Stimulates aging cats’ decreasing appetite with highly palatable dry kibble

Whether this is your cat’s first urinary issue or they need ongoing urinary care, your vet recommended Royal Canin Urinary SO Aging 7+ and Calm for a reason. This veterinary exclusive dry cat food was developed to nutritionally support your aging cat’s urinary tract and bladder health. This formula is designed with Relative Super Saturation (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 specialized nutrients to help your older cat who may be demonstrating fearful behaviors, and a highly palatable texture to stimulate a decreased appetite and encourage regular eating. Lower urinary tract issues may be a recurring concern for some cats. Talk to your veterinarian about keeping your cat on this urinary cat food for long-term urinary support. And ask them about Royal Canin Urinary SO Aging 7+ and Calm wet cat food and treats to complement your cat’s diet or for mixed feeding.
