Evidence-based environmental enrichment for indoor cats can meet behavioral needs and prevent the welfare problems associated with under-stimulation.
Indoor cat enrichment has moved from anecdote to evidence, with validated protocols demonstrating significant welfare improvements. Puzzle feeding, interactive play, olfactory enrichment, and vertical space are all well-supported by research. The key is consistency and variety: enrichment that becomes familiar loses value. Rotating enrichment and providing novel experiences maintains engagement and welfare benefit.
