I'm glad you got back to us, Lisa; I've been checking the thread every few hours. I'm sorry it's a more serious kind of renal failure and hope you can give Willy plenty more quality time.

Your vet still isn't promoting sub-q fluids? Whenever Sam's counts went high (BUN and Creatinine), and other that of other cats, I always boosted the amount of fluids and found the counts lowering. Fluids will make him feel good too and could increase his appetite. You can use phosphorous binders to lower the phosphorous count, although Willy won't thank you for giving him Maalox. My vet told me that cats become nauseated and feel generally awful when their phosphorous count is high. And, your vet could give you potassium supplements for Willy since that is low.

Are you thinking of a kidney transplant for Willy?
