Cat Pees in The Sink – How To Prevent It?

Cat Pees in The Sink-How To Prevent It

In the words of Charles Dicken, “What greater gift than the love of a cat?”

But what if that love comes in the form of a cat peeing in sink?

So much for the loving right ?


A cat peeing in sink could be a sign of many things. Also, a urinary tract infection can cause this weird behavior. Other cats would pee in the sink if their litter box is filthy or they are just avoiding it. Better yet, cat peeing in sink could be out of behavioral problems or he loves how your sink looks.


Before you give your cat up for adoption, let us first explain to you why the furbaby is peeing on your sink.

Cats are masters of decorum and peeing inside a sink is not their style.

So, when you see your kitty doing it, there is an underlying problem which we will explore in this article.


Why does my cat pee in the sink?

Your cat is peeing in the sink because of these reasons;

  • A filthy litter-box
  • A urinary tract infection
  • A preference for your sink
  • Age
  • Behavioral issues


Filthy litter box

Cats are naturally clean.

This is why they spend most of their day grooming themselves from head to paw.


Even though they risk swallowing a hairball or two, it is worth it to them.


When your cat starts peeing outside the litter box, chances are the litter box is dirty.

Litter boxes fill up quickly without notice.

Perhaps when a strong stink comes from the litter tray is when we are compelled to clean it.


But a cat will catch that awful stink long before you.

And no cat in the world will do its business in a stinky box.

Your kitchen or bathroom sink look clean and hidden enough for your cat to take a leak in.

A Urinary Tract Infection

Yes, cats do get UTIs as well.

And while humans complain of a burning or itchy sensation when peeing, cats will show symptoms by peeing in odd places.


The habit is motivated by a cat not understanding the discomfort they are having.

If peeing in the litter box causes an itch, a cat will look for other places to relieve themselves.


They may choose a sink or bathtub because they believe these places won’t cause the same itch.


As a pet parent, taking your cat to a vet will help diagnose a UTI as the cause of your cat peeing in sink.

He prefers your sink

Perhaps your cat pees in the sink because he likes it there.


Let’s face it, if you have a chance to take a leak at a motel vs a Ritz Carlton bathroom, chances are you will take door number two.

Cats understand this comfort too, which is why your sink is a fancy upgrade.

Also, maybe the cat pees in the sink because something draws him there.

For instance, the smell of bleached sinks is known to drive cats crazy.

And a stoned cat is bound to do un-catlike stuff like peeing where they see convenient (now why does that sound familiar?).



Sadly, some cats lose their bearings as they grow older.

Dementia kicks in and they start forgetting stuff, including their house training.


An elderly cat patched high up on your sink may not have the energy to make the journey to the litter box.

As a result, peeing in the sink becomes the only option.


It could also be that your aging cat is now mistaking the sink or your tub as his litter box.



You can teach a cat to do anything that it wants to do


Anxiety in cats can cause odd symptoms like peeing on sinks, tubs, even carpets.

Some cats, out of anxiety, may develop a humping behavior.


Feline anxiety comes with the following symptoms too;

  • Mood swings
  • Isolation
  • Loss of appetite
  • Weight loss
  • Aggressive behavior
  • Cat meowing a lot

If left unchecked, peeing can easily escalate to pooping in your tub.

A visit to the vet will help determine if your cat has underlying psychological issues.
