11 Surprising Smells That Cats Hate

Cats have a fantastic sense of smell with over 45-80 million olfactory receptors in their nose to compensate for the lack of taste buds.

Humans have only 5 million, so we can smell only a fraction of what our cats can.

Moreover, cats have got a Jacobson’s organ in the roof of the mouth that allows them to deep-analyze any smell. T

hat’s why your cat remains with an open mouth when they catch an interesting scent.

Thanks to these superb senses, it’s no wonder that cats can’t stand certain aromas and run in the opposite direction.

#1 Citrus

Citrus fruits, such as orange, lime, lemons, and grapefruits, have a peculiar aroma that appeals to most humans.

We connect the scent with something delicious to eat.

However, cats find it repelling because it’s too strong for their delicate noses.

They might also detect aromas that our noses aren’t capable of processing.

The cat repellent abilities of citrus are well known.

That’s why many owners often advise that you place orange peels to keep the cat off the counter or place the peels around plants you wish to protect.

But citrus fruits are also toxic for cats and dogs and cause stomach discomfort, vomiting, and diarrhea.

Fortunately, you’ll rarely find a cat that likes to chew on orange peels.

#2 Mint

Who doesn’t like the refreshing smell of mint or eucalyptus?

While mint and eucalyptus have health benefits for humans, cats hate mint aromas.

That’s a little strange since mint and catnip are from the same family.

But while many cats get high on catnip, others stay as far away from mint as possible.

Other plants with minty scent, such as wintergreen and menthol, are also likely to repel cats.

The same goes for eucalyptus, which it’s often used in eco-friendly products to repel cats.

Still, keep any mint-related plants out of your cat’s reach to be on the safe side.

Mint and eucalyptus are toxic to cats when ingested.

#3 Lavender (Lavandula)

With its pleasant aroma and distinctive purple flower, lavender is a common garden plant found in many gardens.

People often use it in aromatherapy for its calming effect and stress-reducing properties.

While lavender has a pleasant scent for people, the aroma is too pungent for our cat’s fantastic olfactory receptors.

Many cats hate it and stay away from lavender plants.

But I’ve also seen cats sleep in lavender bushes with no ill effects.

Moreover, the ASPCA reports that lavender and lavender oil are toxic for cats and dogs.

Don’t try to use lavender to calm down your anxious cat, or you can poison your pet by accident.

Ask your vet about anti-anxiety products suitable for cats.

#4  Geranium

Geranium is another common plant whole smell cats hate.

That’s not surprising since people say geranium has a citrus-like scent or a lemony-green aroma, and we know how cats feel about citrus.

While people often plant a geranium in the garden to keep cats away, you should know that the plant is toxic to pets.

It can cause skin irritation and vomiting if your cat chews on the leaves.

#5 Common Herbs

Rosemary and thyme are among the most common herbs in cooking and give food a mouth-watering taste.

Cats don’t seem to mind these herbs when they steal food from our plates.

But surprisingly, many cats hate the smell of rosemary and thyme.

That’s why people often recommend planting rosemary around your garden if you wish to keep cats away.

Fortunately, both thyme and rosemary aren’t among the toxic plants for cats.

Some cat food brands also use rosemary extract as a preservative. That could explain why your cat turns up their nose at the food.

Besides rosemary and thyme, you can add rue to the list of smells that cats hate.

Rue has a bitter/acrid scent that’s too offensive for your cat’s nose.

#6 Spicy Aromas

While many people love the spicy aroma of pepper, curry, and cinnamon, cats don’t.

Just imagine how intensive the smell must be for your cat’s senses!

As a whole, spicy or heavily seasoned food isn’t good for cats because it upsets their stomach.

That’s probably one of the reasons why cats are wary of anything that gives off such a pungent scent.

Moreover, some spicy peppers can be toxic if ingested and cause extreme stomach distress.

So, don’t sprinkle pepper flakes on the ground because your cat can swallow them when they groom.

Cinnamon, on the other hand, is non-toxic to cats, as stated by the ASPCA.

Still, many felines strongly dislike the hot, spicy cinnamon scent and don’t want anything to do with it. So, your cinnamon cookies should be safe from grabby paws!

#7 Pine/Cedar

How could cats hate pine when they have such a fascination with Christmas trees?

Well, maybe cats like to destroy Christmas trees because they hate the pine smell so much.

Joke aside, a lot of cats don’t like pine or cedar, even though manufacturers used it to produce natural cat litter. 

It’s not a universally hated scent, but many cats are put off by the smell’s intensity and prefer unscented litter.

Fortunately, there are other ways to eliminate litter box odors.  

#8 Bananas

Who could hate the sweet smell of bananas?

As it turns out, some cats really hate bananas and would turn their backs on you when you let them smell it.

I suspect it has to do with chemicals used on the peel to preserve the bananas.

We might not be able to detect these faint traces of chemicals, but it won’t be a problem for your cat’s olfactory receptors.

In general, bananas aren’t harmful or toxic to cats. Some cats might even enjoy them as an occasional treat.

But be careful not to spoil your cat too much since bananas are high in sugar.

#9 Coleus Canina

You might know Coleus Canina as a scaredy-cat plant, but do you know why people have named it so?

Coleus Canina has a smell that resembles a skunk and is considered a cat/dog repellent.

After all, who doesn’t hate that awful skunk smell that lingers for days?

The plant releases the unpleasant scent when someone brushes against it or breaks leaves/stems. As such, most cats don’t make the mistake of going twice near it.

#10 Dirty Litter Box

No one likes a dirty bathroom, especially clean creatures, such as cats.

Your cat will do their business anywhere else but in an unclean litter box, so keeping the litter box clean is a necessity.

Moreover, if you have multiple cats, they might hate the smell of the other cat’s waste, especially if the cats don’t like each other.

#11 Essential Oils

Essential oils have risen in popularity in recent years, and we often used them for various ailments.

However, cats hate the smell of essential oils because it’s too intensive and overpowering.

Moreover, most essential oils aren’t safe for cats because they lack the necessary liver enzymes to break them down.

As such, one possible side effect is liver failure.

These oils can also be absorbed through the skin or ingested while grooming and lead to ataxia, drooling, vomiting, and respiratory distress, among few.

Cats who inhale essential oils might develop watery eyes and noses or have trouble breathing.

As you can see, there’s a good reason why cats hate certain smells and don’t dare go near them.

The pungent aroma prevents the cats from chewing on plants that could kill your pet if they consume enough or get exposed to dangerous chemicals.

If a scent is strong for you, it’s probably unbearable for your cat.

Keep that in mind, when you light candles and don’t use essential oils around your cat.
