How to stop cats from urinating in the house

Understand why your cat may urinate in your house and how to eliminate cat urine odour for good with Bio one™

Cats urinating inside is a difficult challenge, cat pee has a very strong odour that lingers in your carpets and soft furnishings. Cleaning up every accident thoroughly is the only way to eliminate the smell for good. To stop cats urinating in the house, we need to understand the common reasons why cats pee inside. There are two broad reasons why this behaviour happens; medical and behavioural. 

Medical issues

Like humans and other animals, Cats can easily pick up bladder infections or urinary tract infections. These issues are more common with ageing cats. If your cats begin to urinate in the house unexpectedly, we suggest visiting your vet as soon as possible to get them checked out. 

Behavioural issues

If your vet has ruled out a medical reason for your cat peeing inside, you will likely have a behavioural issue.

Anxiety, stress or change 

Fireworks and other large bangs can cause your cat significant amounts of stress. Always make sure there is a safe place for your cat to go with a clean litter box. If cats become scared by change or stress, they may start to urinate inside, often in corners or other areas, to avoid going outside or to their litter box. If the issue is persistent, your vet can advise the best way to manage your cat’s stress. This could include calming measures and potentially medication.

Litter box issues

Some cats will only urinate in a litter box if it is clean. As soon as it has been used they may look for other places to do their business. This is especially the case if you have several cats, some cats are not happy sharing their toilet with their housemates. Always make sure you have at least one litter box per cat. You should also clean litter trays out on a regular basis to avoid frustration and accidents. 


Some cats, especially intact male cats, will mark their territory, they do this by peeing on varying objects. This is the cat’s way of claiming the space. This is most likely to happen if another animal or cat has been in the vicinity. To prevent this from happening it is important to fully clean any area where another cat or animal has been.
