Behavior and Cognition of the Senior Cat and Its Interaction with Physical Disease

In cats , age-related pathologic condition and neurologic degeneration can produce changes in activity, vocalization, appearance, appetite, litter box use, sleep–wake cycle, personality, and cognitive ability. These changes can influence the relationship between owner and pet. Although cognitive dysfunction syndrome (CDS) can cause altered behavior later in life, other medical or behavioral causes may mimic these clinical signs or complicate diagnosis. Management and treatment of CDS can be accomplished through pharmacologic intervention, diet and nutritional supplementation, and environmental enrichment aimed at slowing the progression of the disease.
