Indoor cats require carefully designed environments to meet their behavioural needs, with insufficient enrichment linked to stress, obesity, and behaviour problems.
Indoor cat welfare depends fundamentally on environmental design. Cats are obligate predators with strong hunting drives that do not disappear in domestic settings. Providing outlets for predatory behaviour through interactive play, puzzle feeding, and hunting simulation directly addresses behavioural needs. Vertical space addresses cats' natural desire to observe from height. Litter tray access, refuges for retreat, and predictable routines reduce stress. An enriched indoor environment can provide good welfare; an unstimulating one causes chronic stress even when physical needs are met.
