As cats grow older, their nutritional needs change. A balanced diet can help maintain muscle mass, support healthy organs, improve digestion, strengthen the immune system, and manage age-related conditions.
Cats are generally considered senior at 10 years of age and older, although some cats may begin showing age-related changes earlier. Proper nutrition and routine veterinary care can help your cat remain healthy and comfortable throughout their senior years.
Important: Every senior cat has unique nutritional needs. Consult your veterinarian before making significant changes to your cat's diet, especially if they have a chronic health condition.
Proper nutrition helps support:
❤️ Heart health
💪 Lean muscle maintenance
🧠 Brain and cognitive function
🦴 Healthy joints and mobility
🛡️ Immune system function
👀 Vision health
✨ Healthy skin and coat
💧 Kidney and urinary tract health
⚖️ Healthy body weight
🦷 Dental health
A healthy diet, daily activity, and preventive veterinary care can help improve your cat's quality of life and support healthy aging.

Both obesity and unintended weight loss are common concerns in senior cats.
A healthy senior cat should have:
✔ Easily felt ribs with a thin layer of fat

Monitor your cat's weight monthly and report unexpected changes to your veterinarian.
Nutrition plays an important role in managing many age-related conditions, including:
Chronic kidney disease
Hyperthyroidism
Diabetes mellitus
Arthritis
Heart disease
Dental disease
Cognitive dysfunction
Obesity
Your veterinarian may recommend a therapeutic diet designed specifically for these conditions.
Most cats are considered seniors at around 10 years of age, although individual aging varies.
Weight loss may result from decreased appetite, dental disease, kidney disease, hyperthyroidism, diabetes, or other medical conditions. Schedule a veterinary examination if you notice unexpected weight loss.
Many healthy senior cats benefit from increased amounts of highly digestible, high-quality protein to help preserve muscle mass. However, dietary recommendations should always be individualized based on your cat's health status.

Senior cats should receive veterinary examinations at least every six months, or more frequently if recommended.
Routine care may include:
Wellness examinations
Blood work
Urinalysis
