It reports that hedgehogs are among the loudest nocturnal animals, competing with cicadas, frogs and the caridean snapping shrimp.
It's the noise that hedgehogs make when they're out and about, busy searching for food at night. Though the noise can be surprisingly loud, a grunting, snuffling hog is perfectly happy and should be left to go about her business.
Since hedgehogs are nocturnal, they can be rather loud pets during the nighttime hours, especially if you're trying to get some rest to wake up early for work the next morning. Apart from eating, you may hear a hedgehog noisily doing laps around his cage or even utilizing a running wheel.
The huffing is often made in mating season (April to September, with May and June being the most active months). It is part of a hedgehog's courtship behaviour, where they huff and circle each other. So we can but hope for hoglets later this year.
Hedgehogs reach sexual maturity in their second year of life, and after this can breed every year. Males attempt to woo females in lengthy encounters that involve much circling, sometimes lasting hours, and rhythmic snorting and puffing. The commotion can attract rival males resulting in head-butting and chases.
Hedgehogs sleep in the day and attend to business at night. What they're doing at night is mainly eating. Hedgehogs need to eat a lot of food for their size. They will eat up to 100 beetles and other invertebrates in one night.
Huffing, Puffing, and Popping
It is quite natural for the hedgehog to be scared or nervous and the huffing and puffing noises are an attempt to scare you away. Keep in mind your hedgehog may have just been woke up during what may be for it the middle of the night.
Normal Behavior
Hedgehogs are quite active in the wild and frequently run in circles. Therefore, running laps inside the cage can be a great form of exercise. Hedgehogs can run in circles or even in a figure-eight pattern.
Routinely we expect to see hedgehogs come out in the evening around 9.30pm and go back to bed by 5am. Hedgehog living in the garden where there is food will often come out when the food arrives as they hear the clink of a bowl or the munching of another hedgehogs with their acute hearing and come out immediately.
Hedgehogs run 8-12 miles every night
While searching for food, they can run 8-12 miles every night! They often run these same distances in captivity on their wheels.
Hedgehogs are active during the night, so the best time to put out food is just after dusk, when they are starting to search for food. The Autumn and Winter months are the most important for them to find food to put on enough weight before hibernation, so always make sure you put out food at this time of year.
Night manoeuvres
Hedgehogs, too, have been the subjects of studies on the effects of ALAN. Like bats, hedgehogs avoid artificial lighting, keeping to less well-lit areas, and this could affect other behaviours.
Hedgehogs will most probably not be awake until the sun has set and the daylight is out, most of the time during the evenings. It is quite common for most hedgehogs to be sleeping between 18 to 20 hours a day.
Long-term elevated stress levels, as in humans, can have serious physiological consequences for hedgehogs. The higher level of stress shows that being handled and placed in captivity can cause long-term stress in the animals. This highlights the importance of periods of captivity being as short as possible.
8. “Anointing Themselves” Here's a behavior you won't likely see in other family pets: a hedgehog that finds a particularly exciting new scent will lick at it until he develops what is best described as a scented froth in his mouth.
A hedgehog has the strange habit of 'self anointing'; when it comes across a strong smell or taste it twists its head round and, using the tongue, covers its spines and fur in a frothy saliva - looking as thought it is covered in soap bubbles! This behaviour is quite normal but no-one knows its purpose.
A very angry/scared hedgehog in the middle of the night after close encounter with a cat (the hedgehog was not hurt, but I think the cat never ever want to get near a hedgehog again), trying to scare it off. Success, I say. Even I became a bit scared. Never heard a hedgehog scream before and, boy, was it LOUD!
Some things your pet may enjoy include balls, small cars and trucks, and stuffed animals. You can also offer him DIY toys. For instance, the cardboard tubes from toilet-paper rolls make great chew toys. (It's probably worth noting that hedgehogs seem to prefer bright colors.)
In some cases, certain species, such as hedgehogs, have unique anxiety-related behaviors that no other species exhibits.
Leaves and ground foliage have been disturbed
Hedgehogs like to rest in damp, dark places, like log piles or composts. If you have any areas like this in your garden and notice a place of disturbance, it could well have been made by a hedgehog.
Keller says, “With appropriate care and keeping, your hedgehog will live about five years, and some even live longer than eight years.” If you have any questions about hedgehogs, contact your local veterinarian.
