When your cat stops using the litter box

Accidents usually mean something needs fixing — here's where to start.

A cat that suddenly avoids the litter box is trying to tell you something. The first step is a vet visit to rule out urinary crystals, bladder infection, arthritis, or constipation — especially if straining or blood is involved.

Next, audit the box itself. Most cats prefer an unscented, clumping litter in a large, uncovered tray. Place it in a quiet spot, scoop at least once a day, and follow the one-box-per-cat-plus-one rule.

Stress is a common trigger. New pets, renovations, or even a changed feeding schedule can push a cat to mark or avoid the box. A pheromone diffuser and a consistent routine often help more than punishment ever will.

If the problem persists, keep a log of when and where accidents happen. Patterns help vets and behaviorists pinpoint whether the cause is medical, environmental, or both.
