A Rant on Outdoor Cats

Here is my controversial take: if it is true that a cat needs to be let outdoors unsupervised in order to live a happy life full of enrichment, then we should not have pet cats at all.

TW: Discussions of animal death.

Letting a cat wander outside unsupervised is cruel both to local wildlife, but also cruel to the cat.

Letting cats outside is often introducing a non-native species to an ecosystem which has not evolved to deal with cats. How is it any different to us accidentally introducing invasive rats, weasels, and other small predatory mammals into ecosystems? We invest a lot of money into ridding sensitive ecosystems of these invasive species but we turn a blind eye to cats because we selfishly benefit from them being around us, whether it's because we find them cute or because they provide a practical use for us as mousers.

I'm fed up of my neighbours cats who visit my garden. They poop in my planters where I grow vegetables that I eat, which presents a serious health risk to me. The cats predate the birds who visit my garden, which has exclusively been successful on fledglings and other young birds. So far, it has not been a species that is vulnerable and it's only common garden birds, but cats will kill indiscriminately and I have heard many horror stories of endangered birds being predated by cats owned by friends-of-friends.

A pigeon couple has been building a nest in a tree in my garden, but this morning I saw it was predated. I found a chewed open egg, and when showing a photo to my ornithologist friend she theorizes it was most likely a cat as the puncture into the egg shell will have been cleaner if it had been a predatory bird. Predation is a natural part of life, but this predation was not by a natural predator which is part of our local ecosystem and thus I am very upset...

But not only that, I believe letting a cat go outdoors unsupervised is cruel to the cat. Cats so often go missing, more often than not killed by cars. In other countries there are dangerous animals who can kill cats. This is not an issue here but I have personally had to dispose of dead cats who turn up in my garden after being run over on the road in front of my house. I don't think there is any other common pet animal where we so easily expose them to dangers we cannot protect them from.

Just to say, I do not hate cats. I do not blame the cats for pooping in my vegetable beds, or hunting on my property. They are animals only doing what their instincts dictate, and often are doing what we ourselves have taught them when we first domesticated them. Equally, to a degree I struggle to blame some cat owners as people will often argue that keeping a cat inside is cruel, and they do not desire to be cruel to their cats. The intentions are good, and education on this matter is poor.

There is an issue here which needs to be discussed, and the hypocracies we have normalized need to be challenged. For me, I feel that cats either need to be kept indoors if we can verify that this is not cruel to the cat, or we should be required to supervise our cats outdoors like we are supposed to do with dogs, or we should stop having pet cats. Having unsupervised outdoor cats is unacceptable.

Edit: Grammar and adding a TW just to be safe!

  • Looking at the comments I'm so happy Beehaw has an overall good take on this subject. With progressive mindsets it seems 50/50 whether they agree with protecting cats and the environment. There is so much science that shows having cats be outdoors not only decimates local fauna but also increases mortality of the cat up to ~80% (over the years I've seen studies on that subject ranging from 67% to 85%). Keep your cat inside if you care about it, if it's bored you're not playing with it enough or don't have a good environment for it to explore and keep entertained. Pay attention to your cats.

  • It's a rant, I'll add on with one of my own.

    I absolutely, really, hate that this gets spun around as "keeping a cat inside is cruel" or "my kitty is innocent" or whatever.

    "Don't let your cats outside because it's dangerous for them!!". No, it's really not. The cat IS the danger. The hedgehogs, the birds, the polecats, all other small to medium mammals are terrorized by your cat. The actual medium sized predators are forced out of their territories, because they actually have to live on the food they catch, and don't just hunt for fun.

    I really don't care if it's cruel to the cat if it's kept from killing hundreds of animals over the course of its life. But it's always about the "cute little uwu kitties".

    And the idea of a neighborhood cat is somehow normalized. It's normal to see a cat on the street for some reason. They're "cute", and every neighborhood has at least one. Awesome.

    You might think I'm irrationally angry about this. But the fact is, that cats kill billions of birds [1] in the U.S yearly. Do you know how much a billion is? It's almost unimaginable.

