S = SAVORY: Helps stimulate appetite in cats and encourages eating with square-shaped kibble

HIGHLY PALATABLE: Helps compensate for decreased appetite with a highly palatable energy-dense dry cat food formula to reduce meal volume

PROMOTES KIDNEY FUNCTION: A precise antioxidant complex, fatty acids from fish oil, low phosphorus, and targeted protein levels help promote kidney care

MIX WITH WET FOOD: Works in conjunction with a variety of appetite-stimulating Royal Canin adult cat food varieties

Your vet recommended Royal Canin Renal Support S for a reason. This highly palatable dry cat food is specially formulated to care for the kidney health of adult cats under veterinary supervision. “S” stands for Savory, and this formula can help stimulate your cat’s appetite. The square-shaped dry kibble can be mixed with other Royal Canin Renal Support formulas, which have a variety of palatable aromas and dry or wet forms to help find the right combination to get your cat eating again. And the energy-dense diet provides nutritional support in smaller portions, since cats with reduced kidney function have decreased appetites. Plus, it contains a precise antioxidant complex, fatty acids from fish oil, low phosphorus, and targeted protein levels to help support kidney function.

Kidney Care

I have had to use this food for several months and my 17 year old cat prefers it. I also have another 16 yr old and 2 yr old that like it too! The food has given my cats more time and better health

This is the 1st dry cat food my cat has eaten in 3 years. She was put on a renal diet 8 months ago. I was looking for a dry food that I could leave out for the days I have to be away from the house for long periods. As soon as I opened the bag, she couldn't wait to eat a handful and totally ignore the moist food.

Beneficial

My DVM prescribed this formula for Lucy to support her Renal decline two years ago. She did very well on it and it gave her a good quality of life. She lived to almost 15, her final blood panel before her dental procedure show she had improved in her Renal levels. Her dental procedure reveled a fatal tumor and I choose to let her pass peacefully. I would recommend this prescription diet for felines with renal issues.

Resealable bag

The Renal Support S mixed half and half with the Urinary SO is keeping my cat alive and healthy. Her blood work is back in the normal range with this combination.

Cat loves it!

My cat with early kidney disease has been on this diet for a while now. He started on another prescription brand and wasn't a fan of it, so I switched him to Royal Canin and have had no trouble with him being picky about it!

3 cats all eat this

My cats have always gone for Royal Canin dry food but when one needed food for kidney support I was concerned about them accepting this. This actually is a preferred dry food for all of them!! While they all have different styles for wet food I am so pleased they will all eat this one!
