Why does my cat pee next to the litter box?

Cats are considered clean animals, but sometimes it happens that they pee next to the litter box. This can be frustrating, but there's almost always a cause that can be fixed. Find out here why your cat is showing this behavior and what you can do about it.

Common causes of house-soiling in cats

1. Medical problems

Before you assume it's a behavioural problem, you should rule out a health-related cause – especially if nothing has changed in the environment or with the litter box. Urinary tract infections, cystitis or kidney problems can make urinating painful. Stress can also lead to bladder problems.

Solution: A visit to the vet is the first step to rule out an illness as the cause.

2. Stress or changes in the environment

Cats are creatures of habit and react sensitively to change. A move, new housemates or a new cat in the household can make them feel insecure.

Solution: Provide enough places to retreat to and a steady routine, and if needed use calming pheromones to give your cat a sense of security.

3. Dirty or unsuitable litter box

Cats are very picky when it comes to their loo. Possible problems:

• The litter box isn't cleaned often enough.
• The litter isn't the right one.
• The location is poorly chosen (too noisy, too hidden or hard to reach).

Solution:

• Clean the litter box daily and change the litter regularly.
• Try out different types of litter and watch which one your cat prefers.
• Put the litter box in a quiet but accessible spot.

4. Too few or the wrong litter boxes

The rule of thumb is: one litter box per cat, plus one extra. The type of box matters too: some cats don't like covered boxes, others need plenty of space.

Solution:

• Provide at least one litter box per cat.
• Test different models (open, covered, large, small).
• A spacious litter box like the Steeloo can help if your cat feels uncomfortable in conventional models.

5. Marking behaviour

Unneutered males in particular, but also female cats, can stake out their territory by marking with urine.

Solution: If your cat hasn't been neutered yet, this can solve the problem. For cats that are already neutered, more play and activity can help.

What to do if your cat still isn't using the litter box?

• Use enzymatic cleaners to remove odours completely.
• Praise your cat when it uses the litter box.
• New housemates, new litter boxes or a different litter should be introduced gradually.
  

With patience and the right measures, you can often solve the problem and help your cat become clean again.
