Do pygmy hedgehogs make sounds to “talk”? Here’s how they communicate with humans

Have you ever wondered if pygmy hedgehogs make sounds to talk with us? Although silent by nature, these small mammals can emit hisses, clicks and even growls to express emotions and needs.

These sounds are part of their communication and are forms of interaction that can bring you and your pet even closer.

Understanding how hedgehogs communicate can help you decipher their emotional states and provide more appropriate care. They are solitary but sensitive animals, and each sound carries a message—from comfort to a request for attention.

How and why pygmy hedgehogs make sounds

Studies indicate that the atelerix albiventris, the African pygmy hedgehog, has hearing tuned to capture frequencies between 2 and 46 kHz — similar to the auditory perception of other domestic mammals. This suggests that the sounds they emit are important for social interaction and risk recognition.

These animals make soft chirps when comfortable, “stretch” their breath when exploring, and can produce high-pitched, popping, clicking sounds when excited or stressed, especially in defensive situations.

In freedom, these sounds coordinate movements between males and females, but in captivity they serve to interact with the owner.

Common sounds and their meanings

Short, purring sounds usually occur when your pet is relaxed, exploring the environment, or being gently touched. Dry, repetitive clicks can be a warning sign — as if your pet is saying, “I’m here, watch.”

In cases of fear or discomfort, these sounds can evolve into growls and high-pitched squeals. These are clear signs that he wants to be left alone.

If your hedgehog regularly makes these sounds when you handle him, it's best to take a step back and let him get used to it in his own time.

Sound relationship between pet and guardian

When you speak softly to your pet, he may respond with small clicks or squeaks. This sound is not a word, but it is a response—a clear, intimate nod. Over time, he may associate your voice with safety and may even respond more frequently.

Additionally, many owners notice that hedgehogs reduce the volume of their sounds when there is prolonged physical contact. This may indicate comfort, a kind of “silent conversation” between species.

Practical example: interaction in affection sessions

Owner Júlia says that her hedgehog, Pipoca, would make a short sound – similar to a dry “tic” – when she gently touched her finger to his back.

Over time, this sound became a kind of greeting, and she began to use this interaction to reinforce the bond.

In another case, Chirol, a hedgehog accustomed to loud noises, would make continuous clicking noises after visits to the vet. When the auditory stimulus in the environment was reduced, the behavior disappeared — showing that the sound was saying, “This is stressing me out.”

Reliable studies and sources

A study of the Journal of Comparative Physiology on hearing in pygmy hedgehogs shows that they are able to locate sounds with precision — an ability linked to the way they emit auditory signals.

Additionally, publications such as OnTheEdge Conservation explain exactly what types of sound communication this species uses: grunts, chirps, clicks, and squeaks used in specific situations — comfort, defense, excitement.

Different sounds, different personalities

Not every hedgehog will make sounds the same way — and that’s not a sign that something’s wrong. Some are naturally more expressive, while others prefer silence.

Personality counts for a lot. A more sociable hedgehog may chirp whenever it notices movement nearby, while a more shy one will only show signs of aggression in specific situations. The secret lies in constant observation.

Recognizing your pet’s individual pattern of sound behavior allows you to differentiate between a normal sound and a possible sign of stress. Over the course of a day, you can notice what is typical of your pet and what is new or unusual. This sensitivity is essential for a healthy coexistence.

When sounds become a warning sign

Although they may seem just curious, some sounds emitted frequently or more intensely can indicate discomfort or even pain.

A high-pitched, repeated squeak when touched, for example, should not be ignored. Likewise, a sudden, complete silence in an animal that used to be very vocal can also be a sign.

Sudden changes in the frequency or intensity of sounds require attention. This is a change in the sound behavior that is not typical for that pet. In these cases, it is best to note when it started, what was happening in the environment and if there were any other physical symptoms.

The role of environment in communication

The space in which a hedgehog lives greatly influences the way it communicates. A calm environment, with familiar smells and little noise, favors softer sounds and positive interactions.

Very busy spaces, with constant noise or intense lighting, can generate alert or stress sounds.

A pet that squeaks whenever the TV is on or makes loud noises when there are lots of guests at home may be reacting to the environment. Making the space more peaceful, with hiding places and comfort zones, helps the animal use sounds to express well-being — not defense.

Conclusion

You pygmy hedgehogs make sounds to talk emotional vehicles and needs. These noises are channels of expression as rich as those of dogs and cats. When we perceive these signals — and respond calmly — we build a truer and safer relationship.

Listening to your pet goes beyond listening with your ears: it means paying attention to the sounds, the contexts, and what your pet is trying to say through them. And then speaking back, with presence and care.

Frequently asked questions about sound communication in pygmy hedgehogs

1. Do pygmy hedgehogs make sounds while sleeping?
Yes. Short wheezes or purrs during sleep usually indicate comfort. Squeaks can be a reflection of dreams or discomfort.

2. Is loud noise bad for them?
Yes. Loud, sudden sounds can cause stress and growling. Keep environments quiet, especially during rest.

3. Do they imitate human sounds?
Not like parrots, but they can respond to familiar sound stimuli with short clicks, signaling recognition.

4. How do I respond when my pet makes a sound?
Speak softly back, offer rest or affection. Avoid sudden movements and loud sounds in return.

5. Sounds indicating pain or illness?
Constant, high-pitched squealing, especially when handling your pet, may indicate pain. In this case, take your pet to a specialized veterinarian.
