Ladybeloved, my Filou also has kidney problems. He loves the Royal Canin but there are other diet foods. Many here use Science diet K/D.

THere are lots of infos on this website:

Depending on how advanced Ming's kidney failure is, subcutaneous fluids are recommended.

When the treatment starts I think I would have checked the urea and creatinine level every 4 weeks. With the diet and the fluids they can even be better than now.

All the best for Ming. Filou sends headbumpies.
