First, rule out a medical issue
A sudden change in litter-box habits can be caused by urinary, digestive or mobility problems. Straining to urinate, repeated trips with little output, crying or blood in urine can be urgent, especially in male cats. Contact a veterinarian promptly rather than treating the issue as a training problem.
Keep the box clean and accessible
Scoop at least daily and wash the tray regularly with mild, unscented products. Place boxes in quiet, easy-to-reach locations away from noisy appliances and food bowls. Older cats may benefit from a box with a lower entry.
Choose a box and litter your cat accepts
Many cats prefer a roomy, uncovered box and unscented litter, but preferences vary. If changing litter, do it gradually and keep the previous option available during the transition.
Plan for multi-cat homes
A common guideline is one litter box per cat plus one extra, placed in separate locations where possible. This reduces competition and makes it easier for each cat to access a box without being cornered.
Reduce stress around the litter area
Changes at home, unfamiliar animals or conflict between cats may affect toileting. Provide hiding places, vertical space and separate resources. Clean accidents with an enzymatic cleaner and avoid punishment, which can increase anxiety.
Final thoughts
A clean, accessible litter setup helps many cats, but persistent or sudden changes should be discussed with a veterinarian. Note when and where incidents occur to help identify patterns.
