Should we keep cats indoors?

In recent years, there has been a noticeable shift in society's attitudes towards cats, particularly concerning their safety and environmental impact when allowed to roam outdoors. But can we realistically give them a Good Life indoors – and if so, how? 

The way we live is changing, and that has implications for both us and the cats with which we share our lives. Increased urbanisation means more of us are living in apartments with limited outdoor access. With growing awareness of the dangers posed by predators, traffic, and disease, coupled with the detrimental effects of outdoor cats on native wildlife populations, conversations surrounding the importance of keeping cats indoors have gained traction.  

The New Zealand cat conversation 

Some animal welfare organisations and pet owners are increasingly advocating for indoor lifestyles for cats, emphasising the provision of enriching environments and stimulating activities to ensure their needs are being met.  

In New Zealand, the National Cat Management Strategy Group (NCMSG) has extensively reviewed cat issues in New Zealand and recommend comprehensive cat management, including requirements that companion cats be desexed and microchipped (with microchip details registered) and kept on the owner’s property. This, combined with a review of the Predator Free 2050 strategy this year set to discuss inclusion of feral cats, will mean the “cat conversation” is only going to become more prominent.  

It’s important here to distinguish between the three categories of cats – companion, stray and feral. While we are addressing only companion cats here, the conversations about all cat categories inevitably impact opinions on each. 

What’s fueling the indoor trend for pet owners? 

Some people are making the decision to keep their cats indoors some or all of the time, usually overnight, particularly as urban environments become busier and traffic increases. In fact, research suggests that internationally, the major concern for most cat guardians is the risk posed by busy roads. 

Cats are also more likely to be kept indoors if they are pedigree, getting older or their carer is worried they may get lost (which is why microchipping your cat is essential and, if possible, using visible identification too). 

For some, the shift to keep cats indoors signals a desire to mitigate the negative ecological consequences associated with free-roaming felines.  

Can an inside-only feline live a Good Life? 

Interestingly, there is still a lot we don’t know about how people seek to provide positive environments for cats in our homes. This means there is more to learn about how being indoors affects cats both behaviourally and psychologically.  

However, there are a number of ways that we can improve the wellbeing of our companions if they’re indoors. There are also signs to look out for that may tell us whether our cats are enjoying their inside time or if we need to make some changes to their environment to maximise positive experiences.  

If you’re considering an indoor lifestyle for your cat, it's important to remember that all cats are individuals. Some will happily live indoors, or even choose to remain inside when access to the outdoors is available.  Others may be less adaptable - there is no one-size-fits-all approach. 

Baby steps... 

If your cat is already living with access to the outdoors but you want limit that for some, or part of the day, it’s important you don’t take an “all or nothing” approach. Much like people, cats will prefer to take a gradual approach to major lifestyle changes. Try bringing them in for short periods, gradually increasing duration over time.  

Make sure that time indoors is linked to positive experiences like play, cuddles, favourite treats or even just some quiet time. What they think is positive is dependent on your cat's individual preferences and personality. At first your companion may hang out by the door or increase how much they meow, so try distracting them with something fun and engaging. But, if this doesn’t settle down after a few weeks, “strictly indoors”, may not be the best option for your cat. In these instances, some people may choose to keep any future companion cats inside (exclusively or for the most part) from a young age instead so there is little adapting required for that animal.

Watch their waistlines 

As for many of society’s companion animals, obesity is rising as access to treats and good nutrition increases. This can be made worse by an indoor lifestyle which tends to be more sedentary. There are a few things that we can do to minimise this risk, although it can be hard to resist feeding our pets when they enjoy it so much.  

• Make sure that you keep a record of your cat’s weight after visits to the vet and check for any consistent rises.  

• If you provide lots of treats make sure that you deduct these from your daily feeding. Like lollies, they aren’t an everyday food and can be treated as “instead of” rather than “on top of” meal portions.  

• Measure your cat’s intake and aim to feed according to their weight. All pet food packages come with recommended feeding amounts based on your cat's weight, and sometimes even their lifestyle. Some cats will graze little and often, but others will eat everything you put out in one sitting. Following the manufacturers guidance may take a little extra time, but it’s the best way to ensure there is enough, but not too much. 

• Provide an interesting environment. This will promote activity and, as we all know, good exercise helps keep everyone fit and healthy, cats included. You can think of cats as living in a three-dimensional play space. Unlike us, they can fully utilise vertical space, so make sure there are places to climb, jump and rest - complexity is key. Try introducing new toys and climbing spaces regularly or swapping them around because novelty increases time spent playing and exploring. 

Setting the right scene 

If a cat is brought indoors, remember that a lot of the things they used to do outside they now need to do indoors. This means making sure there is access to fresh water. Many of us don’t know that cats prefer to drink away from where they eat, so provide the two some distance apart rather than a combined food and water area. 

Enrichment for indoor cats should be aimed towards engaging them in activities that provide for their behavioural needs.  Elements of the normal hunting behaviour of cats for example, such as stalking and pouncing, can be satisfied through use of cat toys that may also provide stimulation for their specialised sensory capabilities such as sight and smell.  

These are highly motivated behaviours that if unable to be expressed in some form or another may lead to the animal developing problem behaviours or abnormal responses. Providing for safe and more acceptable expressions of what are normal behavioural needs for cats will go a long way towards enabling cats to live a good quality of life, even when they may not have access to the outdoors or natural outlets for their behaviours. 

Of course, you don't need to use store bought toys. Feel free to get creative - many cats happily play with house hold items, like rolled up tin foil ball or a cardboard box with holes in it that encourages exploration.

Also make sure that the litter tray is somewhere quiet and, if you have more than one cat, there needs to be more than one litter tray. Change it frequently so there are no accidents, as cats prefer their toileting areas clean. It’s important to note that, if accidents are occurring frequently, there may be other issues that require a visit to the vet. These could include kidney or bladder issues or even the onset of senility in older cats. 

Give them quiet comforts too 

Not all cats enjoy the hustle and bustle of a busy household. If you have young children or other pets and notice your cat is frequently absent, they may not always be comfortable in the main living space.  This doesn’t mean they can’t live indoors, it just means that you have to provide a quiet and private space where they can relax undisturbed.

Although it can sometimes be hard if we want to socialise with our cats, we need to respect their choice to be alone, and let them have their quiet time. However, if they are always hiding this could be a sign that things are too stressful and we may need to consider if an indoor lifestyle is the right choice for them.  

If you have more than one cat you should also monitor them. Cats are described as “semi-solitary”, so they don’t always get on with one another. Look out for signs such as being protective of food or spaces such as doorways, or even just never being in the same space at the same time. If they don’t seem to be getting along, you may need to provide additional private spaces to allow cats to navigate the house without bumping into one another too often. It’s also recommended to have one more food and water bowl than you have cats (so three bowls if you have two cats). 

The final word  

Ultimately most cats can adapt to an indoor environment if we take time to make sure the house meets all their needs. This means a Good Life is possible indoors under the right circumstances.  

With discussions around indoor cat care becoming more prevalent, it is equally important to continue raising awareness around the needs of our companions so they can live the Good Life they deserve with responsible, loving guardians.
