Food & NutritionMy cat had crystals. Which Royal Canin urinary food should I use?
From Royal Canin's website: "This diet is only suitable for healthy adult cats that do not have a urinary issue or a history of urinary problems. This food is not a replacement for a diet prescribed by your veterinarian." If Elbi has already had a urinary problem, I don't recommend considering switching to the urinary care food. Urinary S/O is designed to encourage more drinking, as well as neutralize the pH of the urine - both of those together tend to almost completely eliminate the chances of crystals forming.