    But it's somehow normal. And I come across as a cat hater when I mention this to people who let their cats outside.

    I wish I could like cats, and I did use to. But now, they're just a symbol of death for me.

    [1] https://www.nature.com/articles/ncomms2380 (I'm aware that ~70% are caused by un-owned cats, but how many cat ladies supporting them are in your neighborhood?)

  • As a dog person, I haven't enough personal experience to know if keeping cats indoors is actually as bad for them as people might think, but I can share that a best friend of mine who has a now 10 yr old cat named Buddy has kept him in their house since he was a tiny kitten. You can put Buddy on the deck outside their kitchen, the patio in their yard, or just in front of an open window and he appears to literally care less about even thinking of leaving the spot. He is a skinny cat but pretty strong for his age, playful, seems very affectionate, and totally disinterested in being anywhere my friend and his family isn't. Maybe it's a question of socialization for the cats?

  • I agree. I live in a rural area in a country where cats were seen as farm tools rather than living beings and pets until very recently, and keeping a cat indoors is believed to be “cruel” by most, but I see cats killed by cars incredibly frequently.

    Also, I have two highly prey-driven dogs who are always controlled except when they’re in my walled back garden. The neighbour’s outdoor cat wandered into my garden, and it ended in a tragedy that left both me and the neighbour traumatised. The cat didn’t survive. It was in no way my fault, or even really the dogs' fault- the cat should never have been allowed to wander into the dogs' space on my property.

    Then the neighbour tried to have our dogs put down, claiming that the dogs had come into her garden, killed the cat, and returned to our garden. Thankfully the dog warden who came to investigate saw that this was patent nonsense- we have a double-gated 3-metre wall with wire across the top on the neighbour’s side, it’s not possible for the dogs to escape into the next garden and quickly return.

    So the neighbour built a catio for her new cat and does not let it wander. I am deeply sorry that a cat died before she came to that conclusion, but she should have controlled her animal just as I control mine.

  • I love birds. I have a couple myself but I also put considerable time and effort into making my garden a place for them to visit. I'm sure you know where this is going.

    I hate that there's nothing I can do to keep cats out of the yard. I hate that people are too lazy to provide enrichment for their pet indoors and feel entitled to inflict it upon the neighborhood instead. I have had to clean up dead kittens who got hit and crawled under my car to die. I have had to clean up full dead families of birds I rarely get to see anymore who I somehow lucked into enticing them to nest nearby. I have found full nests of dead newborn rabbits with my lawn mower because they had been left scattered dead in tall grass and already teeming with maggots in the summer sun.

    I don't understand why all of this has to be my problem. There is quite simply nothing good about letting cats outdoors. If they're not fixed, they create kittens who end up dead. If someone tries to control their hunting with a bell on the collar, they just adapt and go on killing. They shit and fight and die miserable deaths, and for what? Why are people so stubborn and just straight up mean when it comes to keeping your pet indoors? You can show someone the statistics and point them to resources for indoor enrichment and they get mad about it. I don't get it.

  • I've heard that putting a bell and a bright, reflective collar on a cat can prevent them from hunting wildlife.
    Does anyone know how true this is, or if doing so would negate some of the risks of having an outdoor cat?

    • There's also this: https://www.pets4homes.co.uk/pet-advice/does-putting-a-bell-on-your-cats-collar-stop-them-from-hunting.html

      Will a collar bell warn prey in time for them to get away? ... When it comes to birds, cats are usually far less successful at catching them than they are with rodents. Exceptions to this are baby birds and fledglings that are unable to get away, for which a bell wouldn’t help.

      This reminded me of an experience I had personally. TW: Animal Death

      I had a very young Starling, it had only fledged the nest within the last day or two, soaking in a bird bath I had in my garden. A cat pounced out from behind one of my bushes and frightened it into taking flight. But it's feathers were too heavy with water and it did not have the strength to surmount the fence of my garden and crashed into it. The cat promptly pounced on it. A bell or a reflective collar would certainly not have helped in this situation.

      It also would not have helped with the anecdote from my original post regarding the pigeon eggs which were eaten by a cat this morning in my garden...

