Seems a few have said on here that the Purina has given some loose poops. Ive had the same with Candy. When she was ill i had her on Royal Cannin stuff for a upset tummy it did the trick.
Slowly introduced the Purina again when she was better ( this is what shed been on when i got her ) and shes better but can still do a loose ish ones. Im going to introduce JWB as the Purina is getting low ish now + its what i give Missy so makes sence to have them both on the same.
