Disclaimer: Product information and usage guidelines are provided by the manufacturer. Always use products as directed on the label and consult your veterinarian before use if you have any concerns regarding your pet's health.

Directions for Use

  • Adjust for Optimal Weight: Fine-tune daily amounts as needed to help the senior cat maintain a healthy body weight, and consult a vet if the correct daily amount is unclear.
  • Transition Over 7 Days: When switching to this food, slowly increase the new food while reducing the old each day over a full week to prevent digestive discomfort.
  • Fresh Water Always: Keep fresh drinking water accessible to the cat at all times throughout the day alongside every meal.
  • Review With Vet at Every Checkup: A senior cat's nutritional needs can shift as it continues to age, so discussing the feeding plan with a vet at every routine visit helps keep daily amounts appropriate over time.

Additional Information

Precautions

  • For Cats 11 Years and Older Only: This formula is designed specifically for adult cats 11 years of age and older. It is not appropriate for kittens or pregnant and nursing cats.
  • Not for Kittens or Pregnant Cats: Kittens and cats that are pregnant or nursing should be switched to Hill's Science Diet Kitten or Hill's Science Diet Kitten Indoor dry cat food during those life stages.
  • Count All Daily Food: Treats and supplementary foods given alongside this kibble should be counted toward the total daily calorie intake to prevent unintentional overfeeding in senior cats.

Possible Side Effects

  • Digestive Sensitivity on Transition: Moving to a new food too quickly may cause temporary digestive discomfort, making the full 7-day gradual transition important before fully replacing the previous diet.

Storage Information

  • Store in Original Bag: Keep the food in its original bag after opening, as the bag provides a fat barrier that helps retain the best flavor and freshness.
  • Cool and Dry Environment: Store in a cool, dry place below 100°F (38°C) to prevent vitamin degradation and oxidation of fats that can lead to rancidity.
  • Keep Packaging Away: Store the bag and all packaging safely out of reach of both pets and children at all times to prevent potential suffocation hazards.

Shipping & Return

We offer ground, express, and priority delivery; see our shipping policy for details.

Frequently Asked Questions

Q1: What makes this Senior 11+ formula different from the Hill's Adult 7+ Chicken Recipe dry cat food?

Ans: The 11+ formula is calibrated for the more advanced nutritional needs of cats entering their senior years at 11 and beyond. It contains a special ingredient blend to help keep older cats agile and interactive, and notably higher vitamin E at 925 IU/kg compared to the Adult 7+ formula. It also delivers a higher omega-3 content at 1.57% dry matter, reflecting the greater joint and cellular support needs of cats in their oldest years.

Q2: How does this Senior 11+ formula support joint health in aging cats?

Ans: This formula provides optimal levels of key nutrients specifically to support joint health alongside eye, heart, and kidney health in cats 11 years and older. The total omega-3 fatty acid content at 1.57% dry matter from fish oil and flaxseed contributes to joint comfort and cellular health support. Hill's highlights joint health as one of the four key organ systems this formula is designed to address in senior cats.

Q3: Why does this senior cat food have a higher caloric density than most adult cat formulas?

Ans: At 4044 kcal/kg and 504 kcal per cup, this formula has a notably higher caloric density than many standard adult cat dry foods. This is because senior cats, particularly those 11 years and older, can struggle to maintain body weight and muscle mass as their metabolism and digestive efficiency change with age. A more calorie-dense formula helps ensure these cats receive adequate energy and nutrition from the amounts they are able to eat.

Q4: What is the role of ActivBiome+ Multi-Benefit in this senior cat formula?

Ans: ActivBiome+ Multi-Benefit is Hill's proprietary blend of prebiotic fibers and antioxidants that supports three key areas simultaneously in senior cats: digestion, immune system function, and organ health. For cats 11 years and older, maintaining a healthy gut microbiome and strong immune response is particularly important as the body's natural defenses and digestive efficiency can decline with advancing age.

Q5: Is this Hill's Senior 11+ cat food suitable for a cat that has always eaten the Adult 7+ formula?

Ans: Yes, once a cat reaches 11 years of age, transitioning from the Adult 7+ formula to this Senior 11+ formula is the appropriate next step. The transition should be completed gradually over 7 days to allow the digestive system to adjust comfortably. The 11+ formula is specifically calibrated for the more advanced aging needs of cats in this life stage, including the special ingredient blend designed to support agility and alertness.

Q6: Does this Senior 11+ formula support kidney health and why is that important for older cats?

Ans: Yes, Hill's specifically lists kidney health as one of the four key organ systems this formula is designed to support through optimal nutrient levels. Kidney health becomes increasingly important to monitor in cats as they age, as kidney function can decline in senior cats. The controlled phosphorus level at 0.68% dry matter reflects a mindful approach to kidney support appropriate for healthy senior cats eating this formula as their daily diet.

Q7: Can I mix this Senior 11+ dry food with a Hill's wet food for added moisture?

Ans: Yes, pairing this kibble with a Hill's Science Diet wet food designed for senior cats adds mealtime moisture and texture variety, which can be particularly beneficial for senior cats that may drink less water as they age. Increased moisture intake supports kidney function and overall hydration. When combining wet and dry food, adjust portions of each to keep total daily calorie intake within the appropriate range for the cat's current weight.
