Feline Cognitive Dysfunction: Supporting Aging Cat Welfare

Feline cognitive dysfunction syndrome (CDS) causes dementia-like signs in older cats, requiring welfare-focused management to maintain quality of life.

Key Facts

• CDS affects approximately 28% of cats aged 11-14, rising to over 50% in cats over 15
• Signs include disorientation, night-time vocalisation, altered sleep patterns, and house soiling
• Night-time yowling is distressing for both the cat and owners and is treatable
• Selegiline and dietary supplements may slow progression in early CDS
• Environmental modification and routine maintenance are the cornerstones of welfare management

Welfare Considerations

Feline cognitive dysfunction causes welfare harms through confusion, disorientation, and behavioral changes that signal genuine neurological decline. Cats with CDS may appear lost in familiar environments, stare at walls, yowl at night (often indicating pain, disorientation, or anxiety), and lose litter training. Night-time yowling — one of the most welfare-impactful signs for both cat and owner — can reflect pain from concurrent conditions, disorientation, or anxiety, and requires systematic assessment and treatment. Welfare management includes: maintaining strict daily routines, nightlight provision to reduce disorientation, environmental simplification, pain management for concurrent conditions (arthritis is common in this age group), and pharmacological treatment of anxiety and cognitive symptoms.

What You Can Do

• Assess any night-time yowling for pain (arthritis, dental disease) before attributing it to CDS
• Maintain strict daily routines to reduce disorientation from unpredictable schedule changes
• Provide nightlights in rooms where your cat sleeps to reduce confusion in darkness
• Discuss selegiline or dietary supplements with your veterinarian for early cognitive decline
• Use quality of life assessment tools monthly to track progression and guide care decisions
