Litter box environment is a critical but often neglected welfare factor for domestic cats, with inadequate provision causing both house soiling behavior and genuine psychological stress in affected animals.
Litter box welfare connects to both the cat's subjective experience and the human-animal relationship. Cats eliminated outside the box do so because something about the available toileting options is aversive - pain (urinary disease), spatial problems (too few, wrong location), or sensory aversion (scented litter, covered box). The welfare cost is borne by the cat, who experiences the aversion that drives them to seek alternatives, and by the relationship, which deteriorates when inappropriate elimination causes owner frustration. Welfare-centered litter box provision treats this as a serious behavioral need requiring evidence-based management rather than a discipline problem requiring punishment.
