Bought RC kitten because it was there that the breeder used when I bought my cat. My cat's feces were always loose, almost like diarrhea and often got stuck in the fur, has a Siberian cat with Semi-Longhair. Now with other feed stools are much better. The only compliments the RC kitten is my cat seems to like it.
RC Kitten is an OK feed. My cats liked it but the truth is that it is the aromas that do. Protein-/köttinnehållet is unfortunately poorly and will do basically not to feed a cat with. P21, Orijen, etc. are usually much higher protein levels. Compare for yourself.
