I’ve owned pets all my life, and it would be weird for me to live in a house without some form of pet present. Currently, as a dog owner, I share my home, my bed, and my food (not by choice) with my two dogs, and I couldn’t imagine life any other way.
Pets are an important part of households worldwide, and whether you prefer to keep cats and dogs or hamsters and tarantulas, introducing a pet into your life can change the game. Who wouldn’t want a loyal best friend by their side?

Most Popular Pets: Most Common Pets
There are some pets that just stand out above the rest. For centuries, humans have kept pets for companionship, and although nowadays it’s more common to see a dog or a cat as part of the family, there once was a time when it wouldn’t have been too out there to see lions, cheetahs, and leopards as pets. Could you imagine?
Dogs
Does it come as a surprise that dogs are one of the most popular pets across the entire globe? According to Statista, in 2018, there were roughly 471 million pet dogs worldwide; in addition to what WorldAtlas says, there are 900 million dogs all over the planet.
Studies show about 60% of the world’s dogs live in human homes, while people also provide food and support for many homeless street dogs.
Cats
Are you a cat person or a dog person? I’ve always been and always will be a dog person. I say as I’m being death stared at by my two dogs for their daily walk.
I do, however, have a deep appreciation for cats and all their feline capabilities, especially their talents that lie within pest control. A free cockroach killer? Sign me up! Maybe owing to this reason, the number of pet cats all over the world is one billion, and they are one of the most beloved and widespread pets globally.
Statistics list America with 74.2 million domestic cats as the leader in the number of cats, followed by China with 53.1 million cats, where they are valued by Chinese culture as symbols of fortune.
Fish
In 2024, it was estimated that Canadians owned over 8.6 million fish as pets. Across the UK, the UK Pet Population claims that there are a further 7 million indoor tanks that play host to either freshwater or saltwater fish. As Bruce the shark would say, fish are friends, not food!
Reptiles
Reptiles aren’t my first choice of pet. I like looking at reptiles when they’re in their enclosures, but the thought of a snake potentially slithering its way through my home gives me the heebie-jeebies.
Of all the reptiles, the Reptiles Magazine recognizes that the bearded dragon was the most popular reptile, chosen by 40% of reptile owners in the US. And if I had to have a reptile as a pet, it would likely be a bearded dragon, so I can completely understand why they take the top spot.
Following the bearded dragon come ball pythons and leopard geckos. In Mexico, ball pythons were the most popular reptile, preferred by 51% of owners, while in Poland, leopard geckos ranked first at 42%.
A ball python would be a big fat no from me, but leopard geckos are kind of cute, so maybe they’d be a possibility.
Birds
One of my closest friends had a bird growing up. It was a small blue budgie with really sharp claws. It wasn’t my biggest fan, and the feeling was certainly mutual, but it does fascinate me that birds can mimic words and sounds. Like, seriously, how do they do that?
There are so many bird species that pet owners share their homes with. Notably, they include cockatiels, budgies (or parakeets, whatever you like to call them), and African grey parrots, according to PetMD.
Rabbits
Rabbits are among the most popular pets, and it’s easy to understand why. Long floppy ears, fluffy tails, and the most adorable hop, you’d be crazy if you didn’t think they were cute.
Animal Facts Encyclopedia estimates that around the world, 14 million pet rabbits are hopping away in hutches.
Livestock Animals
Have you ever thought about owning livestock as a pet? I doubt it, as cuddling up with a pig doesn’t seem nearly as pleasant as cuddling up with a dog, does it?
Although livestock typically live on farms, some people do keep pigs, cows, goats, sheep, and horses as pets.
Since 1960, the human population has doubled, but livestock numbers have increased even more rapidly; however, sadly, most of those animals don’t live their lives with loving pet parents and a warm, comfortable home, but it would be nice to think that they do.
Pet Poultry
The eighth most popular pet is those who fit under the poultry category, so we’re talking chickens, ducks, geese, turkeys, and guinea fowl. Poultry pet-owning households usually keep their birds for fresh eggs each morning; can you blame them?
As of 2025, about 11 million U.S. households own backyard chickens, and around 8 million households consider their chickens pets.
