Whether this is your cat’s first urinary issue or she has developed food sensitivities and needs ongoing urinary care, your vet recommended Royal Canin Urinary SO + Hydrolyzed Protein for a reason. This veterinary-exclusive dry cat food was developed to nutritionally support your adult cat’s urinary tract and bladder health. It’s designed with Relative SuperSaturation (RSS) methodology to help lower ion concentration in urine, which contributes to stone formation. This formula promotes a urinary environment unfavorable to the formation of both struvite and calcium oxalate crystals. It also features highly digestible hydrolyzed protein, which helps reduce the risk of stomach and skin signs in cats with food sensitivities. Talk to your veterinarian about keeping your cat on this urinary cat food with Royal Canin Hydrolyzed Protein Treats for long-term urinary tract support.

This multifunction feline diet utilizes a specialized mineral and hydrolyzed protein strategy to support both urinary and allergy management. It is a veterinary-authorized diet frequently considered for cats with urinary crystals who also have food sensitivities.

This is a veterinary-authorized therapeutic diet formulated to meet AAFCO nutritional adequacy standards. It requires authorization from a licensed veterinarian and is not intended to diagnose, treat, cure or prevent any disease.

At a nutritional level, it manages the bladder using the S/O Index while providing hydrolyzed proteins (broken down into tiny pieces) to manage the risk of an immune response. Commonly observed effects include comfortable urination and reduced skin itching. Because it addresses dual goals, strict compliance is a clinical requirement. Owners should avoid giving any other food sources or treats to ensure the trial remains appropriate.

Do I need a prescription?

Yes. This multifunction diet requires professional authorization from a licensed veterinarian. Mixlab ensures all professional standards are met.

How does it help both needs?

Veterinarians discuss this formula because it manages urine pH while using proteins that the immune system is less likely to recognize as a trigger.

Why is the protein "hydrolyzed"?

Hydrolyzing breaks protein down so small that it may be considered in the context of minimizing the immune system's recognition of dietary proteins, which may be relevant when managing the risk of an allergic flare-up.

Can my cat eat this for a food trial?

Yes. Because the protein is hydrolyzed, veterinarians consider this a method for managing urinary health while conducting a food elimination trial.

What monitoring is required?

Your veterinarian will recommend periodic urinalysis and skin assessments. This monitoring ensures the dual nutritional approach remains suitable.
