Our take on the Royal Canin Veterinary Diet Feline Urinary SO Loaf in Sauce Wet Cat Food

Royal Canin Urinary SO Loaf in Sauce is a veterinary-exclusive wet food for adult cats with urinary problems. It is formulated to increase urine volume so minerals are diluted, and uses Relative Super Saturation to lower the ions that form stones. It also has reduced magnesium to help dissolve pure struvite stones and stop them reforming. It suits cats with struvite or calcium oxalate crystal risk, but it needs a vet's prescription and is not a food for healthy cats.

About the Royal Canin Veterinary Diet Feline Urinary SO Loaf in Sauce Wet Cat Food

Royal Canin Veterinary Diet Feline Urinary SO is a loaf in sauce wet food for adult cats. It is made to support urinary tract and bladder health, and it requires a veterinary prescription.

The formula increases the amount of urine a cat produces, which helps dilute excess minerals that can cause crystals and stones. Relative Super Saturation (RSS) methodology is used to help lower the ion concentration in urine that contributes to stone formation. It creates a urinary environment unfavorable to both struvite and calcium oxalate crystals.

A reduced level of magnesium helps dissolve pure struvite stones and helps prevent struvite stones from forming or coming back. The food also helps prevent calcium oxalate stones. Feed it as directed by your veterinarian.
