Possible Reasons Your Cat Is Urinating In The Kitchen Sink

You’ve just finished having dinner and go to put the dishes in the sink

Only to see your cat jump out of the sink

You go there and a puddle of cat urine in the sink


Now you have to wash the sink and then clean the dishes

What makes it worse?

The smell of cat urine!

It’s the worst smell ever!

Your cat is not doing this out of spite or to get you angry

It’s their way of communicating with you that something is wrong

They can’t literally speaks to us and tell us

So it’s up to us cat parents to figure it out

Lucky for you in this article you’re going to get some idea why your cat is doing this

UTI (Urinary Tract Infection)

This is one of the most common reason why a cat would pee outside the litter box

It’s when your cats urinary tract becomes inflamed which makes urinating painful and increases the urge and frequency to pee

This can cause your cat to pee anywhere in the house because of the urge

This can also happen because your cat associates the litter box with pain

Cats Hate Dirty Litter Boxes

If the litter box is dirty then don’t expect your cat to use it

Think about it

Would we use a washroom that is filthy?

Chances are we won’t

Same goes for your cat

Cats are very clean animals

They spend around 30% of their lives grooming themselves!

So they expect a clean litter box!

Not Enough Litter Boxes

If you have one cat then the general rule is to have one litter box + 1

Basically 2 litter boxes

Some cats like to pee in one and poo in another

If you have two litter boxes your cat has easy access

For example, you can have one litter box in the room downstairs and one upstairs

That way your cat can use the litter box asap when they’re upstairs

Behavior Problem

When a cat is stressed this can cause your cat to pee outside of the litter box

Yes, cats can get stressed very easily

Things like change in routine, a new baby in the family, guests coming over

This can all trigger stress in your cat which causes behavior problems

Unfortunately for you that means your cat is peeing in the sink and not in the litter box


Cats are very territorial

As soon as they think their territory is in danger

They will pee and spray in the house as a way of feeling safe and secure

Your cat may have seen another cat in the garden

Or maybe you bought in another cat which can make your cat feel threatened

Because of this your cat may pee elsewhere other than the litter box

Your Cat Just Loves The Sink

Your cat is not being bad or anything

They just love the sink

Maybe it’s because it looks like the litter box and they prefer to use the sink instead of the litter box

How You Can Stop Your Cat From Peeing In The Sink

Now that we know the possible reasons your cat is peeing in the sink

Let’s look at how you can prevent this from happening

The first thing you should do is

Medical Check Up

If your cat has all of a sudden stopped using the litter box then it’s a sign that something may be wrong

Hopefully your furbaby is okay but when this happens it’s mostly a case of UTI

The best thing to do is get a check up done just to make sure your cat is okay

Cats are very good at hiding away their pain so you won’t see your cat sit in the corner

Very subtle cats are!

But we cat parents now know that litter box avoidance could be a health problem

Hopefully it’s all good and your cat is healthy

Clean The Litter Box

Make sure the litter box is cleaned everyday

You should try to scoop twice a day if that’s possible

If you can’t then once a day

Keep fresh litter for your cat

Just as we want to use a washroom that is clean, same goes for your cat

I understand if you’re working full time and it can be difficult

If that’s the case then I’d recommend investing in a self cleaning litter box

That way you never have to worry about scooping cat litter

Add Another Litter Box

Maybe your cat wants another litter box

You should have 2 already

If you don’t – it’s worth getting an extra one and see if that helps

Location Of Litter Box

Is the litter box next to the dryer or dishwasher?

The noises could scare your cat

Try moving it someplace where it’s quiet and your cat has privacy

Another thing you can do is move the litter box near the sink and see if your cat uses it

Then gradually move it to your desired place

Behavior Problem

Your cat may be stressed out

Something has changed that has caused

Have you changed your cats routine?

New member to the family?

Or maybe other cats are coming into your garden

If there are other cats coming into the area the best thing you can do is just scare them off

Block the view to the garden from your cat until you’re confident the cats won’t come back

Don’t Shout Or Punish Your Cat

Whatever you do, don’t shout or punish your cat

This will just make things worse

If your cat is stressed, shouting will make your kitty more stressed and that means more mess for you to clean up

Patience is key here

Try to have patience and understand that your cat is not doing this to get you angry

I know the smell of cat urine is horrible and you’re tired of cleaning the sink

But this problem will soon pass

How To Get Rid Of Cat Urine Smell From The Sink

Cleaning the cat urine is very important!

Turning the tap on and cleaning it with water won’t do the trick

Don’t use bleach or any disinfectant as this can be really dangerous when mixed with cat urine

What you need is a enzymatic cleaner

This will remove the smell of cat urine completely

Remember – if cat urine is not cleaned thoroughly, your cat will be able to smell it and will come back again and urinate in the sink again!
