Quick answer

Choose Royal Canin Ageing 15+ for cats 15 years and older, and Ageing 11+ for cats 11 to 14 years old. The 15+ formula is tailored to the more advanced needs of very senior cats, while 11+ supports the early senior years.

Why the age split matters

Cats' nutritional needs change as they age. Royal Canin divides its senior line into 11+ and 15+ to address the different health challenges cats face in early versus late seniority. The 11+ formulas support vitality and maintain organ function, while the 15+ recipes are designed for cats who may have reduced kidney function, lower energy, and more sensitive digestion.

Dry vs wet: texture and hydration

Both age ranges offer dry kibble and wet food options. Dry food is convenient and helps with dental health through crunching, while wet food provides extra moisture, which is especially beneficial for senior cats prone to dehydration or urinary issues. The 15+ wet food comes in chunks in gravy, which is easy to eat for cats with dental problems.

Trade-offs at a glance

  • Age range: Ageing 11+ is for cats 11-14 years old; Ageing 15+ is for cats 15 years and older. Using the wrong range may miss key nutritional adjustments.
  • Format choice: Both ranges offer dry and wet options. Dry food is more calorie-dense and helps with dental health; wet food adds moisture and is softer. The 15+ wet food is especially gentle for older cats with dental issues.
  • Nutritional focus: The 15+ formula is more specialized for advanced aging concerns like kidney support and reduced calorie needs, while 11+ focuses on maintaining vitality and organ function.
