Chinchilla vs Guinea Pig: Which Pet Fits Your Lifestyle?

You want a small, furry pet but can’t decide between a chinchilla and a guinea pig. They look similar, but they’re very different in lifespan, temperament, and daily care.

Chinchillas can live up to 20 years, while guinea pigs top out around 8. Guinea pigs are more cuddly and better with kids, but chinchillas are more fragile and need dust baths instead of water.

Here’s a full comparison to help you pick the right pet.

General Differences

One of the biggest differences between chinchillas and guinea pigs is their temperament.

Chinchillas are curious and energetic. They’ll explore everything around them, which is why mischief comes with the territory.

Guinea pigs lean docile. They’re social animals with distinct personalities that show up quickly once they’re comfortable.

Guinea pigs know you’re their source of food, so they’ll follow you around. If you’re curious about their activity patterns, check out our guide on whether guinea pigs are nocturnal.

Chinchilla History

Ancestors of chinchillas in captivity are those 13 original chinchillas brought to the United States in 1927.

Originally, they were bred for the fur trade.

Fur traders eventually noticed how cute they were and started keeping them as pets instead.

Wild chinchillas live in high and cool areas in the Chilean Andes mountains.

That’s why chinchillas can’t tolerate temperatures above 26 degrees Celsius.

If exposed to temperatures over 26 degrees Celsius or 80 degrees Fahrenheit, they might suffer a fatal heatstroke.

Chinchillas can’t tolerate dampness either. Over forty percent humidity can be deadly for them.

They can be challenging to maintain if you live in an area that isn’t similar to their wild climate.

Guinea Pig History

Although chinchillas are a recent addition to the “pocket pet” marketplace, guinea pigs have been there for much longer.

Guinea pigs were first domesticated between 5000 and 900 B.C.

In the traditional Chilean culture, they have a specific name for them, “cuy.”

In ancient Chilean Andean culture, guinea pigs were important for their meat, fur, and medical value.

Guinea pigs later became widely used as laboratory animals in modern western medicine. That’s where the phrase “being a guinea pig” comes from.

Guinea pigs are hardwired for group living. A solo piggy won’t thrive.

They’re neither nocturnal nor diurnal animals, but crepuscular.

That means that guinea pigs are active at dawn and dusk and sleep for brief periods during the rest of the day (and night).

Guinea pigs can tolerate temperatures between 65 to 75 degrees Fahrenheit and they’re comparatively more tolerant to cold than heat.

Like chinchillas, guinea pigs can’t tolerate excessive dampness.

Chinchilla vs. Guinea Pig Health

If you properly take care of these small animals, chinchillas can live up to 20 years.

An adult chinchilla usually weighs between 0.88 to 1.3 pounds.

Females are slightly heavier than males.

An adult ranges from 8 to 12 inches.

A guinea pig can live up to 8 years.

Sometimes they can live longer, depending on the care they receive and their individual characteristics.

The weight of an adult guinea pig ranges from 1.5 to 2.6 pounds. Guinea pigs are also between 8 and 12 inches long.

Chinchilla vs. Guinea Pig Care

Both species are strict herbivores. Plant-based food only.

Their digestive tracts are built to process fiber, and they need plenty of it to stay healthy.

Chinchillas have a habit of chewing, so you’ll need a wired cage with a smooth bottom. They love to hop, climb, and jump, so provide at least two square feet of floor space and sufficient height for hopping.

Chinchillas also love to remain out of sight and hide to rest. You should provide wood or pumice stone for teething since they can’t live without chewing.

Guinea pigs drink water frequently, so they need a constant supply of clean water.

Their bodies can’t synthesize vitamin C on their own. That makes foods high in vitamin C a must in their daily diet.

If you have a guinea pig as a pet, make sure the cage bottom is smooth. Wire or mesh bottoms will hurt a guinea’s soft and sensitive feet.

