How Do Hedgehogs Protect Themselves? (Fighting, Fleeing, or Defense?)

When it comes to confrontation, hedgehogs generally protect themselves by curling into a ball, making noises to warn off any threats, or running away. They rarely fight back against a predator, but male hedgehogs might fight over a mate or food sources.

How Do Hedgehogs Protect Themselves?

While fleeing is usually their first option, hedgehogs curl up into a spiky ball if they can’t escape. This action protects their soft underbelly and vital organs while leaving very little except their sharp quills exposed to the outside.

When curled up, the thousands of spines or quills arranged all around their backs will raise in response to the danger. Most potential predators that attempt to press the issue will learn a harsh lesson, though it doesn’t work against everything.

Will Hedgehogs Curl Up Against All Dangers?

While hedgehogs are well known for curling up into a prickly ball in order to protect themselves from danger, they’re actually much more likely to try and run away from dangers first.

If, however, they feel they can’t outrun whatever’s chasing them or sense another danger, they’ll protect themselves in one of the best ways they know how, and it does deter many of the hedgehog’s natural predators from biting into it.

Some predators, like badgers, don’t mind getting pricked a little, though, which is why hedgehogs always try to escape first.

How Long Will a Hedgehog Stay Curled Up in a Ball?

On a given day, hedgehogs can spend three-quarters of it curled up in a ball for one reason or another. That’s because, on top of external threats, a hedgehog usually curls up when it sleeps. Being nocturnal and only active for around 6 hours a day. This leaves a lot of ball time.

We can only hope that the hedgehog is comfortable in this position!

Why Would a Pet Hedgehog Curl Up Into a Ball?

As mentioned earlier, there are a number of reasons besides immediate danger that a hedgehog will curl up. Stress, sudden movements, or strong emotions can contribute to the act as well as temperature shifts.

Aside from sleeping, pet hedgehogs have been known to react instinctively to things that they may feel threatened by even if it’s just someone getting up or being startled. The most common one is due to temperature or hibernation.

When they’re cold, hedgehogs curl up because the layer between their body and the quills acts as a sort of insulation. Still, most pet hedgehogs shouldn’t hibernate or have cause to do so.

With all of that being said, if you’re a hedgehog owner don’t be surprised if yours never curls up. (Besides from when it’s sleeping.) In fact, it’s a good thing because it means your hedgehog feels relaxed and safe.

Do Hedgehogs Make Any Defensive Noises?

When facing a predator or another threat, hedgehogs are known to elicit a hissing sound if they feel threatened. They’ll often make this sound while being rolled up in a ball.

You might see it combine the noise with vibrating its quills, which is all to ward off the predator.

Are Hedgehogs’ Fighting Noises Different From Their Defensive Noises?

Hedgehogs make a surprising amount of noise for such small creatures and, while they rarely do when they fight they let loose something between a scream and a squeal.

Unfortunately, the latter means they’re feeling intense fear so you might need to intervene.

The difference is that fighting sounds tend to be higher pitched than the grunts, huffs, and hissing of defensive hedgehogs. That’s because the defensive sounds are warnings while the fighting sounds are meant to incite fear in the other animal.

Do Hedgehogs Fight One Another?

Absolutely, with the three most common reasons being territorial quarrels, food sources, and mating rights.

Male hedgehogs will fight over a mate during mating season, which is between the Spring and Summer months.

If a source of food is limited, hedgehogs will battle it out over resources. Between those two reasons, territoriality is generally a cause because more hedgehogs in a given area can create strife.

What About Other Small Animals Like Rats, Cats, Dogs, and Foxes?

While hedgehogs are meat-eaters, they’re not likely to attack other animals unless they have absolutely no food available. Usually, they’ll feed on carrion to sustain themselves.

When hedgehogs get attacked by predators, they generally try to escape. Hedgehogs are simply not good at fighting other animals.

If the hedgehog is cornered, or too slow to escape the aggressor, it will try to curl up into a ball and hope for its spikes to protect it until the predator gets bored and goes away. Many of the hedgehog’s most common predators, like foxes and badgers don’t mind the spikes, however.

