Indoor cats live longer, safer lives, but confinement without adequate enrichment causes frustration, obesity, and behavioral problems that compromise welfare.
Cats confined indoors without adequate enrichment experience frustration from inability to express predatory behavior, which is deeply hardwired. This frustration manifests as aggression, inappropriate play with people, overgrooming, and obesity from inactivity. Single indoor cats may be chronically understimulated without feline companionship. The solution is not outdoor access, which introduces significant risks, but genuinely engaging indoor environments with food puzzles, climbing structures, and interactive play.
