Health & WellnessMy cat has kidney issues. Is vet-prescribed food best or supplements?
There is a lot of misconception when it comes to pet food. Grains are not bad for pets as long as they are the right kind, high-quality and easy to digest. They provide many essential amino acids that are not found in animal products. Royal Canin and Science Diet are both high quality brands with lots of research, data and good quality control.
Switching to the recommended diet is the best thing you can do for Mercy. The diet contains controlled protein, controlled phosphorus, controlled potassium and additional omega three fatty acid supplements as well as antioxidants. You can certainly supplement her as it is not likely to hurt but the main control for kidney disease will be found with the protein and phosphorus. I hope this helps and please feel free to post any additional questions.
