Purina one has a urinary health cat food that my cat likes.
I don't know many specifics but one of our cats had a bladder stone we were told that she needs to always eat c/d by She's never had anymore problems since we have been feeding the cats this expensive food. Cheaper than more surgeries though.
The best food for urinary issues is wet food. Numerous studies have been done and wet food is the best food for cats. Cats have a very low thirst drive, so they don't get enough water when given dry food alone.
Dry food is also very high in carbohydrates and other fattening ingredients. Wet food may seem indulgent, but it really is the best for them. If you can't to wet food, don't get a prescription diet or purina.
Prescription diets almost always are full of ingredients like corn, soybeans, animal fat, by products, and cellolose (which is wood by the way). Purina also is not known for good ingredients. Almost any brand of food that you would buy in a grocery store isn't good for your pet.
Here are some great cat articles on food.
