Yes I think it would work for kittens. One of my cats in particular makes a BIG PRODUCTION out of using the litter box and when he used this one believe me there was much more on the floor than in box!
Thank you for your well researched comment. One of my cat's was recently diagosed with Feline Diabetes and he needs to be on a low carb diet. I will definitely try this product.
Almost all the ingredients are BAD. In order for this variety: Chicken By-Products (Gross), Brewers Rice (carbs are not good for cats), Corn Gluten Meal, Ground Whole Grain Corn etc. etc. etc. Hills Science Diet is downright unhealthy!
