Hamsters vs Guinea Pigs – Take It From Someone Who Owns Both

If you’re aching for a pet but can’t decide between a guinea pig or a hamster, let me help you. I have a Syrian hammy, and 2 guinea piggies and believe me, there are some very important differences between them.

In this article we’ll look at the main differences between them, and how much they both impact your life, so you can take a very well informed decision. If you’d like to know what would happen if you were to raise a hamster with a guinea pig in the same cage, you should read this article.

Deciding between a guinea pig or a hamster

That one is completely up to you. Decide after you’ve read this entire article, and see which would be best for you.

I got a hamster at first, a Syrian male named Teddy. About a year and a half later, we got two piggies from a friend who did not have the time to look after them anymore. We’ve named them Jessi and Ka, because my piggies when I was young were named Jessica (both of them).

So I’ve come to know some clear differences between hamsters and guinea pigs, and some common grounds as well. But let’s start with the basics.

A quick rundown on hamsters

Hamsters are nocturnal/crepuscular animals, and will sleep most of the day away. Their diet is made of mostly grains, with some fruits, veggies, meat, and nuts added to the equation.

They need fairly large cages ( a minimum of 24 x 12 inches, and about 12 inches tall. That’s 61 x 30.5 cm, and about 30.5 cm tall.) and certain conditions to live in. Hamsters are solitary animals, even if you’ve seen some people keep pair of hamsters in the same cage.

There are 5 types of hamsters:

  • The Syrian hamster, the largest one and with the most coat color variations
  • The Roborovski Dwarf, the tiniest of the Dwarf types – only 2 inches/5 cm
  • The Campbell Dwarf
  • The Djungarian/Winter white Dwarf
  • The Chinese Dwarf

You’ll rarely find all 5 types of hamsters in a pet shop, but you might find 2-3 types at a time. Syrians are the most common hamster you can get as a pet.

The average hamster’s lifespan is  2-3 years. The Chinese Dwarf has the shortest lifespan, around 1.5-2 years, while the Robo Dwarf can live up to 4 years.

A quick overview of guinea pigs

Guinea pigs are larger than hamsters, about 20-25 cm/8-10 inches long and with a very wide array of colors. Some are shorthaired, some have long hair, some have swirls in their fur as a pattern, but their personalities do not vary from one fur type to another

Guinea pigs live in herds, one male leading a groups of females. With pet piggies this is not wise, unless you’re looking to breed them.  Pet piggies are usually kept in all male or all female herds, and if males are ever kept with females the male is spayed.

Their usual diet is made of timothy hay, along with leafy greens, some root-type veggies, and the occasional fruit.

Guinea pigs have an  average lifespan of 6-8 years, though there have been piggies that lived over 10 years, so getting a piggie is a commitment.

For the most part guinea pigs are neither nocturnal nor diurnal. Instead, they sleep in patches throughout the day, and have a certain sleep schedule you’ll be able to observe after a few weeks.

Different temperaments between the two pets

Both the hamster and the guinea pig are prey animals. They’re both skittish and both need some time before they’re comfy with you picking them up. Sometimes they’re never okay with that.

But the common grounds stop there. There are many differences between hamsters and guinea pigs. When it comes to which would make the best pet for you, you need to take those into account.

About the guinea pig’s personality

Guinea pigs are herd animals. As such, they’re much more social and laid back than a hamster, who is a solitary animal. In fact, keeping a guinea pig alone is  a terrible idea, even if you’re always there to play with her.

The company of another piggie can’t be replaced with human interaction, simply because we don’t understand piggies as well as another piggy. So, guinea pigs do well in groups or at least pairs.

They can have varying personalities, the piggies themselves. Some are more outgoing, curious, and might come to check you out. others will shy away and rarely leave their huts if they know you’re there, even after taming them.

Some will be relaxed and won’t protest when you pick them up, some will try their hardest to get out of your hands.

Piggies rarely ever bite, even when they’re stressed. They can bite, yes, but they’re very docile and will avoid doing this most of the time.

It varies from piggy to piggy. The one we have, Ka is a bit more outgoing, and is okay with being held, while Jessi hides most of the time. They don’t really get along and need 2 separate cages, but they talk to each other a lot.

Another thing about a piggy’s personality and temperament, they are easier to bond with a young piggy. So if you’ve got an adult piggy, and bring in a young one, the young one will learn from the old one and become submissive.

To even things out, it’s best to always get both or all the piggies young, and introduce them as youngsters so they can grow together and form their own relationship.

Guinea pigs actually become depressed if they’ve got no friends, even if they do have human company. This is another reason to never keep a lone piggy.

About the hamster’s personality

A hamster, on the other hand, is very territorial. He has his own things, and will not share them with anyone. Putting two hamsters together is generally a bad idea, even the Dwarf types. While they may tolerate each other, they usually end up fighting and need to be separated.

Hamsters are also skittish and will try to run away or hide when you try to interact with them. But they can be tamed, at least a bit, to know that you’re no danger to them.

