Is Royal Canin Urinary SO wet and dry cat food the best option for treating a cat with crystals? I’ve heard some bad things about it and some good. My cat doesn’t really like it but the vet suggested he eat THIS brand only.. which happens to be the most expensive

I think this is a very good food for treating crystalluria, and there are some differences between this food and urinary foods by other companies like Hill's. One difference that comes to mind is the calorie content - Royal Canin SO tends to be lower in calories than Hill's c/d. You may want to ask your veterinarian about the Royal Canin SO Olfactory attraction food which is supposed to be more palatable for cats, or if Bean really seems to dislike it you could ask about switching to another therapeutic diet. There are no over the counter alternatives that are proven to prevent urinary crystals in cats.
