Cats learn through positive and negative associations . If they have an unpleasant experience in a certain place, they may avoid that place in the future.

If a cat repeatedly experiences pain when going to the toilet – for example due to cystitis, urinary stones or constipation – the following connection could form in its head:

This means that the cat does not think that its illness is causing the pain, but instead "blames" the toilet. To avoid the discomfort, it looks for another place to urinate or defecate.

How can we break this negative association?

A change in toilet behavior can be an indication of health problems. In particular, diseases of the urinary tract or digestive system can cause cats to avoid the litter box.

Possible causes

Urinary tract diseases (cystitis, urinary stones, urinary tract infections)

• These cause pain when urinating. The cat associates the litter box with pain and avoids it.

kidney disease

• Older cats in particular are more likely to suffer from chronic kidney failure. They have to urinate more often and may not be able to get to the litter box in time.

digestive problems (diarrhea or constipation)

• A cat with constipation may avoid the litter box because it is painful to defecate, and if it has diarrhea, it may not be able to reach the litter box in time.

osteoarthritis or limited mobility

• Older cats or cats with joint problems often avoid high litter boxes because getting in is painful.

Cats are sensitive to changes in their environment. Stress can cause them to become unclean.

Typical stress triggers:

New roommates or pets

• A new family member or another cat can disrupt the existing order.

moving or remodeling the apartment

• Even small changes like new furniture or a new location for the litter box can cause stress.

Less attention from the owner

• Cats can feel neglected when you have less time for them. Some cats react by peeing on the sofa or bed.

If your cat is healthy and not stressed, the problem may be with the litter box itself. Cats are picky when it comes to their litter box.

Possible causes

Litter box is not clean enough

• Cats don't like their litter box to be dirty, so they may refuse to use it.

Fake cat litter

• Cats prefer fine, sand-like litter. Coarse-grained or strongly scented litter can be unpleasant.

Too small or closed litter box

• Some cats do not like hooded litter boxes or feel cramped in small litter boxes.

Wrong location

• The litter box should be in a quiet, easily accessible place – not next to food and water.

In households with multiple cats, territorial issues can arise. Some cats feel uncomfortable when they have to share a litter box.

Older cats or cats with joint problems often have difficulty entering high litter boxes.

Sometimes a cat will pee outside the litter box to mark its territory. Unneutered male cats are particularly prone to this.

How do you recognize marking behavior?

• The cat pees in small amounts on walls or furniture.
• She lifts her tail and squirts urine backwards.
• The behavior often occurs near doors, windows or new objects.

Cats don't do their business next to the litter box without a reason. They are sending signals - whether due to pain, stress or dissatisfaction with their litter box. Instead of punishing them, you should find out the cause.

The best approach: Observe closely. Be patient. Offer alternatives. With a little patience and the right adjustments, she will soon be able to use her litter box reliably again. 🐾