Your guinea pig also needs at least 7 square feet of personal floor space. Take a look at some guinea pig cages for small spaces if room is tight.

Chinchilla vs. Guinea Pig Special Requirements

Since chinchillas have very thick fur and don’t like moisture, they don’t take baths in water. They need a special dust powder, usually daily.

Always make sure your chinchilla stays clean and dry. Otherwise, their fur may grow fungus.

Both guinea pigs and chinchillas need to chew continuously. If they don’t, their teeth will grow abnormally and can cause injuries.

Chinchillas are very fragile, so cushion them when you pick them up. Never try to hold a chinchilla’s tail.

Because of their nervous temperament, they need consistency in their daily routine. If that consistency is missing, they may get ill.

The ancestors of guinea pigs are burrowing rodents, so they need access to a safe hiding space.

To keep a guinea’s feet healthy, trim their nails regularly. If you choose a guinea with long fur, you’ll also need to prevent matting by grooming weekly.

Chinchilla vs. Guinea Pig Cost

The cost of a chinchilla, as well as a guinea pig, depends on where you buy it.

Mostly, guinea pigs are cheaper because they’re common pets and are widely available in pet stores.

You’ll rarely find chinchillas in pet stores, and they’re more expensive.

If you get a chinchilla or a guinea pig from a shelter, you can sometimes get them without paying a penny.

Chinchilla vs. Guinea Pig Smell

Compared to guinea pigs, chinchillas smell a lot less.

They’re clean in every way, and they’re a little easier to care for.

Most rodents develop odor in their fur.

However, despite their excellent fur, chinchillas won’t develop any odor in their fur.

One plus point of chinchillas over other rodents is that they produce solid and dry poop, which hardly smells.

And, also, a chinchilla pees less compared to other rodents, but that greatly depends on the amount of water it drinks.

Guinea pigs produce a lot more odor. They poop and pee everywhere, so you have to put in extra effort to keep their cages clean and dry.

If waste builds up on the cage lining, it develops a foul smell. Learn more about controlling guinea pig odor.

Chinchilla vs. Guinea Pig Life Expectancy

Chinchillas live longer than guineas, both in the wild and in captivity.

Chinchillas = 15-30 years

Guinea pigs = 8 years

The average lifespan of a chinchilla in the wild habitat is about eight years.

This is because they often encounter predators.

In contrast, chinchillas live longer as pets.

If you buy a baby chinchilla, you can expect it to live for at least 15 to 20 years.

In contrast, guinea pigs have a shorter lifespan.

The maximum lifespan that you can expect with good care for a guinea is around eight years.

If you want a pet that remains with you for longer, a chinchilla is a perfect choice.

However, be aware that guinea pigs also need someone to love them and take care of them!

Regardless of how long a pet lives, it’s never easy to say goodbye.

Chinchilla vs. Guinea Pig Size

Most people wonder whether chinchillas are bigger than guinea pigs.

The two common types of chinchillas in households are both larger than guinea pigs.

Chinchilla = 11-19in (short-tail), 8 to 15in (long-tail)

Guinea pigs= 8in

Long-tail chinchillas roughly weigh 400-450g, while short-tailed chinchillas are much heavier and weigh about 1.1-1.4kg.

Guinea pigs are shorter compared to chinchillas.

They hardly reach seven to eight inches.

But as far as weight, guinea pigs are heavier.

Just like short-tailed chinchillas, they weigh around 0.7 to 1.2kg.

Chinchilla vs. Guinea Pig Intelligence

Neither chinchillas nor guinea pigs are super-intelligent.

It depends on what you mean by “intelligence.” If you expect a rodent to be really witty, then no, neither chinchillas nor guinea pigs fit the bill.

That said, both types of rodents love to play and learn new things.

After proper training, a chinchilla can do some basic things, such as:

• Returning to its cage
• Lying down
• Standing up
• Moving in a circle
• Potty training

So, it should be clear that if you need a pet that can learn many commands and impress you with its intelligence, then none of these rodents are for you.

