Indoor cats face significant welfare challenges from environmental restriction, requiring deliberate enrichment to support their hunting, climbing, and exploratory instincts.
Confining a cat indoors removes the behavioral opportunities - hunting, territory patrol, novel environment exploration - that define normal feline life. Without deliberate enrichment, indoor cats experience chronic understimulation that manifests as boredom, frustration, and stress-related health problems. The welfare of indoor cats is entirely dependent on owner provision of environmental complexity. Even simple enrichment such as daily interactive play sessions and puzzle feeders dramatically improves welfare outcomes.
