Albino Guinea Pig – Surprising Facts About White Cavies

albino guinea pig

Many people assume that albino guinea pig means a white guinea pig with red or pink eyes.

Guinea pigs with this coloring are widely sold and owned as pets.

But there’s actually been a long standing debate about whether they are truly albino guinea pigs at all!

Albino Guinea Pigs

This article is all about guinea pigs with white fur.

The topics we’ll cover include:

Let’s begin!

What is an Albino Guinea Pig?

All guinea pig breeds except the White Crested guinea pig are accepted into guinea pig shows with white coats.

The cute and quirky White Crested guinea pig is distinguished by a rosette of white fur on top of their head. Which obviously would get rather lost of the fur surrounding it was white as well!

It’s significant that the breed standards of the American Rabbit Breeders Association (which also oversees guinea pig breed standards) use the word ‘white’ and not ‘albino’.

That’s because few, if any white guinea pigs are actually true genetic albinos.

Let’s find out more about that now (and don’t be intimidated – it’s not too complicated!)

Albino Guinea Pig Genetics

It’s a surprising fact that all colors of guinea pig are the result of just two colors of pigment: eumelanin pigment, which is black, and pheomelanin pigment, which is red.

And genetically, white fur on guinea pigs can be the result of any one of these four things:

1. The white spotting gene

The white spotting gene is responsible for colored guinea pigs with white markings, such as White Crested guinea pigs, or pigs with Dutch markings.

These guinea pigs aren’t considered albino because they have other colors in their coat as well.

2. Color dilution genes

There are several genes which can dilute the amount of black or red pigment in a guinea pig’s coat.

They can turn black into gray, and red into cream.

One particular color dilution gene – known cryptically as Ca – reduces the amount of pigment in a guinea pig’s coat and eyes so much that they appear white with pink eyes.

Historically, this was described as an albino guinea pig.

But these days those in the know in the guinea pig community call them ‘pink-eyed white guinea pigs’ instead.

That’s because even though the amount of pigment in their coat is imperceptible, they haven’t completely lost the ability to make it.

We know this because Himalayan patterned guinea pigs, with their white coats and gray ‘points’, have also been shown to owe their white fur to the Ca gene.

3. True albinism

On the other hand, when an animal has true albinism, their body is biologically incapable of making pigment.

Which means they don’t have any color anywhere in their coat at all.

At time of writing, it’s generally thought by breeders and guinea pig fanciers that true albinism has never been recorded in guinea pigs.

4. Lethal white genes

Finally, some guinea pigs are white because they carry two copies of the gene for roan patterning.

Roan patterning is when white hairs are evenly interspersed with colored hairs in the coat.

Guinea pigs have a roan pattern when they inherit one copy of the roan gene from either parent.

If they inherit a copy from both parents, all of their hairs are white.

This is different from being white due to color dilution or true albinism.

And as the name suggests, it has very severe health consequences, which we’ll describe in more detail in the next section.

Albino Guinea Pig Health

How does albino guinea pig health compare to other guinea pigs and other pets?

On the whole, guinea pigs are pretty robust little animals.

But regardless of their color, they are all prone to some common illnesses including

All of these can be mitigated or even avoided altogether if they are carefully looked after.

Albino Guinea Pig Health Problems

White guinea pigs may be more prone to hearing loss than guinea pigs with colored coats, however studies to confirm this have produced mixed results.

Anecdotally, guinea pig breeders and show judges also report that they see more cases of abnormal bone formation inside the eyes of pink-eyed white guinea pigs.

However, it’s unclear whether this is just because it is more visible in pink-eyed animals than dark-eyed animals.

And unfortunately there’s no agreement yet on what causes it, or howbest to prevent it.

Lethal white syndrome

Remember those albino-looking guinea pigs who owe their coat to inheriting two copies of the roan gene?

Unfortunately those guinea pigs have very poor health indeed.

Symptoms of lethal white syndrome include:

  • small or missing eyes
  • partial or complete blindness
  • partial or complete deafness
  • missing or deformed teeth
  • and poor ability to properly digest food and take nutrients from it.

Lethal white guinea pigs usually die quite young from an infectious disease which they can’t fight off, or from anaesthetic for necessary surgery to correct dental problems.

Very occasionally a well cared for lethal white guinea pig might survive up to three years with a lot of care.

But this still doesn’t compare well to the average guinea pig lifespan of 4 – 8 years.

Albino Guinea Pig Temperament

Let’s turn next to albino guinea pig temperament.

Does a white guinea pig’s personality make them a better or worse pet than any other?

Guinea pigs are charming and slightly comical little characters.

If they are handled gently from a young age, they can become quite outgoing and confident with their human families.

My own guinea pigs even rush to the side of their hutch or run to greet my dog, and next door’s cat!

