Thanks, Pat, for all the info! Thank you Elyse for the prayers!

My vet said -- and I had seen this on the Web -- that while they used to prescribe low protein diets for cats with renal issues, they no longer do that. The high protein is fine as long as it is quality high protein.

Senior kibble was mentioned, but we apparently are not at the stage of needing the prescription food as my vet never mentioned that. (RB Amber cat was on that; or I should say, we tried it, he refused to eat it, lol).

From what I can see, few of the high quality foods even offer a senior cat formula; let alone a kidney specific one. They do puppy and adult "all life stages" formulas and that is all.

So Sparkle will continue on the Taste of the Wild, with canned senior or canned adult mixed in regularly.

I've opted to postpone the fluids for 3 months, see how things go. I HOPE I don't regret this part. Although, I may never know if it was the right decision or not.
