"I previously owned a pure white persian and presently own a lilac point Himalayan (referred to in Europe as Colorpoint Persians, of which lilac is one of several colors they are bred in) (and if truth be told -she owns me, not the other way around, as well as the house we share). We have a pact: she brings me joy and happiness, in return for which I keep a roof over head, groom her, and see that her health needs are taken care of, to which ROYAL CANIN PERSION 30 contributes more than just nominally. It is so nutritionally complete that she receives no supplements and at the age of 15+ years, Priscilla (aka Prissy Cat) is as active and energetic as the day I brought her home many years ago. She has not had one single hair ball since I started feeding her Royal Canin Persion 30. None of the other top cat food brands anti-hairball formulas work as well."
