Today we broach one of the great cat debates. Cat people are usually united by their love of felines, but there are a few topics that can tear us apart. This is one of them. Perhaps this is due to the changing relationship between humans and cats, something that has continued to evolve ever since cats domesticated themselves. It used to be the case that almost no one had indoor-only cats. However, as humans became more urban and cats came to be seen more as companions, more people have chosen to bring cats inside with them. Some, however, still think cats belong entirely or partly outdoors. We all want to think that we are doing the best thing for our pets, but is there a right and wrong answer here?

Veterinarians and animal welfare agencies, without exception as far as I can tell, recommend keeping cats indoors. Before anyone starts to leave an angry comment, this is not to say that there’s no benefit to cats being outdoors. In fact, those who say that cats belong in nature are correct, cats evolved to live outside. Of course, so did humans, but that is beside the point. Being outside is good for cats’ mental health because it provides them with a wealth of stimulation. They are able to exercise, hunt, socialize with other cats, solve problems, and generally be a cat the way they were meant to be. So, yes, cats do enjoy being outside, and in some ways it is good for them. But it is not without reason that experts recommend making our feline companions indoor-only.

The average lifespan of an indoor cat is about fifteen years, but for outdoor cats it’s only two to five years. There are a lot of dangers that cats face in the big, mean world, regardless of the setting. Cars are a major killer of cats. Cats may learn over time to avoid cars, if they are lucky enough, but they do not instinctively know to be careful of them. Cats are even injured and killed when they crawl inside cars for shelter and don’t have time to escape when the car turns on.

They also in danger from a number of predatory animals including hawks, foxes, coyotes, bears, alligators, and many others, depending upon the environment. Dogs, whether pets or strays, kill cats, and cats get into dangerous fights with each other. Certainly, cats have some natural defenses against predators and other cats, but they can’t always emerge victorious. What chance has a cat against an alligator? And even if the cat is able to fight off the predator or aggressor, it may still be seriously injured.

Cats also face the threat of disease outside. They may pick up infectious diseases from contact with other cats, such as Feline Immunodificiency Virus (FIV, the cat equivalent of HIV), Feline Leukemia Virus (FeLV), panleukopenia, and upper respiratory pathogens. FIV can be fatal, and there is no vaccination or cure. The only way to prevent it is to prevent infection by preventing contact with infected cats. There are lots of parasites out there, too, some of which can be passed to humans and carry other diseases. Cats may also come into contact with toxic plants or chemicals that could sicken or kill them if ingested. Many cats like to eat plants, and there are a whole host of toxic plants out there, especially in gardens. Antifreeze apparently has a pleasant taste, and cats have been known to eat it if they find it lying around.

Then, of course, there are the human dangers. There’s no telling what someone might do to your cat if you aren’t there. On the benign side of things, cats might be mistaken for strays and taken in to an animal shelter. Then there are those whose intentions are not to be admired. Animal cruelty is real and it happens. Friendly, free-roaming animals are easy targets. I won’t go into the grisly details of the horrible things people have been known to do to cats. Suffice it to say that two of the more common include shooting them with arrows and bb guns. Cats are also used as bait animals in dog-fighting, although it’s hard to say how often free-roaming pets are stolen for this purpose because there is simply so little data.

With all that being said, there are some disadvantages to keeping cats strictly indoors. Without the stimulation of being outside, they may become bored or even anxious or depressed. They can start to be very dependent on their human, or they might develop behavioral problems such as destructive tendencies (scratching, chewing, etc.), eliminating outside the litter box, or aggression. Individual cats can exhibit any number of signs of stress as a result of not being to act out all their natural behaviors. So, what can we do? It’s too dangerous outside and too boring and confining inside. There are a few ways to compromise.

First, the indoors doesn’t have to be so boring. Cats need lots of places to climb and hide, and lots of surfaces to scratch. Every cat has their own preferences in all of these regards, so you may have to do some experimenting. A good cat tree is always a place to start. Make sure the cat tree has a wide, stable base and any scratching posts are tall enough for your cat to stretch out to their full length on. Many cat trees don’t meet these requirements, thus are unlikely to see much use.

