Excellent!:
If you have a cat, you know how they sometimes struggle to bring up hairballs (especially longhairs)--and how they sometimes regurgitate their food. After getting tired of finding "yucky stuff" around the house, we decided to try Science Diet Feline Hairball Control. We add it to the Purina Indoor Cat formula, and have been using it for several weeks now. NOT ONCE have we heard our cats hacking or have discovered "throw up". Amazing! Not only that, they LOVE the taste of this food! As soon as I bring out the Hairball Control food to add atop the Purina food, they come RUNNING into the kitchen to eat it! Highly recommended!
