Indoor cats live safer but behaviorally impoverished lives without active enrichment. Meeting their predatory, social, and environmental needs is a fundamental welfare responsibility.
Keeping cats indoors protects them from traffic, predators, and disease, but it creates a welfare obligation to compensate for what is lost. A cat confined to a small apartment without enrichment, vertical space, or regular interactive play is environmentally deprived. The signs — overeating, overgrooming, aggression, or excessive sleeping — are often normalized as personality rather than recognized as welfare signals. Every indoor cat deserves an environment that allows them to express the full range of feline behavior.