They have no problem biting you if you handle them wrong, or they feel threatened. For example my Teddy is a bit of a Rambo type, always curious, will fight anything (even a toilet paper roll) if it gets too close, and doesn’t really like to be held for more than 3 seconds.

Some hamsters are a bit more tame, for example a family friend had a hamster named Oscar. He was the tamest, most relaxed hammy, and he let anyone hold him.

The thing is hamsters are not very cuddly creatures, and won’t seek out your hugs and scratches on their own. Maybe a few select will, but as a whole this is something they learn to associate with food, and nothing more.

Kid-friendly or quiet home ?

Another important aspect, and a possible deal breaker for many people out there. If you’ve got children, or other small pets, the a hamster is the worst idea ever.

This is because hamsters are very sensitive to everything – the room temperature, the noise level, the light level, drafts, being picked up wrong, being held too long, a sick person, and so on. Guinea pigs are sensitive too, but much less than hamsters.

A hamster can get stressed very easily and develop an entire host of illnesses based on stress. A curious cat or a barking dog can be too much for the hamster, and kids continuously prodding at their cage can be very stressful.

A guinea pig on the other hand is more relaxed. They don’t like being woken up and put on display either, but they react much less negatively than a hamster, and they recover pretty quickly.

For kids I think a guinea pig is the best choice, instead of a hamster. I’d recommend a hamster only to quiet, patient, calm people who have time at night to tame and play with the hamster.

A rowdy home with many pets and young children is not recommended for piggies, nor for hamsters.

Feeding requirements for hamsters and guinea pigs

Both the guinea pig and the hamster have very specific feeds. While a hamster could steal anything the piggy would eat (except the hay), a piggy couldn’t eat much of the hamster’s food.

There is also the question of how often to feed them, and how much.

For Syrian hamsters 2 teaspoons of commercial food mix is enough, daily. The Dwarf types only need one teaspoon. Much of the food will be hoarded for later snacks.

Guinea pigs, on the other hand, need a fresh supply of timothy hay, available at all times, in endless amounts. Commercial food mix should be given 2 tablespoons per piggy, daily.

So on short, you’re going to feed the piggy more often, and in larger quantities. There always needs to be a hay bag on hand, to re-stock their hay pile. Both Jessi and Ka go through about 3-4 fistfuls of hay, each, per day.

Both guinea pigs and hamsters can be fed various treats that are already in your pantry or fridge. Fresh fruit and veg are favorites, a few examples include:

  • guinea pigs – raw bell pepper, lettuce, cucumber, carrots, small slice of apple
  • hamsters – cucumber, carrots, peanuts (unsalted, shelled), plain cooked chicken

While the hamster will pick up all the food in his food bowl and store it in his nest for later use, a guinea pig does not. Piggies pretty much mess with their food and it ends up all over the cage.

For example ours put a paw inside their bowls and tip them over to get to the feed. If we put the feed directly on their bedding, half of it ends up forgotten in the bedding.

Exercise and floor time for guinea pigs and hamsters

This is a very big difference between hamsters and guinea pigs. They both need exercise, and will run around pretty much all their waking time. But, they do it differently.

Hamster exercise and running routine

Hamsters are famous for their running wheels and exercise balls. We’ve all seen or at least heard of a hammy running as far as his little feet can take him, all night long.

Given their small size, agility, and how hard they are to catch in general (especially if lost), hamsters aren’t let outside their cage often. In fact, the only way a hamster can spend time outside his cage is inside his exercise ball. This keeps things safe for everyone involved.

Even then, they should not be kept in the ball for more than 30 minutes at a time. They will need water, a quick snack, and they will probably need their pee corner as well.

Most of the hamster’s exercise is done inside the cage. This means that whatever running wheel you end up getting your hamster, it better be sturdy. He will use it every night, for hours on end, pretty much all his life.

Hamsters can get bored very easily if they’ve got no way to expend all that energy. Many times this can lead to chewing the cage bars, or even trying to escape.

Some people decide to let their hammy roam free in a hamster-proof room. This means that the room needs to have no hidden corners, or furniture that the hamster can get under, behind, into or between (hamsters are ridiculously good at this), and have no exposed surfaces that can harm them. Or that the hamster can harm, like a power strip cable, or charger for example.

If you decide to let your hamster have floor time, have a good plan to catch him. Baiting him with food into his cage or exercise ball usually helps.

Guinea pig exercise and floor time

Guinea pigs are fairly different from hamsters in this respect. They need plenty of exercise too, but it’s a bit hard for them to get a good wheel, and an exercise ball is not a good idea.

The main reason is that both a ball and an wheel need to be very large in order for the piggy’s back to be straight. Most people don’t have room for such a large wheel in their home, let alone the piggy’s cage.

So that leaves the guinea pig owner with two choices: get a very very large cage, and/or supplement it with lots of floor time. Now, even if you do have a very large cage for the guinea pig, it’s probably not enough.

This is because they need to be able to roam as much as they like, at all times. As large as a cage can be, it just isn’t enough and becomes repetitive.

