Do you have a cat at home? Is that cat a breed that has special dietary requirments to maintain its health? You may find that you like the Royal Canin cat food line as much as I do.
With a Persian in my home, hair balls are a norm. If the cat is not choking on them, I am picking them off of my clothing. 
The Royal Canin 
Persian food is designed with your cat in mind. A little bit of info from the manufacturer:
      
                              
                                                                        
                                                                        
                                        
            
                                         
                    
        
        
          
          
SPECIAL LONG HAIR
A long, luxurious coat, with a dense undercoat, is the hallmark of 
the Persian cat. PERSIAN contains nutrients which help support the 
skin’s role as a “barrier” and maintain skin and coat health. Formula 
enriched with Omega 3 fatty acids (EPA & DHA) and Omega 6 fatty 
acids.
      
 
                              
                                                                        
                                                                        
                                        
            
                                          
                    
        
        
    
          
              HAIRBALL REDUCTION
          
              
    Due to the length and density of their coat, Persian cats 
routinely swallow a large quantity of hair during grooming. PERSIAN 
contains fibers which help stimulate intestinal transit and naturally 
limit hairball formation.

 digestive sensitivity, with highly digestible proteins (L.I.P.*), 
prebiotics and fibers to help support a balance in the intestinal flora.

With just a small sample size package provided, I could not provide a comprehensive review. Since my picky cat actually ate the sample without any hesitation, I splurged and bought a bigger bag. With that being said, I have noticed a difference in my cats fur. It has more sheen and she does not seems be yarf up bug balls of gooey fluff as often.
I am hoping with a few more weeks of use, I may notice even more of a change.
