Cat Welfare and Environmental Complexity: Science 2026

The science of environmental complexity for cats in 2026 provides specific, evidence-based guidance for optimising indoor cat welfare across all five domains of the welfare framework.

Key Facts

Cats require vertical space, hiding opportunities, scratch surfaces, play and foraging opportunities as minimum complexity
Research demonstrates that indoor cats without enrichment show elevated cortisol and reduced positive behaviours
Rotational enrichment maintaining novelty provides sustained engagement beyond initial habituation
Prey-sequence structured play satisfying stalk, rush, catch and carry significantly reduces frustration behaviours
Multi-sensory enrichment including auditory and olfactory stimuli complements visual and physical enrichment

Welfare Considerations

The evidence base for cat environmental enrichment is now robust and specific. Applying this evidence systematically transforms indoor cat welfare from passive provision to active support of species-specific behaviour.

What You Can Do

Assess your indoor cat's environment against the five pillars of feline environmental needs
Introduce rotational enrichment to maintain novelty and sustained engagement
Provide at least two prey-sequence interactive play sessions daily for indoor cats
