Caring for Aging & Senior Pets

Caring for Aging & Senior Pets

Definition of Aging

The definition of aging has always been difficult to pinpoint. According to the 2021 AAHA (American Animal Hospital Association) / AAFP (American Association of Feline Practitioners) guidelines, the age classifications are as follows:

Cat Age Classifications
  • Mature adult cats: 7-10 years old
  • Senior cats: 10 years and older

Aging is a complex physiological process that occurs gradually over time. Just like humans, cats experience inevitable physical changes as they grow older.

Physiological Changes in Senior Cats

  1. Digestive System Changes
  2. Muscle & Fat Loss
  3. Decline in Sensory Organs
  4. Changes in Vital Organ Functions:
    • Heart & Lung Aging
    • Kidney Function Decline
    • Liver Function Decline
    • Gastrointestinal Changes
    • Behavioral Changes -- Increased sleep duration, decreased activity levels
Important Note

By the age of 12 and beyond, these changes progress silently, often going unnoticed. Studies have shown that:

  • 1 in 5 senior cats (14+ years old) has reduced protein digestibility (<77%)
  • 1 in 3 cats (12+ years old) has reduced fat digestibility (<80%)

This indicates that as cats age, their ability to digest and absorb essential nutrients declines, making dietary adjustments crucial.

Caring for Senior Pets

Regular Health Check-ups

Regular veterinary visits help prevent, detect, and manage chronic diseases early. If diagnosed with a condition, medications and dietary adjustments can help slow disease progression.

Proper Diet Management

Provide a nutritionally balanced diet formulated for senior cats. Adjust feeding strategies to compensate for reduced digestive efficiency and prevent age-related diseases.

Moderate Exercise

Encourage gentle play and movement to maintain muscle strength and mobility.

Pet-Friendly Living Environment

Make adjustments to enhance accessibility (e.g., lower litter boxes, ramps for easy access to favorite spots). This helps reduce joint stress and mobility issues.

Reduce Environmental Stress

Provide quiet, private spaces where senior cats feel secure and undisturbed. Avoid unnecessary changes, such as introducing new pets or frequent household disruptions, which may cause stress and anxiety.

Many pet parents find it difficult to accept that their cat is aging, but aging is an inevitable part of life. As a cat's age, body, and behavior change, the risk of chronic diseases increases over time. Thus, it is every pet parent's responsibility to understand, adapt, and provide the best possible care—ensuring their beloved companion enjoys a comfortable, healthy, and happy senior life.
