Providing appropriate environmental enrichment is one of the highest-impact welfare interventions available for indoor cats, preventing boredom, stress, and associated physical health problems.
Indoor cats without adequate enrichment live in a state of behavioral deprivation. Their predatory drive, territorial instincts, and need for choice and control are all frustrated by static, barren indoor environments. This deprivation contributes to stress-related illness including cystitis, overgrooming, and inappropriate elimination. The welfare impact is real even when cats appear content - low activity and sleeping 18+ hours daily may reflect not contentment but absence of stimulation. Relatively small investments in enrichment produce measurable improvements in both behavioral and physical health outcomes.
