Sugar glider hissing can mean very different things depending on when it happens. A short hiss during play or while exploring is usually just communication. Hissing while straining to poop or pee, though, can signal constipation, a blockage or a urinary problem that needs a vet. Paying attention to the context is the key to knowing whether to relax or call your exotics vet.
At SunCoast Sugar Gliders we've listened to gliders since 1999, and new owners often call us worried about hissing. Here's how to read the sound, including what it means during bonding.
Normal Hissing: Communication and Play
Gliders have a surprising vocabulary. Short hissing or sneeze-like sounds can happen when gliders:
- Play, chase or wrestle with a cagemate
- Explore something new
- Groom themselves (they often clean their hands and face with a quick sneeze-like sound)
- Feel mildly annoyed
These sounds are usually brief and come with otherwise normal behavior. If your glider is eating, active and pooping normally, occasional hissing is rarely a concern.
Hissing That Needs Attention
Hissing while pooping
If your glider hisses or strains while trying to defecate, it may be constipated or have an intestinal blockage. Other signs include small, hard or no droppings, a bloated belly and reduced appetite.
Hissing while urinating
Straining or hissing during urination can be a sign of a urinary tract infection, bladder stones or another problem. Look for blood in urine, frequent attempts or a wet, irritated rear.
What to do
Call your exotics vet. Blockages and urinary problems can become serious quickly in a small animal. Don't try home remedies such as oils or laxatives unless your vet tells you to. Our guide to sick sugar glider symptoms covers related warning signs.
Hissing and Crabbing During Bonding
New gliders often hiss or crab when they're unsure of you. Crabbing is the loud, buzzing "leave me alone" sound. Read about it in our guide to sugar glider crabbing.
When a glider hisses or crabs during bonding:
- Stay calm. Move slowly and speak softly.
- Avoid accidentally rewarding the warning. If you always pull away the instant your glider fusses, it may learn that hissing makes people leave. Instead, pause calmly, let it smell you, then continue gently.
- Keep sessions short and positive. End on a good note with a treat such as a piece of Happy Glider Fruity.
- Use a bonding pouch during the day so your glider gets used to your scent.
