I have a white indoor cat and even brushing him every day I still had hair everywhere. A new young vet interning at my vet's office told me to change the cat's food to holistic food. He said that will help with the shedding. I switched the food to Blue brand and I can tell a big difference not having so much shedding. I switched my dog to Blue and noticed a big difference in less poop from them both! My dog shedding problem has reduced too. Blue has no filler so more is digested.
