Indoor cats face significant behavioral deprivation in standard household environments. Evidence-based environmental enrichment addresses the five domains of cat welfare and reduces behavioral problems related to understimulation.
Environmental enrichment for indoor cats addresses a fundamental mismatch between the environment evolution prepared them for and the one most companion cats actually inhabit. Cats are specialized predators with behavioral drives for hunting, territorial marking, and vertical space use that are simply not met in the average apartment or house. The behavioral consequences of this mismatch — urine marking, aggression, destructive scratching, excessive vocalization, and overgrooming — are frequently treated as behavioral problems when they are actually welfare signals. Effective enrichment does not require expensive equipment: food puzzles can be made from toilet paper rolls; hunting simulation requires only a feather wand; vertical space can be created with shelves. The critical element is the owner's understanding that cats need behavioral engagement, not just food, water, and shelter.
