why do cats like the smell of bleach

Why do cats like the smell of bleach? – My cat Bob used to go crazy when I used bleach to clean my bathtubs.

He would wait patiently until I had poured bleach all over the tub to deter that gross mildew and then he would go and rub himself all over it!

Thankfully, he never ingested the bleach – which was a good thing too since bleach can be quite toxic to cats.

If your cat loves the smell of bleach and has got you wondering ‘why do cats like the smell of bleach?’, then I have the answer for you.

Let’s find out…

Why Do Cats Like the Smell of Bleach?

why do cats like the smell of bleach

There are several reasons why cats love the smell of bleach.

Although, a lot of these reasons are human speculations, until we smart humans devise a way of knowing exactly ‘what goes on in my cat’s brain?’ these will have to do:

A. Bleach is reminiscent of catnip for cats

Many humans believe that their cats have the same reaction to bleach as they do to catnip. They rub their faces and bodies on bleach and start purring at its scent – just the way they do when there is catnip around.

Catnip and catmint are alluring herbs for cats. Their scent excites cats and many cats literally go crazy for these herbs.

The same thing happens when cats sniff bleach. There is speculation that the same or similar volatile compounds present in catnip and catmint may be also present in bleach and chlorine.

This could be the reason behind ‘why do cats like the smell of bleach?’

B. It is like cat ‘territory marking’

Another reason ‘why do cats like the smell of bleach?’ is that they believe it to be another cat’s urine.

The ammonia smell of chlorine and bleach may be reminiscent of another cat’s urine – again this is just speculation – since we don’t know exactly what a cat may be thinking.

Therefore, if your cat seems to rub itself on bleach or urinates over the area where you recently poured bleach, then, your cat is trying to eliminate the other ‘cat’s scent’ and mark the territory to show that it is his/hers.

C.  It mimics pheromones

The chlorine content of bleach could also mimic cat pheromones. That is the reason why many cats start drooling, rolling, or purring when they smell bleach.

In the next section, I will discuss what cats do when they sniff bleach.

What Do Most Cats Do When They Smell Bleach?

Why do cats like the smell of bleach?

My cat Bob always knew when it was bathroom cleaning day!

He would sit outside the bathroom waiting patiently for me to pour (diluted) bleach over the tub and toilet. The moment I was done, he would purr, roll, and even rub its cheek in it!

Here are a few ‘reactions’ cats have when they smell bleach:

1. Intense happiness

Many cats have an intense experience to bleach- just one sniff and they go nuts!

Some experts believe that bleach triggers a feeling of happiness in cats. That is why they roll, flip, rub, and simply go crazy for it. Some cats also meow and growl at the smell of bleach.

Often, some cats become aggressive or even hyperactive upon sniffing bleach or chlorine. This may be because they think it is another cat’s urine.

Of course, this is usually short-lived happiness!

These ‘happy’ sessions only last for about 10 minutes, after which, most cats calm down. Also, it could take about 1-2 hours for them to become susceptible to the smell of chlorine bleach again.

2. Some cats have no reaction at all

Some experts believe that bleach sensitivity could be hereditary in cats.

This is because, many cats have no reaction to bleach at all. As many as 50% of cats may not even react to bleach.

3. Reaction to bleach may be age-dependent

The reaction to bleach in cats is mostly age-related. Most kittens show no reaction to bleach until after 6 months of age.

Now let us address an important question: is bleach safe to use around cats.

Is Sniffing Bleach Safe for Cats?

Has your cat peed on the carpet? Did you use bleach to clean up the stain? And now your cat is having a ‘happy reaction to bleach?’

Don’t worry, this is quite normal and mostly safe. The keyword here is ‘mostly’.

Most cats do not have any reaction after sniffing bleach, especially when it is diluted.

However, in case you use concentrated chlorine bleach or other cleaning products containing bleach, then the toxic fumes could be irritating to your cat’s skin and eyes – just as they are irritating to human skin and eyes.

Bleach is sodium hypochlorite – a chemical that can irritate the mucosal lining of human and pets’ organs.

That is why you must make sure to dry the cleaned spot thoroughly and only use bleach in super-diluted form.

Don’t worry – a majority of cats don’t ingest bleach – they just roll in it. However, their strong fumes could still irritate your pet’s eyes.

That is why you must only use diluted bleach if you have a cat at home. Better yet, you could switch to natural cleaning products in place of bleach.

In any case, your cat should be okay. Just make sure to ventilate the place well so that the bleach fumes dissipate further.

Keep observing your cat over the next few hours. If it is fine, then there should be no cause for concern. The important thing is to ensure that it is its usual active and cheerful self and eating and drinking normally.

In case your cat has eye irritation or is licking or rubbing its paws, then wash the affected parts with warm water. Do not use soap. Instead, use mild shampoo to wash your cats’ belly, paws, and face if it has rubbed itself in bleach.
