The best outdoor runs and enclosures for cats

Australians have one of the highest rates of pet ownership in the developed world. A national survey found that in 2019, 27% of Australian households owned a cat, with the estimated cat population of 3.8 million cats. Our cats bring us many benefits such as companionship, affection and enjoyment. They also bring responsibilities and obligations to ensure that we give them the care that they need for a healthy life.


Responsible cat ownership

Responsible cat ownership requires owners to consider not only the needs of their pets, but also the social environmental issues associated with keeping a pet. Increasingly, cat owners are becoming aware of the many dangers that outdoor roaming cats encounter. Cats who roam freely tend to have significantly shorter lifespans – by almost 10 years according to the Cat Protection Society – as a result of exposure to traffic, attacks from other animals, untreated health conditions, diseases and injuries, and weather extremes.

Another consideration is that cats are hunters by nature, and outdoor cats pose a tremendous threat to native wildlife; even cats that are well-fed. For this reason, some councils have introduced by-laws to enforce night-time curfews or even complete confinement (contact your local council to find out if these apply in your area).

There is a growing acceptance by cat owners of the benefits and need to contain cats, resulting increasing numbers of cats that are kept solely indoors. Most cats adapt well to living indoors, especially if this is undertaken from an early age. However, adult cats that are used to roaming freely outdoors may have some difficulty adjusting to this dramatic change in their lifestyle. If this is true for your cat, we recommend keeping him inside overnight, then gradually increasing the time you keep him in by day.


Giving indoor cats room to roam

Cats need physical and mental stimulation in order to thrive. Outdoor access and exercise are extraordinarily effective with feline behavioural problems, so it’s essential that indoor-only cats have plenty of opportunity to obtain these. Giving indoor cats exposure to the outdoors in a safe and contained environment is the ideal solution, and not as difficult as you may think. One very effective way is to follow the growing trend of providing a cat run and/or enclosure in your outdoor living space, where your cat can enjoy the fresh air, sunshine, and sights and sounds of the outside world, and also have room to move and exercise.

cat outdoor enclosure

Whether you have a garden, backyard, veranda or balcony, there are options for providing a safe outdoor area for your cat. The most common methods are to cat-proof your fence or to use netting to enclose all or part of your outdoor space.

Even if you have no outdoor access and/or a limited budget, there are things you can do to make the outside world accessible for your cat, including:

  • Adapting or cat-proofing your existing fencing
  • Installing cat-proof netting or screens around all or part of your garden, porch, balcony , side alley or window frames
  • Purchasing or constructing a “catio”, or cat enclosure, with or without a cat run or tunnel to connect it to your house
    Building an enclosed, tunnel-like cat run along a fence, around the side of the house or even across the roof
  • A combination of the above, depending on the available area and what best suits your own and your cat’s requirements; for e.g. a garden enclosure can be combined with a runway along the fence that leads to a cat flap into the house.

If you find yourself confused about which type of cat run or enclosure is best suited to both you and your cat, here are a few things to consider:

  • Do you have an outdoor area that can be enclosed, such as a garden, backyard, courtyard, porch, balcony, or side-of-house passage?
  • How much space is available for an enclosure?
  • What sort of activities does your cat enjoy (e.g. climbing, playing, or snoozing in the sun?)
  • Do you want the enclosure to have access to your home via a window or cat door?
  • Do you need your enclosure to be portable?
  • Would you prefer to design and/or assemble your enclosure yourself?
  • What is your budget?
  • Do you own or rent your home? (If you are renting, you will need the permission of the owner to make any modifications to the property)
  • How high is your fence or wall? Does it keep you cat contained to your property?

Cat-proof fencing

A regular fence may not prevent your cat from escaping or other animals from entering your yard. Cat-proofing your existing fencing is one of the simplest ways to ensure that your cat cannot leave your property and that other cats can’t get in. Cat-proof fencing also has the advantage of providing your cat secure access to the entire outdoor area around which it is installed. According to Animal Welfare Victoria, if you have a small yard then this may be a better and cheaper alternative to building a cat enclosure. An ideal position for cat proof fencing is the narrow corridor between the house and a fence that can be closed off at each end by gates.

To cat-proof your fencing, you need to ensure that your cat cannot get over the top of it, either by raising it or installing an escape barrier on top. You will also need to seal any gaps or holes in or under the fence, make sure that it has no escape routes such as overhanging trees or other climbable structures or jumping points, and that the garden itself is safe by making toxic plants, garden chemicals and other dangerous objects inaccessible. Cats can be very resourceful, so even with these precautions, it is advisable to monitor your cat when you allow him outside in your yard.

