Research overview: the SPIDER framework and goal-directed enrichment programs

Effective enrichment is a structured process, not a collection of toys, and the SPIDER framework, Setting goals, Planning, Implementing, Documenting, Evaluating and Re-adjusting, formalises this cycle. This overview surveys how goal-directed enrichment frameworks guide captive felid programs: defining target behaviours, planning interventions grounded in species biology, implementing them safely, recording responses, evaluating outcomes with behavioural and physiological data, and refining accordingly. It examines the contrast with ad hoc enrichment, the importance of documentation and evaluation that the field historically neglected, and how such frameworks embed enrichment into routine husbandry and animal-welfare management. It discusses safety assessment and avoiding habituation. The synthesis frames structured enrichment processes as the professional standard that turns enrichment from well-meaning novelty into measurable welfare improvement.
