How to Cat-Proof Your Balcony: Catios, Enclosures and More!

You might think that your cat is safe on your balcony. After all, cats always land on their feet and they have nine lives! Unfortunately, neither of these things are entirely true. In fact, cats can be injured or even killed by falling from great heights.

This is known as high rise syndrome and can have serious consequences for your pet. If you and your cat live in a property that is higher than two stories, then you need to think about cat-proofing your balcony.

Unfortunately, falls aren’t the only problem. If you will be leaving your cat on your balcony, then you will need to give them a safe environment (beyond just a railing). That includes somewhere to shelter from the weather and also ensuring all plants nearby are safe. There are a few options available, including buying a pre-made cat cage like the Prevue Premium Cat Home or building your own ‘Catio’.

Cat High Rise Syndrome

Cats have great survival instincts. They won’t deliberately jump from a height that would cause them injury – that’s why you sometimes find them getting stuck in trees.

However they are also incredibly focused on their prey, and even the most graceful feline can sometimes be clumsy. It’s possible that a cat could be so focused on a bird or insect, that it would leap from a balcony. Or it might jump to the top of the railing, only to fall during a particularly intense grooming session.

Sometimes, even trained indoor cats can find that open window and put themselves at undo risk.

Once cats have reached 6-7 weeks old, they’ve perfected the ‘cat righting instinct’ which means they usually fall on their feet. They can do this because of their unusually flexible spines, however, it doesn’t mean that they can fall from any height and remain uninjured. In fact, pets with injuries to their legs, pelvises, jaws, and lungs are common at the vet. They can also die on impact.

If your cat does fall, even from a short height, and you have any concerns it is worth taking them to a vet. Prompt medical attention will give your cat the best chance of survival.

Catios: The Ultimate Cat Enclosure Solution for Apartment Dwellers

When it comes to providing a safe balcony space for your pet, you have two options.

You can either buy a pre-made cat cage / cat patio or ‘catio’, or you can build your own. While the former is the most expensive option, you do have the security of knowing it has been built by professionals. If you choose to make your own, not only can you save money, but you can also design your catio to suit your needs.

If you rent, then you will need to ensure that your landlord is happy with you making modifications to the property. If you own your property, then it’s worth checking any resident’s association rules to avoid causing a problem.

If you wanted a bespoke catio made for you, then you could make contact with a local cat owners club to see if any local workmen have experience in making them. You could also buy a pre-made unit and install it on your patio. Also called cat cages, or pet runs, these have variable amounts of security so may not be suitable for leaving your cat unattended.

Build A Catio Yourself


To give you an idea of how you could build your own Catio, watch this video from Addicted to Happy on YouTube where they cat-proofed their balcony for under $30.

As you will see, there are two areas of concern. The first is the space between the railings if your balcony has them. You need to make sure that your cat can’t squeeze between them, either by blocking them with solid board or adding mesh or wire. You will also need to think about how to prevent a fall from the balcony railings. Netting or wire are good options here as they won’t obstruct your view but they will keep your pets from falling. For more information, have a look at this article from Wikihow.

Alternatives to a Catio

If you’d still like your cat to get some fresh air, but you don’t want to give over the balcony to them full-time then there are still some ways to safely do this. Rather than having a large construction, you could choose a smaller pen such as a dog cage (just don’t mention the ‘D’ word to your fur baby) or a fold-away cat pen option which you could remove when your pet isn’t out with you.

You can also train your cat to use a harness. While cat’s don’t take naturally to the leash, with a little patience and some training, they will be comfortable to explore while you keep hold to ensure they can’t have an accident.

Please note: With either of these options you would need to stay with your pet on the balcony at all times.

Other Things to Consider

Unfortunately, falling isn’t the only problem that your pet might encounter when on your balcony. Here are a few more concerns that you should think about before you leave your pet out for any length of time.

Weather Conditions

You will need to make sure that your pet has somewhere to go, no matter what the weather. Balconies are often sun traps, so ensure that there is a shady spot to prevent your cat getting too hot. You’ll also want to ensure that your fur baby always has access to fresh water in case he or she gets thirsty. Somewhere to cuddle up if it gets chilly is also a good idea, and making sure that your cat can retreat to somewhere dry in the event of rain.


Even if they do have the outdoor world to look out on, cats can still get bored. A scratching post is often popular, and regular changes of toys should keep your cat amused, even if you have to leave them for a couple of hours. Look for toys that combine treats to help them hone their hunting instincts and keep them happy on two fronts.

Cat Friendly Plants for Balcony

Unfortunately, some of the plants that we most commonly use to decorate our outdoor spaces are also toxic to cats. The last thing you want is for your pet to accidentally poison itself by nibbling on your floral displays. Chrysanthemums, Cyclamen, English Ivy, Daffodils and Tulips and more can all cause a problem. A complete list can be found here.

Symptoms of poisoning in cats include breathlessness, vomiting, diarrhea, and drooling or excessive swallowing. If in any doubt, consult your vet.

You could also think about planting a balcony garden for your cat’s entertainment. Plant a pot up with cat grass, catmint and catnip to please your pet. Add butterfly attracting plants like lavender and Thyme and not only will your balcony smell great, but it will have an extra source of entertainment for your kitty.

FAQ: Frequently Asked Questions About Cats and Balcony’s

Is it safe to let my cat on the balcony?

A cat is never completely safe on an un-enclosed balcony. While your cat may go years without any issues, all it takes is one clumsy moment, particularly if you are above the second story.

Do cats know not to jump off of balconies?

Yes, cats have a natural aversion to jumping from heights which they cannot accurately judge or which might injure them. This doesn’t mean that accidents don’t happen. Even though most cats can “land on their feet”, the laws of gravity are still in effect. A fall from a any height can still injure or kill a cat.

How high can cats fall?

It’s possible that a cat can fall multiple stories and still survive (albeit with injuries). According to this study in the Journal of American Veterinary Medical Association, 90% of cats survived falling 5.5 stories at a terminal volocity of 60 MPH (132 accident report cases). This does NOT mean that cats are safe by default. Key variables include the time to manuver (ironically, longer falls give cats more time to spread and anticipate), cross winds, landing area, etc…

High Living, not High Rise

Although balconies can be a problem for cats, there’s no reason why even high-rise dwellers can’t let their cats enjoy the great outdoors. Whether you want to go the whole hog and cat-proof the entire balcony or just make sure your kitty is safe when you chill out with a glass of wine in the evening, we hope that this article shows that there are options for everyone!