Some people dedicate an entire room to the piggies. That room is guinea-pig proofed, meaning the floor is easy to clean (piggies pee and poop incredibly often), there is no furniture the pig can chew on,  there are several huts/hideouts the pigs can use, and they are well contained.

If you’ve got the spare room for that, it would be a great treat for your piggies, giving them so much space all for themselves.

But, if you’ve only got the cage, you will need to improvise with floor time. This means that a certain patch of a room you designate will have to be guinea pig proofed.

News paper lining on the floor, a small wire fence to keep them inside their enclosure, food and a hideout or two to cuddle in, and lots of running around.

Giving your guinea floor time will greatly reduce their boredom levels and will keep them happy and bouncy.

Cage requirements are very different between the two

Alright, we’ve just talked about the exercise and floor time/free roam requirements. This means that their cages need to be very large in order to keep them happy and not stressed.

For hamsters the absolute minimum is 24 x 12 inches, and about 12 inches tall. That’s 61 x 30.5 cm, and about 30.5 cm tall. That’s the minimum for a Syrian hamster, and he will do great in a larger cage than that. Dwarf hamsters can make do with smaller cages, but I’d recommend getting them a Syrian sized one as well.

The problem is that most people don’t really have the space for a cage larger than that, so they end up with the minimum.

Guinea pig cages do come in large sizes, and in fact the minimum is 110 by 60 cm/43 by 23.5 inches, for one guinea pig. Since guinea pigs should be kept in pairs you will need a cage almost double that size for both of them.

Many people opt to make their cages C&C style – corrugated plastic and cubes. It’s basically a plastic bottom cage, which can be adjusted as much as you would like, with wire mesh as a fence to keep the piggies in.

Most of these cages can be handmade, as long as you have the proper materials. They’re usually found at hardware stores, or building supply stores.

Unfortunately hamsters can’t live in a C&C cage, since the spacing is too large for them, and they will easily escape. A guinea pig is large enough that the C&C cage will keep her in.

Bedding, nests, and objects in their cage

Both hamsters and guinea pigs need toys and some basic objects in their cage. Both can live well enough with paper-based bedding, or aspen shavings.

Neither of them tolerates dust, and they have sensitive noses. Pine and cedar shavings or toys should be avoided.

A hamster will need a hideout, in which to build his nest. So does a guinea pig, but she is not as attached to her hideout as the hamster. While the hamster will build his base and make it an impenetrable fortress, the guinea pig will switch between multiple hideouts. This means that yes, she will need many places to hide.

Both the hamster and the guinea pig need wood-based objects to chew on. Their teeth always grow, even if they’re not both rodents (guinea pigs are caviidaes, or cavies for short). They need to constantly file down their teeth, in order to keep them in check and avoid dental problems.

In the same vein, both hamsters and guinea pigs need toys in their cages to stave off boredom. Bored piggies and hamsters can get restless, start chewing the bars, try to escape, and even get depressed.

They both need food bowls, simply because scatter-feeding them often ends up with a lot of food forgotten under all the bedding.

Take your schedule and daily life into account

Hamsters and guinea pigs need lots of time with their owners in order to come to trust them. Even after being tamed, they can lose that trust if you make a wrong move or scare them too much.

Remember that they are prey animals, in the end.

So in order to take your hamster or guinea pig, you need to dedicate time and effort. It could take days, it could only be a few weeks. but if you’ve got a very busy schedule, neither of them will be good for you.

If you’re working nights and you need to be awake and at home in the evening, then you will have time and patience to train and tame your hamster. Possibly the guinea pigs too.

But, hamsters sleep during the day, all day. If you’re like me and work during the day and go to bed fairly early (10 PM) you’re probably better off with the guinea pigs. They’re active during the day as well as the night, so you will end get plenty of time to spend with them.

If you’re away from home very often, and for long periods of time, then neither of these pets are suited for you. This is because they don’t get a attached to their owners as other pets, and can’t travel with you as easily. In this case a dog would be better suited, depending what king of travel you’re doing.

If you’ve got children that need changing, feeding, put to bed, a home to clean and some other errands to run, then a stationary pet like a hamster or guinea pig probably is not good for you either. Both the hamster and the guinea pig are confined to their cage, and won’t be able to follow you around.

A cat, however, will be able to come and go as she pleases and will be with you in bed, the kitchen, the bathroom, and possibly in your work bag as well.

Finally, keep in mind that guinea pigs are noisier than hamsters. The array of sounds they make, the loudness, and the frequency are all much higher. Depending on what kind of bedding you provide, you might also hear the guinea pigs moving about in their cage at night.

You’ll simply her them much more often than a hamster.

So take into account the kind of life you have, and whether you can dedicate enough time and energy to these creatures.

A word from Teddy

I hope you found what you were looking for here. Many people have a hard time choosing between us hammies and guinea pigs, but we’ve both got our good side and our bad sides. In the end it comes down to how well we’d work with your daily life.