    • I've done a bit of reading on this and here's some reading I've found:

      From: https://kb.rspca.org.au/knowledge-base/how-can-i-reduce-or-prevent-my-cat-from-hunting-prey/

      The only effective way to completely prevent your cat from hunting prey is to keep them safely contained at home.

      Research has found that bells on collars are relatively ineffective [2] but other research has shown that some specially designed cat predation devices may reduce predation [3, 4].

      From: https://www.mcgill.ca/oss/article/general-science/should-i-attach-bell-my-cats-collar

      A number of studies have looked at whether or not bells help prey escape from cats [1] [2], and the general consensus is yes! Bells on collars seem to reduce the amount of prey caught by about half, which could be enough to no longer pose a threat to ecosystems.

      Some owners worry that as well as alerting prey, a bell would also alert large predators to a cat’s presence. While this is possible, given most predator's acute hearing, it’s unlikely that the relatively quiet noise of a bell would make the difference between your cat getting detected or not. If you live in an area where your cat is at risk of being attacked by large animals you should probably be keeping your cat indoors anyway, or at least supervise their outdoor activities.

      TL;DR Bells and bright reflective collars at best reduce the success of cats when hunting but it certainly does not completely prevent them from being successful when hunting. However it may put them at greater risk of danger from large predators and if your cat is at risk of being attacked by large animals then it should be kept indoors or supervised.

    • Thought on it is split. This article has some decent citations on for and against as well as ways to keep an indoor cat more than happy:

      https://www.toe-beans.com/blogs/pet-blog/case-for-against-bells

      My personal experience with years of pet sitting and just being familiar with many different cat personalities is that it can help, but it can also be adapted around and does nothing for the other major risks of being outdoors. They will still try to hunt wildlife. A baby bird, for example, probably won't get to observe the significance of a cat bell before meeting one in a close encounter.

  • The problem from my point of view is people not spaying/neutering cats, and then inevitably a feral population will show up. Many cats can have a litter at 6 months old. I've personally watched generations of cats grow outside my workplace.

    It's a huge problem. All the local shelters are beyond max capacity JUST FROM CATS. Feral cats explode in population, and the only real way to get populations under control is more Trap-Neuter-Return programs along with educating cat owners on why they absolutely must spay/neuter. There is no excuse not to.

    https://www.alleycat.org/our-work/trap-neuter-return/

  • I always see folks say that cats being outside is bad, that they’re a non-native invasive species.

    So, I got to wondering….exactly where are cats native and non-invasive, but aren’t inside a house?” houses and dwellings for cats didn’t always exist. I don’t need to be explained to as to why cats should be inside, what I don’t understand is the missing logic about them not being outside.

    • Cats might not look like much, but they are some of the most successful and prolific hunters on planet earth. And they also kill entirely to keep their skills sharp.

      So as you can imagine, combine an instinctual need to kill for sport with an insatiable desire to explore, you've got extremely efficient bird death machines that operate in mile-wide radiuses.

      Keeping cats from going outdoors just helps to limit needless disruption to a clade of animals that is already extremely sensitive to deforestation and other external factors.

      • Put a bell on your cats, and the core of the argument kind of vanishes!

        A little bit of owner diligence sorts that problem out. Do people always do this? No. But if the argument is "Outdoor cats are bad because they hunt indiscriminately" than that argument is no longer valid and is instead "Cats that don't have bells are a danger to their environment" no?

        Edit: Bells are not a 100% effective solution as pointed out by @Jho@beehaw.org, they reduce cats hunting effectiveness in ~1/2. I was being too sassy, and got carried away.

    • In the end, it's a numbers game. Wild populations of cats around the world don't hold a candle to the amount of domestic cats. That's what ends up making it so damaging to wildlife. There's no shortage of people enabling cat populations either. It's inevitable when the animals in question are so cherished by humanity. Feral pigs would be another case of domesticated animals ruining habitats and killing wildlife. They are routinely destroyed, and for good reason. With cats, you're far more likely to see someone feeding a feral population than gunning them down the way hogs are. It's just the reality of our attachment.

