Cats pee on clothes for several reasons, often linked to comfort, stress, territory marking, or health problems. Clothes carry their owner's scent, which can be comforting and feel safe for cats, so they may pee on clothes as a way to mingle their scent or feel secure. Stressful changes in the environment, such as moving or new pets, may cause anxiety-driven urination outside the litter box. Territorial marking behavior is another common cause, especially in multiple-cat households, where males might spray urine to claim space. Lastly, medical issues like urinary tract infections or bladder problems can cause inappropriate urination if the cat experiences discomfort while peeing in the litter box. Ensuring the cat’s health is checked, keeping litter boxes clean and accessible, and managing stress are key to resolving this behavior.
