Litter box problems are frustrating — and always have a cause. Here's how to figure out why and fix it.
Rule out medical issues first
Sudden litter box avoidance is often medical — urinary tract infections, crystals, or arthritis making the box hard to enter. Any sudden change warrants a vet visit, especially if you see straining or blood.

Box and litter problems
Cats are particular. A dirty box, the wrong litter, a covered box they dislike, or too few boxes all cause avoidance. Provide one box per cat plus one extra, scoop daily, and try unscented clumping litter.
Location and stress
Boxes should be in quiet, accessible, low-traffic spots — away from food and noisy appliances. Stress from new pets, moves, or routine changes can also trigger accidents. Pheromone diffusers help anxious cats settle.
Clean accidents thoroughly
Use an enzymatic cleaner on accident spots — regular cleaners leave scent that draws repeat marking. Never punish your cat; it increases stress and makes the problem worse.