Toys are also key. Not every cat likes the same kind of toy because not every cat is the same kind of hunter. Most cats will need some toys they can play with on their own as well as interactive toys for you to play with them. Interactive toys allow you to really simulate a hunt for your cat. This especially helps them to exercise and feel like they’re out in the wild.

Another thing you can do is “cat TV.” We know that cats like to watch the great outdoors out the window. Putting a bird feeder or something similar outside the window to make the view more interesting is a good idea. It also helps to make sure that your cat has a good perch by the window(s) so they can watch in comfort. You wouldn’t want to watch TV sitting on a narrow windowsill, would you? If you don’t have windows, don’t have much of a cat-friendly view, or just want to try other options, there are videos of literal TV for cats that you can put on. Or you can try making a terrarium, aquarium, or paludarium (that’s a combination of both) with some small animals that they would like to watch. Just be careful that they can’t knock it over!

If you would like to let your cat really experience the outdoors, well, outdoors, you still can. There are a few options that allow you to keep your cat safe while also letting them enjoy the nature. One is to harness train your cat so you can take them on walks. That may sound like asking for a clawing, but it doesn’t have to be. See my previous article for a how-to on walking your cat.

If you or your cat don’t care for that idea, however, don’t fret. If you have a suitable yard, there are cat-proof fences designed to keep your cat from jumping out. Cats will not jump if the fence has a top that is angled above their heads sharply enough. They know better than to bump their heads! There are products that can be attached to an existing fence as well as entire fencing panels built this way. Or you can do it yourself, if you’re handy. Just make sure to supervise your cat while they’re out in your yard in case something else gets in.

Perhaps the most flexible option is a catio (cat patio). These are a wide variety of cat enclosures that allow cats to be outside while still being enclosed. If you already have a screened-in porch, that qualifies. For everyone else, there are ready-made catios that you can buy which accommodate a variety of homes. Some are meant to attach to apartment windows or to sit on balconies or porches. Others are meant to sit in yards or attach to houses via a cat door.

There is also the option to build one yourself or have one built for you. The catio concept is very customizable to the needs of you and your cat. Just make sure that it is sturdy enough to withstand your cat from the inside, especially if they are an escape artist or a screen climber, and any predators or other cats from the outside. If you want to put plants in your catio, make sure they are safe for cats.

If you still choose to keep your cat outdoors, please do so responsibly. Bring your cat inside or at least into some sort of structure at night and during extreme weather. Feeding your cat when you want it to come in will make sure it does so. Take your cat to the vet regularly and keep it up to date on its vaccinations. Maintain flea, tick, and heartworm medication, and have your cat de-wormed regularly. Make sure your cat wears a collar with rabies tags and an ID tag with your contact information. However, the collar needs to be a breakaway collar. Cats are prone to getting their collars caught on things, and other collars can cause them to get trapped or suffocate. Given that the collar may come off, it is important to also have your cat microchipped.

It should go without saying, but you absolutely need to have your cat spayed or neutered if they are going to be an outdoor cat. Not only will this prevent overpopulation, but if you have a she-cat this will save you from unwanted kittens and pregnancy-associated health problems. Furthermore, intact cats of either sex wander farther and get into more fights, especially toms.

An important note: if your cat is declawed, they cannot be an outdoor cat. They can still have supervised outdoor time, but they cannot be allowed to free-roam. Declawed cats can’t defend themselves well at all and are in much greater danger than cats with all their defenses in place.

So, do cats belong outside? Well, yes, they do, a biopsychological sense. But as pet parents we have committed to taking the best care of our cats we can. So we need to keep them safe, in our homes. But that doesn’t mean cats should be bored, or even that they can never be outside. We probably should take them outside, but as their guardians it is our responsibility to go outside with them and make sure no danger befalls them. That is the distinction between an outdoor cat and an indoor cat that is momentarily outdoors. Our furry friends deserve the best lives we can give them, both long and happy. A rewarding indoor life with supervised outdoor time is the way to give them the best of both worlds.
