You know that Filou was diagnosed with kidney failure a year ago. He's doing well with weekly sub-q fluids. At the moment there is no difference in behavior or whatever.

The diet food he likes best is Royal Canin Renal- the dry food. He didn't like the Hill's K/D

There is a very good website in which you can learn all about this condition:

All the best for Ripley- the diet and the fluids will give him some more quality lifetime.
