Indoor cats face a welfare paradox — protected from outdoor dangers but potentially deprived of the hunting, exploration, and territorial behavior their biology demands.
Indoor cats live longer but may experience reduced wellbeing from inability to express natural hunting, territorial, and exploratory behavior. Obesity, lethargy, over-grooming, and behavioral problems are markers of environmental inadequacy in cats who evolved as active predators. The welfare solution is not simple outdoor access — outdoor cats face real hazards and have documented impacts on wildlife. Providing indoor environments with adequate stimulation through vertical space, puzzle feeders, regular interactive play, and appropriate social housing addresses indoor welfare needs without the hazards and ecological costs of outdoor access.