I guess some people were baking banana bread, and others were tending to their chickens. Each to their own!
Horses
My two best friends growing up were horse girls, and at times, I envied them. Not when they got up at 6 a.m. before school to muck out and feed their horses, of course, more so during the summer evenings.
In total, it is estimated that there are 2 million households owning pet horses, some with up to six!
Most Popular Pets in America
Understandably, dogs and cats will likely remain at the top spot for centuries, but in saying that, there are some other pets who could give them a run for their money.
Dogs
According to the 2025-2026 APPA National Pet Owners Survey, 71 million American households own at least one dog. Almost 4% even had more than one. Because there is only one thing better than one dog, and that’s two dogs!
Like people taking pet ownership of chickens, the Petfood Industry noted that 15% of Americans got a pet dog during the pandemic, ultimately increasing the number of dogs in the US.
Cats
According to the 2025-2026 APPA National Pet Owners Survey, 53 million US families own cats. Despite the favoritism toward canines, many families prefer cats, as, unlike pet dogs, they don’t need daily walks and are more than happy to entertain themselves.
One state in America takes cat-loving to a new level; any guess which?
You see, of all the states throughout America, Vermont has the highest percentage of cat owners. In fact, nearly 44.6% the households in Vermont own a pet cat. I wonder if there is any particular reason why cats are so loved in the Green Mountain State.
Hamsters
I had two pet hamsters when I was little. The first was Hammy. And I know what you’re going to say, it’s not the most creative name, but I was seven, and that was the best he was going to get. My second hamster was Story, who was grey all over, so again, his name sprang to my mind in less than one second.
According to the AVMA, there are 1.1 million homes in the US with a pet hamster. Taking care of hamsters is a fairly easy task because, let’s be honest, they sleep throughout the day. Many parents see hamsters as a step up from a goldfish, preparing their kids for more challenging pets like cats and dogs.
Guinea Pigs
In some countries, people eat guinea pigs for lunch. Ew. I can’t say I’d find a guinea pig even remotely appetizing, would you? And for the most part, many Americans agree because over 1.5 million have opened their home to the furry little creatures, making them the second most popular small pets in America with 23%.
Fish
The APPA states that 10 million homes in America today have freshwater fish and another 2 million have low-maintenance saltwater fish. When you think about it, you don’t normally just get one fish; you get at least a couple, as they don’t take up a lot of space. So, the amount of fish in total must be staggering!
Birds
Are you a fan of a four-legged friend or a two-legged companion? No matter which one you pick, over 6 million households in the US share their home with a bird.
It surprises me that so many people would want to keep birds as pets because, although they’re beautiful to look at, they really are kind of pointless.
Mice
I will admit that I have a fear of mice, which has likely come from the fear my mother has. Jeez, thanks, Mom!
Regardless of my views on mice, many people in America see these tiny rodents as cute, fuzzy pets, with the APPA factoring them into the 5 million small animals living their best lives in family homes.
Ferrets
Some states, like California, ban residents from keeping ferrets as pets, but that hasn’t stopped the little guys from winning over the hearts of those living in other states. Go, Ferrets!
The DFG concludes that around 6-8 million ferrets live as pets despite many states not even recognizing them as domestic animals.
Iguanas
As far as pets go, iguanas are a pretty cool choice. And what I mean by that is that although they’re a popular pet in America, I’ve never known anyone in my home country of the UK to own a pet iguana.
From the Los Angeles Times in 1995, Iguanas were seen as the most trendy Christmas pet. But remember, pets are for life, not just for Christmas.
Snakes
I live in a tropical country, and I see snakes fairly regularly in my yard. But in saying that, however, it doesn’t mean I’d want one as a pet. To me, it’s absolutely mind-blowing that in America, you can keep exotic snakes as big as boa constrictors in your home. Imagine it escaping in the middle of the night; yikes!
Pet superstores are still the top source for buying reptiles at 18%, but their share has dropped by 14% since 2023. At the same time, local specialty stores have grown to 15%, increasing by 15% in just one year.
Approximately 6 million households in the United States have at least one pet reptile. And although quite a lot of Americans are brave enough to own a snake, I know for sure that I certainly wouldn’t be.