Several cat-proof fence suppliers and installers are available in Australia and there are also many affordable DIY options using items such as shelf brackets and chicken wire, nylon mesh or even chain link fencing to create a suitable overhang on top of the fence (see How to build a cat proof fence using a net barrier). In most local government areas in Australia, fence extensions and raising the height of your fence is legal unless extending beyond your property boundaries (i.e. any protrusions are on your side of the fence). However, it is recommended that you check with your local council, and gain your neighbours approval, and the owner’s if you are renting, before making any modifications.

Oscillot® sells an unobtrusive fence-top cat containment device comprised of a series of paddles that are installed consecutively, one after another, for the length of the fence line (or area to be cat-proofed). When the cat tries to jump and scale the fence, he places a paw on the paddle, which then spins; he cannot get traction and falls safely back to the ground. Available in DIY Kits for self-installation and suitable for most fence types of at least 1.80 metres in height, this system is endorsed by the Animal Welfare League of Australia and the Animal Welfare League of Queensland.

Cat netting)

Another popular option is using netting to create a cat enclosure and/or cat run to prevent your cat from escaping, whilst stopping others from getting in. Netting is an ideal material to use for a cat enclosure, as it is very versatile and easy to work with. The quality of the netting is important – cheap netting can sag and perish, while high quality netting is strong and long lasting; look for one that is UV tested and warrantied for at least 10 years.

Common cat run options using netting include:

  • Veranda or balcony enclosures
  • Side alley enclosures
  • Stand-alone freestanding cat enclosures
  • Attached or freestanding cat runs
  • Fence line perimeter netting

Cat netting is a simple yet highly effective solution when installed from floor to rooftop. For instance, a veranda or balcony can be fully or partially enclosed with netting to create a safe outdoor haven for your cat. If your house has a side alley, it can also be transformed into a net-enclosed cat playground, particularly if it can be accessed directly via a door, window or cat flap.

There are several Australian companies that will custom design and manufacture a netted enclosure to suit your exact requirements and provide professional installation, but keep in mind that this can be a costly exercise. For considerably less expense, you can purchase ready-to-assemble kits or you can go completely DIY and purchase the individual components required to do the entire construction and assembly yourself.

Pop-up tunnels and tents are the simplest, cheapest and most portable options for an outdoor cat enclosure and run. They can be used indoors as well as outdoors, taken to the park or on camping trips, and packed away quickly and easily if necessary.

We found this basic tent-tunnel combo on Amazon. Additional tunnels can be added to extend the length of the run.

DIY Cat Runs

If you are creative and handy with the tools, a DIY enclosure or run can often be the ideal – and cheapest – solution. You have the option to customise to your requirements and come up with your own design, search the web for one of the many freely downloadable plans, or seek advice from your local hardware store.

When determining the size of the enclosure, the NSW cat protection society recommends that each cat requires a metre to themselves. So, for one cat, your enclosure should be at least 1m high x 1m wide x 1m long, while for two cats it should be at least 1m x 1m x 2m, and so on. Ideally, make it as big as you can for your cat to enjoy the outdoors, with enough space and equipment for him to climb, play and snooze in the sun or shade.

CatNets sells cat netting by the metre and in bulk rolls, as well as a range of DIY installation accessories (zippers, clips and fasteners) and DIY kits direct to the public. Their netting is strong, pre-stretched to avoid sagging, UV treated and designed to last in the harsh Australian outdoors. and, outdoor climbing equipment and cat doors. See their FREE DIY GUIDE here.

There are many great examples of DIY cat enclosures and tunnels on the internet; see, for example, this extensive construction from Cuckoo4design, comprising access via a cat door from the living room window into a window box that leads to a lengthy tunnel along the fence, which leads to a spacious, multi-level cat enclosure at the back of the garden.

Apartment living

Indoor cats can live happily and successfully in apartments. If you have a balcony, netting can easily and inexpensively transform it into a safe space where your cat can enjoy the outdoors. Transparent or low-visibility netting is available to comply with building regulations and to keep balconies looking neat.

Once your balcony is safely enclosed, add some items of feline interest to transform it into a special place for your cat. Maximise the use of vertical space by installing a series of perches at different heights, which will provide your cat with elevated views over the neighbourhood and can be used for climbing and even napping. A special cat bed can be placed on a perch or in a sunny, sheltered corner of the balcony, while toys can be strategically placed to move or flutter in the breeze. Potted plants such as cat grass, catnip or cat mint, will add to the appeal for your cat.