Chinchilla vs. Guinea Pig Training

We can train chinchillas to do some basic things such as returning to their cage when playtime is over, lying down, or moving in a circle.

We can also teach them to come when called.

Before training starts, it’s necessary for a chinchilla to trust its trainer. Training a chinchilla isn’t a simple task by any means.

It requires a lot of time and patience.

Treats work best while training chinchillas.

Guinea pigs are comparatively difficult to train.

However, keep in mind that they’re really smart and enjoy learning new things.

We can also train them to do a few similar things, just like we can train chinchillas.

Like chinchillas, we also train guinea pigs best when we offer them treats.

Chinchilla vs. Guinea Pig Diet

Both chinchillas and guinea pigs eat a lot of hay.

Hay comprises 4/5ths or 80% of a chinchillas diet.

If you are a new owner of a chinchilla, you might be surprised by how it survives on low nutrient hay.

That’s surprising considering how other pets need various foods to meet their mineral and vitamin requirements.

Because hay is less nutritious, chinchillas have to eat a lot of it to survive. This may look like overeating if you’re a new owner, but it’s completely normal.

Guinea pigs’ primary source of food is also hay.

But they also like to eat leafy greens.

Most people think guineas need more variety in their snacks, like sunflower seeds and nuts.

Chinchilla Veterinary Care

Fractures

Chinchillas are very active throughout their life, and mostly they recover quickly from minor physical injuries.

Fractures are problematic because chinchillas love to sit on their hind legs and eat with their front paws.

So, most types of fractures would disturb their regular eating habits.

Convulsions

Some breeders claim that chinchillas sometimes get convulsions.

First, you should know why convulsion occurs.

There could be any of the following reasons behind convulsions:

• Hemorrhage
• Vitamin or dietary deficiency
• Nervous system injury

Besides these reasons, some chinchillas might get convulsions when they feel stressed because of other chinchillas getting food first.

To prevent convulsions, there are several things a vet can use:

• Vitamin B
• Cardiac medication or a calcium injection
• Infectious Diseases

A list of infectious diseases prevalent in chinchillas is:

• Listeriosis
• Pasteurella Infections
• Pseudomonas aeruginosa infections
• Respiratory tract infections
• GIT problems (constipation or diarrhea)
• Mental Health

Chinchillas could get easily distressed and unhappy if:

• Their breeding mate changed in the breeding season
• There’s a change of diet
• A prevalent sign of a stressed chinchilla is fur chewing, either their own or of their cage mates

Guinea Pig Veterinary Care

Some signs that a guinea pig is sick are:

• Loss of appetite
• Weight loss
• An abnormal walk
• Hunched posture
• Enormous belly
• Change in the consistency of the hair coat
• Difficulty breathing
• Decreased energy
• Not responding to noises or touch

Guinea pigs suffer from a lot of health disorders such as:

• Vitamin C deficiency
• Respiratory problems
• Abscesses
• Mange
• Pododermatitis
• Dental Problems
• Heatstroke
• Ringworm
• Diabetes
• Trauma or Poisoning

Cuddling Chinchillas/Guinea Pigs

Guinea pigs win this one hands down.

If they trust you, piggies will happily sit on your lap and let you hold them. They genuinely enjoy physical contact.

Chinchillas are a different story. They’re incredibly soft but also fragile.

Their ribcage is part cartilage and part bone, unlike most animals with fully bony ribcages.

That doesn’t mean you can’t cuddle at all with your chinchilla, though.

You can move your fingers through their remarkable fur.

You can also hug them, but keep in mind their softness and fragile bodies.

In contrast, guineas are stronger than chinchillas.

You can hug them, stroke them, and hold them in your lap.

Besides, guinea pigs love to cuddle and they’re looking for a strong bond with their owners.

Can Chinchillas and Guinea Pigs Live Together?

No. They can’t and shouldn’t share a cage.

