What are cats scared of?

We look at what makes our cats afraid, and get the facts behind some oft-reported feline fears including water, their own reflection and cucumbers.

We’ve all heard the phrase ‘scaredy-cat’. But why are felines known for being fearful? While fear is a common emotion in most animals, it may be that we’re particularly aware of it in our cats because their super-sensitive senses of hearing, sight and smell help them react so quickly to being startled – and flee at the first sign of a potential threat! Also, our cats are creatures of habit, who easily become anxious when something takes them out of their usual territory or routine. That said, cats can hide signs of fear and anxiety extremely well, making them hard to pick up on.

Some cats are naturally more fearful due to their genetic make-up, while others – especially larger, stronger breeds such as Maine Coons, Bengals and Turkish Vans – may appear more confident. Socialisation in the first two months of a kitten’s life plays an even bigger role than genetics or breed, however.

Our cats can be scared of all sorts of things around and outside the home, some of which may be obvious (like the neighbour’s dog!) to more unusual fears such as plastic bags, balloons or fans. Here, we look at some widely reported cat fears – and find out what’s actually going on.

Loud noises

Thunder cracks and fireworks can frighten us, so imagine how terrifying they must be to a cat with highly sensitive hearing, and no understanding of storms or Bonfire Night! Don’t miss our top tips for easing a cat’s fears during firework season, including how to gradually desensitise them to the sound.

In the home, cats are often scared of noisy household appliances, especially if they didn’t become accustomed to them as young kittens. Vacuum cleaners, lawnmowers, printers, washing machines and hairdryers are common culprits.

As with fireworks, if your cat has a pronounced noise phobia, it may help to acclimatise them to troubling sounds at a very low volume, and gradually build up their tolerance. This needs to be done very slowly and carefully, however, allowing your cat to leave the situation at any time – read our expert advice on dealing with noise phobia.

Do mirrors scare cats? Well, many cats ignore them completely, while others have a more complicated, fight-or-flight reaction. Like most animals, cats don’t recognise themselves in a mirror. As a result, they may perceive their own reflection as an unknown cat (made all the more baffling because of a lack of the usual scent they’d expect to pick up!). In these instances, your cat may lash out defensively at the mirror, or run away.

There’s not much you can do to prevent a cat experiencing this fear, other than making sure they can come and go freely from rooms containing mirrors – or distracting them with a treat or bit of fuss. Given time, they’re likely to get used to the fact that a strange and scentless cat appears in a certain part of the house. You can expect your cat to have a good look around and behind the mirror, just to make sure the invader isn’t hiding!


Cats evolved in hot, dry climates where they would rarely get wet. Getting drenched makes your pet feel heavy and cold, spoils their careful grooming and dampens their scent signals. No wonder many cats are afraid of water. But it’s a myth that all cats are: Turkish Vans are the breed most famous for enjoying water and swimming; while even some cats that object to being fully immersed in water may play happily with a running tap – Bengals, for example.

It’s generally easy enough for your cat to avoid water – but if you ever need to give them a clean, it’s best to proceed with caution and follow our advice on washing and bathing your cat to minimise their stress levels.

New furniture

When cats rub the furniture or roll on the carpet, they transfer scent markers claiming these things as part of their territory. Change the sofa or rug, and you replace their familiar scent with a strange new smell. That’s why some cats seem nervous or even afraid of your new furnishings. They should overcome this given time, but placing a favourite cushion or blanket on the new items can help ease the transition. You might also like to consider using a pheromone diffuser, to provide a reassuring scent (see below for more on this).

Leaving home

Cats are highly territorial. When you take them to the vet, a cattery or new house, you take them away from their familiar surroundings and scent – something most pets will find unsettling. Be patient with them, provide them with familiar toys or scents to help them feel more comfortable in strange surroundings, and check out our tips on moving your cat into a new home.