If you don’t have a balcony, a mesh-enclosed fixture attached to the outside of a window frame (similarly to an air conditioning unit) can provide a spot to enjoy the fresh air and observe the outside world. This can contain a comfy resting spot and some cat-friendly items. If this type of addition isn’t feasible, you can install a comfy, padded perch or shelf indoors, near a sunny window. You can install cat netting or fly screens over your windows so they can be open but cat proof.

Creating a stimulating indoor environment

Cats that have previously had lots of outdoor access will need to be provided with enough stimulation indoors to prevent them from becoming bored and destructive. An enriching environment is the key to keeping your cat happy indoors; even more so if you are unable to set up a safe outdoor space for him. Indoor environmental enrichment will allow your cat opportunities to express normal behaviours such as scratching, playing, and hiding. Multi-level climbing and look-out perches, scratch posts. interactive toys, and indoor runs in which to move about are good options.

Try to simulate the outdoor environment within your indoor setting as much as possible. For example, you can invest in pot plants containing feline-friendly plants that cats like to nibble on when outdoors, such as cat grass, catnip or cat mint. Avoid plants that are toxic to cats such as lilies. For more information, see the Cat Protection Society’s factsheet on Cat-friendly Flowers.

Hunting is another outdoor activity that cats like to engage in; even if they don’t catch any prey, they are often pouncing on leaves or lizards. You can replicate this somewhat by hiding food or by providing it in food-releasing toys. Of course, cats love to climb trees and sit somewhere high up where they can watch the world from above, so allow your cat access to windowsills, ledges and shelves, preferably where they can see out as well as in.

If space permits, portable cat runs and smaller catios can be set up indoors, to add variety and create a secluded space. However, some cat owners have gone above and beyond to create permanent indoor cat runs in their homes. For example, this owner installed crown moulding, with a carpeted top, around the living and family rooms approximately 30cm below the ceiling, with two sets of picture ledges up the wall as steps:

While this owner has provided her cat with floating steps leading up to a sunny perch from which to observe the great outdoors – another fantastic way to keep an indoor cat content.

Other options for safe outdoor activity

Walking your cat

It is possible to train your cat to spend time outdoors using a harness and lead. Cat harnesses are available for cats of all sizes; they fit around the cat’s body and attach to a lead that lets you walk your cat safely outside. However, many cats are simply not suited to lead walking, and this may be a good option only for particularly relaxed and outgoing felines.

If you live in a peaceful neighbourhood in which you can walk without encountering loose dogs, you may have more success, particularly if you start while your cat is young.


Supervised outdoor time

You might like to restrict your cat’s outdoor access to supervised time in the garden or courtyard. This will entail keeping a close eye on your cat and stopping him from climbing the fence and escaping your property. Gardens can be made cat-proof through clever use of fencing or netting, but any overhanging tree branches or jumping points may provide a swift escape route. Some cats can be harnessed and secured to a stationary object to enjoy the outdoors while you are relaxing or gardening nearby but be sure to never leave your cat alone while he is tethered.

Calico cat walking with woman

If your cat is inclined to wandering off, it can be helpful to plant a border around the area where you want your cat to spend outdoor time. Citrus smelling plants and herbs are great for this purpose – they are non-toxic, and most cats do not like the smell of citrus and will not want to brush past them to escape. It is possible to design an enclosed garden that is wildlife friendly as well as providing safe and interesting space for your cat; you can obtain advice from your local wildlife community group, WIRES, or the environment department of your local council.


In summary

Research shows that cats that are kept inside, with access to cat-proof yards or cat enclosures and runs, live longer, and are healthier and happier than those that are allowed to roam. In addition to being exposed to many dangers, roaming cats pose a real threat to our birds, reptiles and small mammals. Even cats that have been outside all their lives can learn to enjoy the comfort and security of home life, particularly if they continue to have safe and secure access to the outdoors.

Enriching your cat’s environment is the key to keeping your cat happy at home. Creating a safe space outdoors, or bringing the outdoors inside, can do wonders. Whether custom designed and installed, off-the shelf or DIY, there are many options (and budgets) to choose from, ranging from pop-up tunnels to multi-level cat complexes.

Outdoor enclosures may require a financial (and possibly time) investment, but once installed they will greatly reduce the risks associated with your cat being outdoors. Whatever option you choose, it is very important to supervise your cats initially to make sure they are happy in their new enclosure and to make sure that they are unable to escape. Some cats will find ingenious ways to thwart the enclosure that didn’t occur to you or the designer!
