Some guinea pigs are actually bred without fur. They’re called “Skinny Pigs” and occasionally they’ll have some stray strands on their faces and feet, but their bodies are largely hairless.

This one has some stray whiskers but is otherwise living the smooth life.

Born in 2009, this bunny went viral for obvious reasons. In fact, it’s hard to recognize it as a rabbit at all!

It turns out it was just a temporary condition though. After a few months, he grew up to be as soft and fluffy as the rest of his siblings.

This bald baby penguin was rejected by his parents at an aquarium in China until workers intervened.

They realized that he had a hard time absorbing nutrients so they fed him themselves until he was healthy enough to grow a feathery coat.

After that, he was welcomed back to the family.

This is Dolores. She and some other female bears at a zoo in Leipzig, Germany experienced sudden hair loss that zookeepers chalked up to a genetic defect.

While there were no other underlying health conditions, the bears experienced rashes and other skin irritations as a result of losing that protective coat.

We don’t know what became of the bears, but we certainly hope zookeepers found a way to protect them from the elements.

We didn’t even know that’s what a bear looked like under all that hair!

Hairless rats are bred intentionally and – just like hairless cats – they are called Sphinxes.

They’re often used in research labs though plenty of people like to adopt them as pets.

At least you don’t have to worry about getting fur all over you!

This is Betty. No one knows why she’s missing the hair on her body, but the animal rescuers at Foxy Lodge Rescue Center in the UK take good care of her.

She’s an otherwise healthy critter and joined her bald comrade “Baldrick” at the animal sanctuary.

Alopecia can affect animals as well as humans.

And since chimpanzees are so closely related to us, it’s even less of a surprise that the affliction could affect them.

This chimp lived at the Mysore Zoo in India and was quite the tourist attraction. But we certainly hope he wasn’t made to feel like a freak show.

Our hearts break for Oscar, a 35-year-old Moluccan cockatoo (who happens to be female despite her name) suffering from Beak and Feather Disease.

This causes her to pluck out her own feathers because they irritate her skin.

But by all accounts, she’s relatively happy bird and living the tweet life at the Humane Society of Broward County in Florida.

This beautiful breed is one of a handful of dogs that were bred to be hairless.

Unfortunately, they were simply bred this way for the convenience of humans and the genetic alteration that causes their hairlessness also has other effects, such as leading to fewer teeth.

They also need extra effort to be kept warm.

We’re glad to see this hairless raccooon is recognized by its own kind because we would have never guessed what it was.

Raccoons can develop parasitic infections (such as mange) that cause their hair to fall out.

While we don’t spot them often (since they are more susceptible to the elements and often have shorter lifespans) it’s not terribly uncommon.

Karmann is an orphaned baby wombat from Australia.

Since wombats develop in their mother’s pouches for the first 7 months of their lives, if their mothers abandon them or die, they are left alone and bald.

Karmann was rescued from the pouch of her dying mother at 3 months old and was cared for at a wildlife shelter in Melbourne.

Poor squirrel!

Unfortunately, they can lose their hair because of mites and other diseases, leaving them overexposed.

This bald female baboon appears to have alopecia.

However, it was captured on camera in the wilds of Zimbabwe, so the origin of its baldness is unknown.

Sabrina was abandoned by her mother before she stopped developing in the pouch. That means she didn’t have enough time to grow hair.

Since she was born in captivity at Serengeti-Park in Germany, humans were able to intervene and keep her warm and healthy until she fully developed.

You can tell by the name that the Hairless Syrian hamster was bred specifically to be bald.

Since they have no warm coat, owners have the be extra careful to keep them warm and help them avoid injuries to their skin.

You should only breed male hairless hamsters since the females are unable to produce milk.

Known more widely as the naked mole-rat, this burrowing rodent is native to East Africa and is always born bald.

Since they spend most of their time burrowing underground, they have very small eyes, poor sight (there’s no light down there anyway), and tiny mouths (to keep dirt out).

It can’t feel pain on its skin, so there’s no need for hair to protect it (it’s also resistant to cancer, so it doesn’t have to worry about too much sun when it’s above ground).

A woman in Pennsylvania spotted a rare hairless deer, sending photos far and wide of the unique animal.

The Pennsylvania Game Commission said they believe the deer was born that way although the animals can also contract aggressive lice infestations that leave them bald.

This baby aardvark was abandoned before it was done developing, like many hairless animals.

But we have no doubt that if someone was there to photograph it they were also there to help nurse it until it was healthy and hairy.

Eve is a black bear, despite what you might think when you first see her.

She was very young when she was found on her own, clearly separated from her mother while foraging for scraps of trash.

It’s likely that she’s suffering from a serious case of mange in this photo, but the good folks at the Fund for Animals Wildlife Center took good care of her until she was furry once again.

You can follow her ordeal here.

Eek! It’s doesn’t even look real!

That’s probably because it’s not.

As far as we can tell, this is not a living creature but either a taxidermied owl without its feathers or a model of some sort.

While experts agree that this is what an owl would look like without its feathers, this tiny dinosaur-looking creature isn’t about to come ask you for a treat any time soon.

Israeli geneticist Avigdor Cahaner created the world’s first featherless chicken at the Rehovot Agronomy Institute near Tel Aviv, Israel and people are not pleased.

The animal was literally created just to be more conveniently processed and eaten, raising questions about how we see other living creatures and our place in the world.

It’s possible that this is a photo of young Dobby, who was delivered to the Emerald Coast Wildlife Refuge in Florida after someone found her and her brother (who died shortly after being rescued) in their yard.

She suffers from alopecia, making her susceptible to the sun, injury, and predators.

There can be many causes for hair loss in squirrels, including parasites, fungi and traumatic encounters.

Earl was discovered in North Carolina and it’s been suggested that his hairlessness is the result of genetics since his tiny tail is smooth as well.

When a woman first discovered him and described him to her daughter, the girl assumed her mom had had too much wine.

The mutation that causes hairlessness in horses tends to be fatal, so they’re quite rare.

This happens most commonly in Drafts and Ahkal-Tekes.

When a horse is born hairless, you can expect to put in a lot of extra effort, especially because it can be plagued by sunburn so easily (in addition to things like fungal infections and even uncomfortable skin dryness).

The genetic defect also comes with other issues, mostly dental and intestinal, which is why these poor ponies don’t typically survive into adulthood.

While this ferret might look pretty cool to some, their hairlessness suggests they’re suffering from a fatal adrenal disease.

People are encouraged not to breed them and to take them to a vet for treatment.

If you didn’t realize monkeys looked a lot like humans before, you certainly do now!

There’s no clear story behind this photo of a bald macaque, but we’re getting serious human toddler vibes here.

You’ve almost certainly seen a Sphinx cat before and they are bred to be hairless.

There are other breeds of hairless cats as well and most of them are known for being almost dog-like in their outgoing manner.

Still, they freak some people out.

Fun fact: if they’re particularly pampered, some of them will actually grow some baby fuzz!

Baby echidnas – or spiny anteaters – are born bald, but this one appears to be an adult that’s having some issues keeping its prickly spines and fur on.

But it could be worse – it could have been the one echidna allergic to ants, which makes up 100% of the species’ diet.

We deem this the strangest hairless creature of them all!
