The Question
“Dear Dr. Paola,
Bella won’t pee in her litter box. She will pee in other places, like on pee
mats or by doors. What can we do?” – Robert
Quick Info about Bella
Hi Robert,
Thank you for reaching out about Bella. When a cat stops using the litter box, the very first step is to make sure there is no medical issue at play. Urinary tract infections, bladder inflammation (feline idiopathic cystitis), crystals, or stones can all cause a cat to avoid the box because they associate it with pain. A veterinary check, including a urinalysis, is the best way to rule this out before assuming it is purely behavioral.
If Bella is medically healthy, then the focus shifts to her environment. Cats are very particular, and things like the type of litter, the cleanliness of the box, its location, or even household stress can influence their choices. Since she is using mats or going near doors, it suggests she wants a different substrate or is marking areas linked to territory. Offering multiple boxes in quiet areas, experimenting with unscented fine-grain litters, and cleaning accidents with an enzymatic cleaner can make a big difference. If stress is part of the picture, synthetic pheromone diffusers and maintaining predictable routines often help cats feel more secure.
Because inappropriate urination has many possible causes, a veterinary evaluation is essential to guide the next steps. Once health concerns are ruled out, addressing Bella’s preferences and stressors usually helps bring her back to consistent litter box use. If you find you need extra support with her behavior at this point, give us a call at Pangovet. We can provide personalized guidance tailored to Bella’s environment and needs.
Best,
Dr. Paola
