Nutrition has been the cornerstone of long-term support for pets with kidney conditions. Nutrition can also play a key role in managing cats' mobility, reducing clinical signs and improving weight-bearing ability in cats.

Being proactive and managing both conditions with nutrition can have a lasting impact on cats' health.

Prescription Diet k/d + j/d combines the proven nutrition of Prescription Diet k/d for Kidney Care with the technology and efficacy of Prescription Diet j/d for Mobility. It's formulated with ActivBiome+ Kidney Defense, a proprietary blend of prebiotics shown to activate the gut microbiome to help protect kidney function. It also features Enhanced Appetite Trigger (E.A.T) to stimulate appetite and increase food intake. This dry food is made with chicken flavor and has an irresistible taste that your cat will love.

Prescription Diet k/d + j/d is clinical nutrition to improve and lengthen quality of life and increase mobility in cats.

How it helps:

  • Nutrition to help protect vital kidney function and increase ability to run, climb and jump
  • Nutrition to help manage the invisible changes within the intestinal tract that impact kidney function
  • Nutrition to help build muscle mass and help maintain energy and strength
  • Stimulates appetite & increases food intake
  • S+OXSHIELD: Formulated to promote a urinary environment that reduces the risk of developing struvite & calcium oxalate crystals

How it works:
