Royal Canin Sterilised Ageing 11+ Dry Cat Food

Senior neutered cats face a dual challenge: the metabolic effects of sterilisation plus the natural decline that comes with ageing. Royal Canin Sterilised Ageing 11+ addresses both with the proprietary HealthyAge7 complex for cats over 11 years old.

The formula supports seven health dimensions: kidney function through adapted phosphorus, joint mobility with EPA/DHA and chondroitin, skin and coat via linoleic acid and zinc, digestive health with prebiotics, cognitive function through tryptophan and DHA, immunity with antioxidants, and appetite through high palatability at appropriate calorie levels.

Available in 400 g, 2 kg and 4 kg bags. Follows on from Sterilised 37 as the senior stage of the neutered cat feeding programme.

When should I switch from Sterilised 37 to Sterilised Ageing 11+?

Switch when your neutered cat reaches approximately 11 years of age. The HealthyAge7 complex in Royal Canin Sterilised Ageing 11+ (V25139) provides targeted support for the specific health challenges of senior cats.

What are the seven dimensions of HealthyAge7?

The HealthyAge7 complex supports:

• Kidneys (adapted phosphorus)
• Skin and coat (linoleic acid, zinc)
• Mobility (EPA, DHA, chondroitin)
• Appetite and weight (palatability with appropriate calories)
• Digestion (prebiotics, digestible proteins)
• Brain and vision (tryptophan, DHA, taurine, vitamin A)
• Immunity (vitamins C and E, beta-carotene)

Is this suitable for neutered cats only?

Yes, this formula is specifically designed for the combined needs of sterilisation and ageing. Non-neutered senior cats may prefer Royal Canin Ageing 11+ Senior, which supports senior health without the sterilisation-specific weight management component.

Why is hydration important for senior cats?

Ageing kidneys work harder to maintain fluid balance, so hydration is especially important for senior cats. Pairing this dry food with wet food helps increase daily water intake, supporting kidney function and overall hydration.

What sizes are available?

Royal Canin Sterilised Ageing 11+ is available in 400 g, 2 kg, and 4 kg bags at Canine & Co.
