Indoor cats face particular enrichment challenges as they lack the natural stimulation of outdoor environments, making intentional provision of behavioural outlets essential for psychological wellbeing.
Indoor cats that lack enrichment may develop behavioural signs of chronic stress and frustration including overgrooming, inappropriate elimination, aggression, and repetitive behaviours. These are not personality problems but welfare signals that the environment is failing to meet the cat's needs. Enrichment provision should be varied and rotated regularly to maintain novelty value, and should target each phase of the cat's natural predatory sequence.