      • You can't get rid of cat populations by killing or relocating them anyways...

        They will move back in from neighboring areas.

        You do catch, spay, neuter and release. This is a fundamental tactic to controlling feral cat populations.

  • .... Put a bell on your cat. Problem solved.

    We have 1 indoor/outdoor cat. She LOVES to go outside, if she's stuck inside she gets matted fur, gains weight, and is generally angry/sassy. If she gets to go out, she's a happy kitty. And she can't hunt outside animals because of her bell.

    This post appears to be based on a general lack of knowledge or understand of feline behavior and needs. You appear to be thinking cats are dogs, which they are not...

    "It's cruel to the cats". No, no isn't, you're projecting onto cats. Sure, some people leave their cats out to starve and fend for themselves in an urban environment, that can be cruel. But a cat being outside is not cruel, and it's rather asinine to say so.

    • It's pretty cruel to put your cat in a prime position to get hit by a car though

      • Or to come into contact with coyotes and raccoons.

        It's also just ultimately selfish to not put the work in to provide indoor enrichment. Of course it's not an easy adjustment when the cat is used to being outdoors, but it's doable. Just requires some effort on the part of the owner.

      • By the same note, it's cruel to let your kid play outside for the same logic no? Or for you to let your spouse drive anywhere? How could you let them use the sidewalk when you know there is a chance they could be hit by a car? You are putting them at risk, shame on you for being a bad parent, and a bad spouse to put them at risk. (See how circular that logic is now? It can be applied to everyone and everything)

        Quality of life depends on a certain level of risk in every case.

        I don't want my cat ran over, that's why the other 5 are indoor only. The 6th is indoor/outdoor because she is happier that way, and was a rescue who would otherwise be dead.

        I put value in my animals quality of life, and I'm not so selfish as to detract from it because I'm scared for them. If that quality of life depends on them wandering about the back yard, then I do what I can to facilitate it so they are happy.

        She has a bell breakaway collar so she can't hunt, she has a chip so she can be identified, water and food is put out and removed daily, a stand is out on our porch so she hangs out there....etc implying that cat owners are negligent just because they don't meet your one specific criteria is almost toxic.


        The armchair argument you are presenting is black and white, AND circular, which means it's ignoring the nuances and is peeping in through a slit just big enough to be critical of others but not big enough for there to be actual understanding. Almost a fallacy really 🤔


        Edit: Maybe I should leave this thread. After I got my first cat I was fascinated by their behavior, and started learning about their characteristics and the science behind them, and eventually started rescuing cats (Which is how I ended up with 6...).

        So I'm emotionally attached to the topic, and find the quality of the stances in this thread to be both dissipointing and frustrating. Especially when those stances are both cherry-picked and accusatory, and expect the cat owners to defend themselves instead of discussing the nuanced topic. And when replies only pick one small piece to argue against, instead of the topic as a whole.

  • Does your opinion change regarding outdoor cats in a rural situation, like a farm?

    • Yes, I think so. But I'm not entirely sure of my opinion on this.

      I'm sure there are many people out there who rely on their outdoor cats for survival to prevent their food harvests from being plundered by rodents, either because it's their entire income or because it's food they consume themselves.

      I am in a position of privilege and do not have to worry about procuring food and my income which I use to survive is not affected by such issues. It certainly feels wrong for me to say that in these situations people should not have outdoor cats when it is not an area I understand very well nor are these problems I face myself.

      But of course, cats kill indiscriminately and will not be able to distinguish between a common rodent and an endangered bird. My hope is that there could be an alternative solution which is less destructive to local ecosystems which anyone regardless of wealth could deploy. But I certainly don't know of such a solution.

      • As a person who lives in a farming area- the farmers keep cats, but they are not pets- they're generally almost completely feral, allowed to breed uncontrolled, sometimes are not fed by humans, and when they inevitably wander into the road and are killed by cars, they are thought of as expendable- there are always more to replace them. I agree that there is probably no better rodent control, and rodent control is very necessary, but there has to be a better way to do it than using free-roaming feral farm cats.