Types of Pets
What pet is at the top of your list? The animals you can keep as pets really do vary from country to country, but there are reasons why certain pets are far more common.
Fish
Easy to look after, nice to look at, and on the lower end of the pet cost scale, what’s not to love about fish? Okay, granted, they may not be the most interactive pets of all time. But you can’t deny that they aren’t mesmerizing in their own way!
Homes all over the world have either an aquarium or ponds full of fish. My partner, for example, has a huge obsession with koi fish and has a pond dedicated to them in his family home. As a matter of fact, I already know that when we move into our future house, the koi will follow us there.
Birds
Pet owners in the UK look after 1.4 million birds, which is even more staggering in countries like America.
Birds are popular pets for a number of reasons. First, they’re fun to talk to. Second, they come in beautiful colorings and markings. And third, most species don’t require much attention. Simple enough, right?
Reptiles
If you want a low-maintenance pet that isn’t a fish or a hamster, reptiles are an ideal option.
In addition to not having to take them for a walk, many reptiles, once they reach adulthood, only need to eat once every two to three days. So, even if you don’t have the best memory, your pet isn’t going to starve to death. Unless you really forget about it, that is.
Amphibians
One pet that I could just never get on board with is an amphibian. I wouldn’t say I like frogs, especially, but salamanders and newts don’t appeal to me, either.
Just because I have a phobia (again, passed down from my mom), it doesn’t mean that amphibians make bad pets because, like reptiles, they’re incredibly low maintenance. I guess they do have their perks!
Mammals
It goes without saying that mammals are a common type of pet, more so cats and dogs as opposed to hyenas and cougars, but shockingly enough, some countries and states do allow those, too.
Common Household Pets
You may know someone with a weird, entirely out-there pet. I’m sure there is someone who springs to mind. But for the most part, year after year, there are the same front-runners for the most common household pets.
Mammals
Mammals will always remain at the top spot. They just can’t be beaten! Here are six popular pet mammal choices.
Cats
An interesting fact about cats is that, for the past 100 years or so, they have been living indoors in the US. While you may enjoy having your feline friend living indoors with you, cats are naturally and instinctively suited to the outdoors, which is why they may go wandering for an hour or two.
Dogs
Although dogs are one of the more expensive pets (if your dog has been to the vet, then you’ll know exactly what I’m talking about), the price of dog food, toys, and grooming hasn’t put many people off, as Fido has remained at the top spot for the most common pets for decades.
Gerbils
If you thought hamsters were cute, just wait until you see a gerbil. In all fairness, gerbils do look fairly similar to mice, but their big back feet and innocent little faces make them some of the cutest pets out there.
White Mice
When you walk into a pet store looking for a mouse, you’ll most likely come across a white mouse with piercing red eyes. Their eyes, at first, can seem somewhat scary, but once you get used to them and hear their little squeaks, white mice may just become one of your favorite pets.
Rabbits
Who needs a lawn mower when you’ve got a rabbit? A pet rabbit will happily munch its way across your yard, gobbling up those pesky weeds that you’re too busy to take care of, so it really is a win-win for both parties. You get a free landscaper, and your rabbit gets a loving home!
Guinea Pigs
Guinea pigs are like the next step up from hamsters. A little bit more responsibility, but nowhere near the amount of a dog. After all, they do just look like enlarged versions of a hamster.
Birds
In addition to mammals, birds are popular household pets, with four species standing out above the rest.
Parrots
How cool would it be to have a parrot? Yes, parrots are a lot more work than a guinea pig or a hamster, but the fact that they can talk to you and act affectionately is pretty awesome to me! Beautiful entertainment to keep you occupied!
Finches
Not ready to take on the high demands of a parrot? I don’t blame you, but don’t worry; you have options! Finches are a popular type of pet bird as their need for attention is minimal, and they don’t require much maintenance.
Canaries
When I think of canaries, my mind just instantly brings up a beautiful shade of yellow. Fairly solitary birds, canaries love nothing more than living out their lives alone.
Parakeets
Parakeets are dazzling, low-maintenance birds with the ability to mimic human sounds. Their intelligent little minds are partly the reason why so many people from all communities love them.