How Do Hedgehogs Fight Each Other?

When two hedgehogs fight, it mostly happens by pushing and puffing each other around a bit. They lower their heads and raise their quills to ram sideways into one another.

When they do this, they’ll make aggressive grunts and squeals as mentioned before.

And while this doesn’t sound particularly dangerous, hedgehogs can hurt themselves doing this because of the sharp spikes that are hard to avoid.

Owners of pet hedgehogs might note that hedgehogs might nip or bite you if you, but it’s not from a place of anger. It’s how they learn about their surroundings and people.

Why Do Hedgehogs Fight?

Hedgehogs are not instinctively territorial like many animal species, but if you put two male hedgehogs in the same space they might fight over food or a female.

It doesn’t help that hedgehogs are naturally solitary, so more than one can create stress.

Another way that they differ as a species is that hedgehogs don’t fight to protect their young from predators. They’ll simply run, leaving their young to fend for themselves.

Do Female Hedgehogs Fight or is it a Male Thing?

Males of most species fight more and hedgehogs are no different. While not territorial, they’ll fight for food or mating interests.

Female hedgehogs, on the other hand, aren’t known to be violent at all. Since they’re not protective of their young, they really don’t fight over anything.

Do Hedgehogs Fight to the Death?

The quick answer is no because hedgehogs don’t have the means to fight to the death.

With the way that they fight each other involving bashing their quills against one another, no real damage can be dealt to anything vital.

They might have a few scratches or cuts, but mostly the only thing wounded is their pride after a fight. If you hear a shrill sound, you might want to intervene but otherwise, there’s no reason to worry.

How to Stop Hedgehogs From Fighting

Hedgehogs can have a favorite object or something sentimental, so space that out from any other hedgehogs.

Make sure there’s enough food and maybe try separating food dishes. You’ll have the most trouble avoiding conflict during mating season.

With all of that said, sometimes hedgehogs will ignore their own food dish if they smell another hedgehog nearby. If they do start fighting, don’t grab them because of their quills. Just try to nudge them away from each other with a broom or long object if you have to get involved.

How Can I Tell the Difference Between Hedgehogs Fighting and Mating?

Both situations involve a noisy hedgehog, but there are distinct differences in the sounds they make for each act.

Fighting gets hissing and grunting while mating or hedgehogs in search of a mate will emit a clicking or puffing sound.

What Can I Do to Protect Hedgehogs From Dogs, Foxes, and Cats?

The good news is that most domestic pets won’t harm your hedgehog, especially if they’ve become familiar with the pointy end of a quill.

If you’re worried about an external predator, you can warn your hedgehog with an outside light.

Hedgehogs are creatures of routine and habit, so they have a specific schedule. If you plan to let your pet outside, you can flip the light on a few minutes before to let your hedgehog know. 

As far as foxes go, you can try cutting a small hole into your fence large enough for the hedgehog to squeeze through if it has to escape.

How Do Hedgehogs Protect Their Young?

Female hedgehogs aren’t naturally protective of their offspring. As a balance, baby hogs begin to venture out for food at only 3 or 4 weeks old. The mother will accompany them on these trips, but a week or so later the young are on their own.


Do Hedgehogs Curl Up When They Die?

This is a yes and no answer, because hedgehogs can curl up when they die but they’re also prone to “splatting” behavior upon death which is lying flat with their limbs outstretched. It can be even more confusing because hibernating hedgehogs may seem like they’re not breathing.

The “splatting” is actually more common for a dead or dying hedgehog because one of the biggest causes of death is heatstroke, so they’ll have less energy to curl up, and lying flat puts their stomach in contact with a cool surface.

Do Hedgehogs Play Dead?

Some small animals are known to play dead, like groundhogs or opossums, but the hedgehog isn’t one of them. The closest they come is curling up and remaining immobile, but this is more of a defensive tactic than simply not moving.
