Anything that had any nutritional value has long been lost and changed before it became kibble in extremely high temperatures. That is why every single kibble has artificial vitamins and minerals added to comply to certain standards.
With that said, I looked into Royal Canin urinary, and it contains calcium sulphate and methionine which you are already supplementing her food with. I don't know what change it would make?
I am all for the natural route (raw) with supplementing depending on the condition, but supplements can become pricey and raw feeding needs some knowledge and more work that dropping kibble in a bowl. But for me, it's worth it.