At the time of writing, there’s no evidence that guinea pig coat color is directly linked to personality.

However, if a white guinea pig has lost some of their hearing as a result of their coat color, they might be more nervous, and jumpy when things suddenly come into their field of vision.

Albino Guinea Pig Care

White guinea pigs have the same habitatand dietary requirements as guinea pigs of all other colors.

Since all breeds of guinea pig can have white coats, their grooming requirements will depend upon you choose a cavy with a short smooth coat, a long silky coat, or even a curly or wiry coat.

The lack of pigment in a pink-eyed white guinea pig means that they are more prone to sun damage in their eyes, and where their skin isn’t shielded by fur.

To keep them safe, always make sure that they have plenty of access to shade when they are exercising in an outdoor run.

Bear in mind that lethal white guinea pigs need an awful lot of extra care to overcome their disabilities.

If that’s a journey you wish to embark on, ask a vet or an experienced guinea pig mentor for help and advice.

Your Albino Guinea Pig

So, a truly albino guinea pig probably doesn’t exist.

But pink-eyed white guinea pigs with indiscernible amounts of pigment in their coat and eyes look exactly the same, and occur in all guinea pig breeds except the White Crested.

They are very much like their cousins with colored coats, but they may be more prone to hearing loss.

Lethal white guinea pigs look superficially similar to pink-eyed white guinea pigs, but they owe their white coat to a lethal genetic inheritance and fail to thrive.

  1. I hv a white g.p.boy a small patch on behind a light cream.
    He hears when I whistle.
    3 lbs.large balls.they touch the bottom as he walks.
    Very loving and caring to his buddy.lvs all vegg.fruit.not pickey.sleeps often with eyes closed. Has hair on said he is in good health.easy to love very curious.

Like to send pic.they are bonded sleep eat play everyday. I love them both very very much.aloha

  2. I raise white American Cavies for show. Havent had a lethal born in the 5 years I’ve had pigs.
    Their coat color doesn’t have anything to do with their personality.

  3. We have 2 white gp and 1 boar 1 male and 2 “normal” ones. Big family. All of them are super friendly and all get along.

  4. My guinea pig was pregnant and when I went to see her today I saw 5 lil creatures around her 3 of them are white with redish eyes so am still in shock they look so weird but I love them all already…🥰

  5. I have an all white guinea pig boy with red eyes. He has a spikey ridge down his back and flat forward hair. He’s lovely to stroke. He’s quite a big boy who sometime likes to cuddle.
    I always thought he was an albino pig, maybe not.
    He had 3 pups with my tortoise shell pig and she had 1 boy with his red eyes. Id love to learn more about colouring in pigs but it sounds complicated.

  6. My guinea pig who is beige and white just gave birth to 2 guinea pigs with my grey and white guinea pig.One is healthy and the other is i think a Lethal White. It’s all white and has small squinty red eyes. Is it serious?

  7. I just got a white Guinea pig with pink eyes, she was a nursing mom and appears pretty thin and there’s a lack of vitamin C and I think Calcium. Will I be able to put some weight back on to her ?

    • Carefully. And if she has a lack of vitamin c get some for her so she can fight of the bad germs. My momma piggie gave birth to two pink-eyed beauties. Only one has any issues so far

  8. Our sow just gave birth to two white puos with red eyes. Pretty sure they are twins. Fluffiest little things! They also have a gray and white sibling.

  9. I just got a new guniea pig yesterday, I love her so much! I thought she was albino because of the white fur and red eyes, how do I know if she is a lethal white though? She seems like any other guniea pig I’ve played with, only difference is her coat and eyes. I hope she doesn’t have any major problems, but I know I will give her all the love in the world until her day does come.

  10. I have a 4 year old silky white guinea with pink eyes. Marshmallow is the dominant female in the group of 4 girls. She’s super friendly and like being picked up. Loves to sit on the fresh greens. She’s larger then the others also. I am surprised she’s this old. I expected her to be a little weak and was I wrong. She’s a tank.

  11. My daughter has a solid white quinea pig double coat soft fur no color pigment anywhere. Pink ears and feet. Red eyes. Super sweet. However very sensitive skin pur’s and vibrates when you pet her. Very quiet hardly makes a peep. Seems overall pretty healthy.

  12. I have an albino Guinea pig I got a day ago and the funny part was I wasnt planning on getting him. The thing was the pet zoo employee handed him to me and when she had him he was going bezerk- but the second he felt me he was Soo calm and peaceful. So I got him mainly because I have never had a guineapig this calm in all 10 years of having Guinea pigs. He isn’t deaf or blind which is nice. But the only thing is he is still adjusting to his bigger inclosure and life. He will be introduced to my other Guinea pigs once he is finished quarantine. ( so just in case one is sick it s
    Doesn’t spread )
