She's on a low-protein diet?

It seems from what I read here that many cats like Royal Canin food. They have a low-protein food, and it might be less expensive than some of the other vet foods.

With the right diet and fluids, Priscilla can have a good life for many more years. Did the vet have any suggestions?

I think someone here on PT posted a link to a site on cats with kidney problems.
Hopefully they will again.

Good luck with the little girl! Scritches and tummy rubs!
