Didn’t work for my cats
My two 12 year old cats have been on Royal Canin Light for years. Changed to this food given their age and they loved it. Unfortunately it caused very loose, yellow, smelly stools. Sought advice and swapped to grain free brand and stools went back to normal within a couple of days. They eat far less of the grain free food and produce far less faeces so won’t be going back to Royal Canin.
