Few cat problems are as frustrating as finding a damp patch on a wall, curtain or sofa. The good news is that spraying usually has a cause, and in most cases it can be reduced or stopped once you find it. This guide explains what spraying is, why cats do it, and what you can try.
Is it spraying or a litter box problem?
Spraying is a form of marking. A cat usually stands, lifts or quivers its tail, and releases a small amount of urine onto a vertical surface such as a wall or door. A cat that squats and leaves a larger puddle, often on a horizontal surface, is more likely to have a litter box or health problem. The fixes differ, so it helps to work out which one you are dealing with.
Why do cats spray?
- Stress or change: a new pet, a new baby, moving house or even new furniture can unsettle a cat.
- Territory: seeing or smelling other cats, especially outdoor cats through a window, can trigger marking.
- Not neutered or spayed: unneutered cats, particularly males, spray far more often.
- Multi-cat tension: competition over food, resting spots or litter boxes.
- Medical causes: urinary problems can look like spraying.
Step 1: Rule out a medical problem
Start with a visit to your veterinarian, especially if the behaviour is sudden or your cat is straining, going to the box often or passing blood. Urinary problems can become serious quickly, so do not skip this step.
Step 2: Clean properly
Cats return to places that still smell of urine. Use an enzymatic cleaner made for pet urine rather than a household cleaner, and avoid products containing ammonia, which smells similar to urine to a cat.
Step 3: Check the basics
- Have the cat neutered or spayed if it has not been already, as your vet can advise on timing.
- Provide one litter box per cat plus one extra, in quiet, easy-to-reach spots, and keep them clean.
- Block your cat’s view of outdoor cats, for example with frosted film on the lower part of a window.
- Keep food, water, scratching posts and resting places separate in multi-cat homes.
Step 4: Reduce stress
Keep routines steady, add climbing spaces and hiding places, and make time for daily play. Some owners try calming pheromone diffusers. The evidence on these is mixed, so treat them as something to try alongside the other steps rather than a cure. Never punish a cat for spraying, as this tends to increase stress and make the problem worse.
What about training programs?
Some owners also look at step-by-step guides written specifically for spraying. Two that are sold online are Cat Spraying No More and Cat Spray Stop (affiliate links). We have not tested either, so we cannot tell you how well they work. If you are considering one, check the refund policy first and compare what each one covers, and remember that no program replaces a vet check if there could be a medical cause.
When to get more help
If spraying continues after the medical and environmental steps above, ask your vet about referral to a qualified feline behaviourist. Stubborn cases are often a mix of causes and may need a tailored plan.
