Filou who is only ten has kidney failure as well.
He lives with it for more than 1,5 years now- getting fluids every week and eating diet food.
He hated Hill's k/d but he loves Royal Canin Renal. It comes in little pouches which is good as the cans of Hill's were too much for him and once open he didn't like them
He likes the dry Royal Canin Renal even more. Even Tigris who is not on a diet goes crazy for these kibbles.

All the best for Priscilla.
