Where should I put the litter box?
Pick a quiet, easy-to-reach spot away from her food and water and away from loud appliances or busy walkways. Cats like to feel safe and unambushed while they go, so a corner with a clear line of sight beats a cramped closet or a noisy laundry room. Avoid tucking the only box in a far basement a senior cat has to travel to. In a multi-level home, put a box on each floor. The goal is that reaching a clean box is never inconvenient or stressful.
