Experienced sugar glider owners will be aware of the many sounds their pets make, but new owners will often be surprised to hear their cute and cuddly pet making what sounds to them like a hissing sound.

Should You Be Concerned About Hissing?

As hissing is a sound that can signify different things, it is important to be aware of your pet’s behaviors and be alert to any changes to its usual routine. If hissing is a sound that your glider makes regularly, then it is likely that this is just the sound it makes as it grooms itself.

Remember though, not all hissing sounds will be the same. Sometimes it will be a short quick hissing sound whereas at other times it might be longer and louder. If you notice a change in the sound of the hiss, look out for other signs that something is amiss.

A hissing sound that accompanies a change in stool appearance could mean the animal is constipated. If you are worried that your sugar glider is struggling to pass stools, ensure that it is getting enough fruit and water.

If the problem persists, talk to a vet, who may be able to recommend a stool softener.

Hissing in a sugar glider is rarely anything to be worried about. Most of the time it is the sound that is made when the sugar glider is grooming itself by spitting into its hands.

Over the course of my adulthood, I have had the pleasure of looking after stick insects, terrapins, an Egyptian tortoise, giant African land snails, a crested gecko, a Chilean rose tarantula, a couple of curly-haired tarantulas, and a selection of millipedes, centipedes and worms!
