Why does my cat pee on the rug? Are they trying to tell me something?

ADELAIDE: As cat researchers, one of the most common complaints we hear is: My cat is a jerk! Whenever I do something he doesn’t like, he pees on my bed or the rug.

Often this complaint is based on an assumption the cat is seeking revenge or trying to send a message, The Godfather-style.

Unfortunately, a rhetoric has developed that cats are manipulative, vengeful, uncaring or even psychotic. This rhetoric means when cats do something we don’t like, it’s easy to reach for the idea they did it deliberately to hurt or annoy us.

But cats don’t behave the way humans do and their motives are not the same. They aren’t trying to irritate or punish us. So let’s forget the human rhetoric and delve into five reasons your cat might be peeing on your rug, bed or clothes.

1. It could be a medical issue First, ask yourself: are they sick? Many illnesses or injuries – including urinary tract infections, cystitis, diabetes and chronic pain – can cause a cat to have unusual urination behaviour.

Feline idiopathic cystitis occurs in approximately 2-4 per cent of cats worldwide. The exact causes are not known, although having an anxious or stressed cat increases the risk.

It’s often difficult to tell when a cat is sick. They are incredibly adept at hiding pain.

One clue is cats experiencing discomfort will want to pee somewhere they feel comfortable, often a place they associate with safety – such as your bed, your clothes or the rug.

One reason they may feel comfortable there is because it smells like you, someone they associate with positive feelings.

So if your cat pees somewhere odd, your first instinct should be to wonder if it’s time to contact your vet.

2. It could be short-term stress Has something changed in your household lately? Are you renovating? Are there loud noises? Did a new cat move in next door? Did your friend bring their dog to visit? Situations like these could lead to your cat feeling stressed and peeing in an unexpected place.

Log the days your cat pees somewhere unusual and see if a pattern emerges.

If it correlates with something in particular – such as a friend visiting with their dog – try to adapt the house set-up to make your cat more comfortable.

For instance, keep the dog outside or put your cat in your room with their food, water and a litter tray.

Think about how to make your cat more comfortable (or remove the stressor itself).

3. It could be chronic stress Unlike a short-term stressor, chronic stress is an ongoing issue that can’t simply be stopped or removed.

This could be an ongoing stress from living in a multi-cat household or with a dog, or it could from a condition such as anxiety.

While chronic stress can be trickier to handle, it’s important to identify it and seek help.

Ongoing stress can lead to serious health issues such as cystitis, which can cause a urinary blockage and be life threatening. If your cat visits the litter tray and is straining without any result, this is an emergency. They need to see a vet as soon as possible.

Keep a short daily log and try to identify areas that may be causing ongoing stress for your cat.

Adjust the environment to limit these stressors and if needed, seek a veterinary behaviourist’s advice about treating potential anxiety in your cat.

And if you are very stressed, this might make your cat feel stressed. Sometimes you both need to take a deep breath! 4. It could be the litter Your cat’s “accidents” may be as simple as them not liking the substrate, tray or positioning of the litter they are given.

Cats want to feel comfortable and safe when they toilet. So they may not want to use it if: . the substrate you’re using hurts their paws or is too deep and makes them slide around . the tray is too small or too covered or . the litter is positioned somewhere that is disturbed easily.

Each cat is an individual; what works for one may not work for another. That said, here are some general rules for providing a pleasant litter experience for your cat: . provide one litter tray per cat plus an extra one for the household . litter depth should be enough to cover the bottom of the tray well but not so much that the cat’s weight makes them slip down into it . go for unscented litter (cats are very sensitive to smells) . place the tray in an area that has privacy and is away from any potential stressors such as children, dogs or loud noises . if possible, place the trays around the house in appropriate areas so your cat always has easy access when needed . scoop regularly and keep the tray clean.

5. It could because your cat is a jerk Just kidding. This is never the reason.
