Product Description

Hill's Prescription Diet k/d Kidney Care with Ocean Fish Dry Cat Food is clinically proven to improve and extend quality of life in cats with kidney disease.

How to Use

Directions for Use

• Veterinary Prescription Required: This is a prescription therapeutic diet; a valid veterinary prescription is required before purchase and it must only be fed under veterinary supervision.
• Feed Exclusively for Best Results: For maximum kidney care benefit, feed k/d exclusively as the sole diet; dry and wet k/d formulas may be combined or fed concurrently as directed by your veterinarian.
• Transition Gradually over 7 Days: Mix increasing amounts of this new food with decreasing amounts of the old food over 7 or more days to minimize digestive disruption during the dietary change.
• Ask Your Vet for Specific Daily Amounts: Daily feeding recommendations on the packaging are a starting point only; your veterinarian will advise on the correct daily amount based on your cat's weight, body condition, and kidney disease stage.
• Feed Consistently Over Time: This diet only works well when fed regularly for a long period, not just occasionally.
• Monitor and Adjust Portions: Watch your cat's body condition often and ask your vet before changing daily food amounts.
• Always Provide Fresh Water: Keep clean water available at all times, as proper hydration is especially vital for cats with kidney disease.

• Do Not Feed to Other Pets: Only feed this food to the cat for whom it was specifically prescribed; do not share with other cats or pets in the household without separate veterinary authorization.
• Feed Regularly Without Gaps: This diet works best when given consistently over time, as skipping feeding days weakens its ability to slow kidney disease.
• Schedule Routine Vet Testing: Regular blood and urine checks help track kidney health and confirm the diet still suits your cat's changing needs.
• Store Packaging Safely Away: Always keep the food bag and packaging somewhere cats and children cannot reach it to avoid any suffocation risk.

Possible Side Effects

• Expect Brief Digestive Changes: Some cats may have loose stools or mild stomach upset when first switching to this prescription diet.
• Act Fast on Appetite Loss: Kidney disease can reduce appetite; contact your vet if your cat refuses to eat this food for more than 48 hours.
• Track Weight During Transition: Body weight may shift early in dietary management; speak to your vet if loss seems too fast or excessive.

Storage Information

• Store in a Cool, Dry Place: Close the bag properly and place it in a spot that stays cool, dry, and out of direct light, helping it stay fresh and hold onto its nutritional value.

Frequently Asked Questions

Q1: How does Hill's k/d Ocean Fish dry food help cats with kidney disease?

Ans: Hill's k/d works on multiple fronts: ActivBiome+ Kidney Defense prebiotics activate the gut microbiome to protect kidney function, controlled phosphorus and low sodium reduce the kidney workload, and therapeutic omega-3 fatty acids and L-carnitine help protect kidney and heart function while supporting lean muscle maintenance.

Q2: What is E.A.T. technology in Hill's k/d Ocean Fish cat food and why is it important?

Ans: Enhanced Appetite Trigger (E.A.T.) is a clinically tested technology developed by Hill's that helps stimulate appetite and encourage cats to eat more. Cats with kidney disease are particularly at risk, as they frequently go off their food, which can lead to harmful weight drop and muscle deterioration if not properly managed.

Q3: Is the Ocean Fish flavor of k/d nutritionally different from the Chicken flavor?

Ans: Both the Ocean Fish and Chicken k/d dry formulas deliver the same core kidney-supporting nutrition, including ActivBiome+ Kidney Defense, controlled phosphorus, low sodium, and high essential amino acids. The Ocean Fish option simply gives cats who prefer fish-based proteins a tastier way to get the same therapeutic benefits.

Q4: Can I mix Hill's k/d Ocean Fish dry food with any of the k/d wet food varieties?

Ans: Yes. Hill's k/d dry and wet formulas can be mixed or fed concurrently. Combining both formats increases palatability and moisture intake, which is especially beneficial for cats with kidney disease who may need extra encouragement to eat and stay hydrated. Confirm the right daily combination with your veterinarian.

Q5: Why is consistent long-term feeding important for Hill's k/d to work effectively?

Ans: Kidney disease is a progressive, irreversible condition that requires ongoing management. Consistent daily feeding of k/d is critical because the therapeutic benefits — including microbiome activation, phosphorus control, and amino acid support — accumulate over time. Intermittent feeding reduces the formula's ability to slow disease progression and protect kidney function.

Q6: Do I need a prescription to purchase Hill's Prescription Diet k/d Ocean Fish dry cat food?

Ans: Yes. Hill's Prescription Diet k/d requires a valid veterinary prescription before purchase. Your veterinarian must diagnose your cat with kidney disease and recommend this diet as part of a supervised long-term management plan before you can obtain it from a pharmacy or pet retailer.

Q7: How is Hill's k/d Ocean Fish different from regular adult cat food for a cat with kidney disease?

Ans: Regular adult cat food is not formulated to manage kidney disease and typically contains much higher levels of phosphorus and protein that can accelerate kidney damage. Hill's k/d is specifically designed with controlled phosphorus, low sodium, therapeutic prebiotics, and kidney-protective omega-3 fatty acids to slow disease progression and improve quality of life.
