Cognitive dysfunction syndrome (CDS) in cats is similar to Alzheimer's disease in humans. Understanding its signs and management options is essential for improving welfare in aging cats.
CDS causes genuine distress in affected cats — disorientation, confusion, and disrupted sleep-wake cycles are frightening experiences. Cats who vocalize persistently at night are not being demanding but are often experiencing the confusion and anxiety of cognitive decline. The welfare-appropriate response is diagnosis and management, not behavior suppression. Environmental stability helps — predictable routines, avoiding furniture rearrangement, and providing easily accessible resources reduce the confusion navigating familiar spaces. Dietary support with antioxidants, omega-3 fatty acids, and SAMe may provide modest benefit. The condition is progressive, requiring quality-of-life monitoring to recognize when cognitive changes are causing sufficient suffering to warrant end-of-life consideration.
