Cat Cognitive Dysfunction Syndrome in Senior Cats

Feline cognitive dysfunction syndrome is analogous to dementia in humans. Recognising signs early enables supportive care that maintains quality of life.

Key Facts

CDS affects an estimated 28% of cats aged 11-14 and over 50% of cats over 15
Signs include disorientation, altered sleep patterns, reduced grooming, and vocalisation at night
Diagnosis is clinical, based on ruling out other causes of behavioural change
Environmental enrichment and routine can slow progression
Some cats benefit from dietary supplements or medications including selegiline

Welfare Considerations

Cats with CDS experience confusion, anxiety, and disrupted sleep that affect wellbeing. Night-time vocalisation reflects disorientation and distress. Many owners tolerate these signs without seeking help, not realising the cat is suffering. Veterinary assessment can identify contributing medical conditions and advise on management strategies. Maintaining familiar routines, nightlights, easily accessible litter trays, and feeding stations supports affected cats.

What You Can Do

Schedule annual senior cat health checks from age 10 onwards
Report behavioural changes to your vet rather than attributing them to normal ageing
Maintain consistent daily routines to reduce confusion
Keep food, water, and litter trays close together and easily accessible
Discuss supplements and medications with your vet if signs are progressing
