Cats are living longer than ever before — a 15-year-old cat is now commonplace in many veterinary practices, and cats regularly reach 18-20 years. Managing the welfare of senior and geriatric cats requires understanding age-related changes and providing appropriate support for a genuinely good life in the senior years.
Feline aging classifications: mature (7-10 years), senior (11-14 years), geriatric (15+ years). Significant age-related physiological changes begin in the senior years: kidney function declines, thyroid function may become abnormal, arthritis develops, dental disease accumulates, sensory acuity decreases. Understanding these changes is the foundation of welfare-positive senior cat management.
Osteoarthritis is vastly underdiagnosed in cats — studies using radiography find degenerative joint disease in 70-90% of cats over 12 years, yet only a fraction receive analgesia. Cats mask pain extremely effectively and owners frequently attribute reduced activity and jumping to "normal aging." Signs of arthritis-related pain in cats include: reduced jumping height and frequency, reluctance to use stairs, changes in grooming (difficulty reaching areas), changes in interaction and demeanor, and — crucially — subtle facial grimace measurable by the Feline Grimace Scale.
NSAIDs (meloxicam, robenacoxib), gabapentin, and polysulfated glycosaminoglycans all reduce arthritis pain in cats. Treatment significantly improves activity levels and interaction — behavioral improvements owners often describe as their cat "becoming young again."
Feline cognitive dysfunction syndrome (CDS) — analogous to Alzheimer's disease — affects an estimated 28% of cats aged 11-14 years and 50%+ of cats 15+ years. Signs include: disorientation, altered sleep-wake cycles (yowling at night), reduced interaction, house soiling, and changes in appetite. CDS affects welfare significantly — cats with CDS show anxiety, confusion, and disrupted social behaviors.
Environmental enrichment, predictable routines, and pharmacological management (selegiline where available) support welfare of cats with CDS. Night waking is a significant welfare indicator requiring management to ensure both cat and owner wellbeing.
Senior cat welfare benefits from environmental modifications that accommodate reduced mobility and sensory acuity:
Regular quality of life assessment using validated tools helps guide management decisions for senior cats. The HHHHHMM scale provides a framework for monitoring whether quality of life remains acceptable. Crucially, "time-limited" conditions like severe pain or cognitive dysfunction should prompt welfare conversations about euthanasia timing — the welfare imperative is to offer euthanasia before suffering becomes severe, not after.