Putting them together usually leads to fighting because they don’t get along.

Both have sharp teeth that can cause real injuries. Conflict erupts over food, water, hay, and space.

Every animal has a natural drive to gather resources like food and water. Any other animal who takes those resources is a threat.

They also can’t live together because of their different needs.

Chinchillas love to live in a cooler environment compared to guinea pigs.

Chinchillas also prefer to stay clean and dry, while guinea pigs are careless.

Piggies are messy eaters and they tend to flip their water bowls, so you’ll need to take care of their bedding and clean their cage quite often.

Can Chinchillas Eat Guinea Pig Food?

Although the primary diet of both species is similar, they still differ in their needs. As discussed, guinea pigs can’t synthesize vitamin C on their own, so their food must contain vitamin C supplementation.

Chinchillas and other pet animals don’t need vitamin C in their diet. Manufacturers prepare separate pelleted food blends for each species, which you can easily buy at pet stores.

It’s not a good idea to share their food. Whichever pet you choose, you’ll be happiest if you spend a lot of time with them.

Should I Get a Guinea Pig or Chinchilla For My Kids?

No matter how fantastic a chinchilla is, when deciding on a better pet for younger kids, then a guinea pig is the only option.

There are several reasons for such a choice:

• A guinea pig is much less fragile and not prone to injury
• It won’t shed out a huge clump of fur
• It won’t bite if accidentally mishandled
• Guinea pigs are more social
• They’re very cuddly pets
• They’re brilliant and slightly trainable

Which Pet is Easier to Maintain, a Chinchilla or Guinea pig?

Which pet is easier to care for isn’t something guinea pigs and chinchilla owners debate.

It’s very tough to choose between them.

The only thing you can do is make a choice based on your likeness or requirements.

The following list of pros and cons could become easier for you and your family to decide on a pet for your home.

Should I Get a Chinchilla?

If you are a first-time pet owner, then no, you shouldn’t get a chinchilla.

They’re exotic pets and need more care and cleanliness. As a new rodent owner, you should start with a guinea pig to gain experience with pet care routines and the challenges owners face.

Although a chinchilla can be a great pet, it’s also significantly more challenging. It’s harder to find veterinary care for chinchillas too, since most vets are more experienced with guinea pigs.

Chinchilla makes an excellent pet because of the following reasons:

• They have a longer life span compared to guinea pigs
• Don’t make much noise
• They’re odorless
• They can live alone
• Doesn’t need vaccinations
• Healthier compared to piggies

A chinchilla may not be the pet for you because:

• They’re expensive
• Active at dawn and dusk (Crepuscular)
• It could bite if mishandled
• They need a controlled environment in terms of humidity and temperature

Should I Get a Guinea Pig or a Chinchilla?

Guinea pigs are a perfect choice if you have younger children. Kids are usually careless, and unlike chinchillas, guinea pigs can handle slight mishandling.

Piggies are sturdy, while chinchillas are delicate and fragile. One important thing to know: guinea pigs and chinchillas should never live together.

Don’t let these small animals share a cage with other rodents either. They all have unique needs, and it’s not just that they won’t get along.

What Are The Pros and Cons Of Owning a Guinea Pig?

There are several pros and cons if you are thinking about buying a guinea pig:

Pros of getting a guinea pig include:

• You can pick them up easily
• They’re very social
• They rarely bite
• They’re not expensive
• They’re easy to care for
• They love to cuddle

Some of the reasons why you might not consider getting a guinea pig:

• Shorter life span
• They pee a lot and have an odor
• They’re crepuscular (active at dawn and dusk)
• They need a companion

Final Thoughts

Both chinchillas and guinea pigs make wonderful companions, but they need very different care. Your choice should depend on your experience level, living conditions, and how long you’re ready to commit to a pet.

If you already have guinea pig experience, a chinchilla will feel more manageable. Whichever pet you pick, you’ll enjoy every moment you spend together.