Other cats and dogs

To your cat, a pet dog looks and smells like a predator, so it’s only natural they act scared. With careful introductions for the right individuals, some cats and dogs can get on really well, however. Meanwhile, you may love the idea of your cat making friends with another feline, but cats don’t need company and are mostly territorial creatures. As such, they tend to be hostile or fearful when a newcomer enters their territory.

If you’re introducing a new cat to your existing cat(s), it’s best to do so very slowly, introducing their scents – via a blanket or cloth – to each other first, before gradually progressing to controlled glimpses of the other cat and then short, supervised face-to-face meetings, as per our behaviourist-approved advice. The same gradual approach is best if introducing a cat to dogs.


A new person visiting your home smells strange and may act unpredictably in your cat’s eyes, so it’s natural for them to be cautious. Past experiences can play a part, too – for example, being grabbed by a toddler might make a cat frightened of all children.

Overcoming these negative associations takes time and patience. If your cat seems scared of a regular visitor or your new partner, for example, ask the person to sit still and quietly on the floor while they offer your pet some favourite treats. Keep the interactions on your cat’s terms, so they can choose whether to approach the stranger or leave the room, rather than being forcibly petted or picked up.

A few years ago, viral internet videos showed unsuspecting cats freaking out when their owners placed a cucumber behind them while they ate – prompting millions to Google ‘Why are cats scared of cucumbers?’. Some commentators speculated that the cucumber resembled a snake, triggering an innate fear response in the cats. A more likely explanation, however, is that the unsuspecting pets were simply startled by an unfamiliar object suddenly appearing close to them while they were off guard!

Whatever the reason, the cats were clearly discomforted by the experience in the online videos, so be aware that your pet could be upset by the sudden appearance of any unexpected object in their field of view.

Many frightened cats will cower and cringe, body tense, ears flattened with large pupils. More subtle signs of fear in cats include licking their nose, blinking quickly (as opposed to slow blinks when they feel safe), or swallowing in the absence of food.

A cat that is afraid might try to hide somewhere inaccessible, get up to a safe, high vantage point or run away – all of which are cats’ preferred ways of coping with stress and conflict. When this doesn’t work, they may feel the need to show aggressive and confrontational behaviour in an attempt to repel and create more distance between them and the thing they are afraid of. They might hiss, yowl, growl and swipe, back arched and fur raised.

A cat who constantly feels anxious or frightened may show signs of chronic stress, such as pacing, over-grooming or toileting outside their litter tray. This is very bad for the cat’s welfare, so help must be sought.

Prevention is better than cure when it comes to scaredy-cats. Kittens have a short ‘socialisation period’ between about two and seven weeks old. If they have repeated, positive experiences of something at this formative age, they’re likely to readily accept it when they encounter it again in the future.

If you’re raising kittens, gently introduce them to noisy appliances (keeping the appliances quiet at first), different types of people, gentle handling and other friendly, healthy, vaccinated pets. This will help them to be less fearful of these things when they grow up. If your new kitten is coming from a breeder or rescue centre, ask what socialisation techniques they use. Cats Protection has a helpful online sound library that you can use to help socialise your kitten to household sounds.

For older cats, try to imagine the fear from your pet’s perspective and devise solutions. A cosy box on a high shelf could allow your cat to keep a watchful eye on the vacuum cleaner or a visiting dog from a safe height. Cover the box in sound-insulating blankets, and it also becomes a welcome retreat from fireworks or thunder.

A plug-in pheromone diffuser may help some cats feel calmer in fear-inducing circumstances, as can trying desensitisation techniques for common fears. Be sensitive to your cat’s feelings, however, and always allow them to remove themselves from scary situations, as forcing them to confront their fears is only likely to make their anxiety worse.

If you notice signs of fear in your cat regularly – or any sudden change in their behaviour – and can’t pinpoint the source of their anxiety, consult your vet. They will check for underlying health problems, and advise whether it could be helpful to see a qualified animal behaviourist (for example, from the Animal Behaviour & Training Council).
