Litter Box Troubleshooting Checklist

Why is my cat peeing outside the litter box? Usually because of a medical problem, the box set-up, or stress, so the first step is your vet. Then check the set-up against the AAFP/ISFM house-soiling guidelines: two boxes even for one cat, about 1.5 times your cat’s length, open where possible, unscented clumping litter at least 3 cm deep, scooped daily. This one-page checklist starts with the emergency sign every owner should know, then covers eight set-up checks, the medical causes your vet may look for, and an accident log.

Frequently asked questions

Is straining in the litter box an emergency?
It can be. Cornell calls urethral obstruction a true medical emergency: male cats are at greater risk, and death can follow a complete blockage in under 24–48 hours. Repeated trips with little or no urine mean a vet now.
How many litter boxes do I need?
The AAFP/ISFM house-soiling guidelines suggest two boxes for one cat, in separate locations, and at least one per floor. “One per cat plus one” is the older rule of thumb.
Is my cat spraying or peeing?
Spraying usually leaves small amounts on vertical surfaces, with the tail up and twitching, and the cat often still uses the box, according to the AAFP/ISFM guidelines. Neutering greatly reduces it.
Should I punish my cat for accidents?
No. The guidelines warn punishment raises stress and can lead to more spraying, fear and hidden soiling. Work on the cause instead, starting with a vet visit.
