would only eat it doctored up. I soon found that it was just as easy to home-cook everything. I experimented with all sorts of combinations, always including a primary protein source like lean chicken, turkey or a scrambled/boiled egg, mixed with rice, veggies and an omega-3 gel cap. I avoided corn, but Spencer loved most other veggies– green beans, broccoli, spinach, sweet potatoes, cauliflower, carrots and squashes.
I know that a lot of people use recipes, but I knew what he could have and what he liked, so I just planned my own meals accordingly and gave him a blander portion of what I had. I fixed a lot of stir fries and steamed veggies and grilled a lot. I've never eaten healthier than those last few years with him. His quality of life was good and his kidney values, though elevated, stayed within his "normal" range until almost the end. Hopefully, Arwen responds well to her new diet and has good, happy years ahead!
