Ferret sounds: dooking, hissing and what they mean

What sounds do ferrets make and what do they mean?

Ferrets make a small set of sounds, and most of them happen during play. The famous one is dooking. The rest are warnings, complaints or alarms. Ferrets also spend most of the day asleep, so a quiet ferret is usually just a sleeping one. As with any pet, read the sound with the body: a hiss from a ferret bouncing sideways is not the same as a hiss from one backed into a corner.

The table draws on Chewy's vet-reviewed guide, the MSD Vet Manual, The Vet Desk, Unusual Pet Vets and PetMD. Our guide to ferret behaviour and body language covers the postures that go with these sounds.

What is ferret dooking?

Dooking is the happy sound of a ferret having fun. Chewy's vet-reviewed guide describes it as a chuckle-like sound, sometimes like clucking, linked with play or excitement. You will hear it most when a ferret first comes out to play, while chasing a toy or another ferret, and during the war dance.

The war dance looks alarming the first time: the ferret hops sideways, arches and twists its back, bounces off things and dooks the whole time. Chewy's guide is clear that despite the name it is playful behaviour and a sign of an excited ferret. The MSD Vet Manual also says that when first let out, ferrets may run, jump, twist in the air and crash into household objects, and calls this a sign of high spirits and good health. Our guide to ferret playtime has ideas for games that bring it out.

Why is my ferret hissing?

A hiss usually means the ferret is annoyed, scared or uncomfortable. Chewy's vet-reviewed guide says hissing can be a reaction to fear, discomfort or annoyance, and that it can be a warning or can happen during play, so you need to check the rest of the body.

Sources do not fully agree here. The Vet Desk's vet-reviewed guide on hissing says it is always a sign of fear or discomfort and a warning of possible aggression, and lists anger, pain, feeling threatened, fear and hormones as causes. It notes that unneutered ferrets can become more irritable around sexual maturity, roughly 4 to 8 months old. We would follow the more careful reading: treat any hiss as a request for space unless the ferret is clearly mid-game and keeps coming back for more.

• Play hissing: bouncy body, dooking, war dancing, comes straight back.
• Warning hissing: puffed-up tail, backing away, arched and still, may nip.
• Burgess says a nip with hissing and backing away means a frightened ferret that needs space.
• The Vet Desk's guide suggests a vet check if a ferret hisses often, as pain can be a cause.

Why did my ferret screech or scream?

A screech or scream means fear, pain or distress. Chewy's vet-reviewed guide lists screaming among the sounds of fear, pain or distress. The MSD Vet Manual describes young ferrets that are startled hunching their back, puffing out their fur and screeching, and says older ferrets do this only when truly under attack.

1. Get them out of danger. Separate ferrets that are fighting, or remove whatever frightened or trapped them. The Vet Desk's vet-reviewed guide suggests thick gloves or layers if you must handle an upset ferret, as their teeth and claws are sharp.
2. Check for injury. Look for bites, limping, bleeding or a trapped foot or claw.
3. Let them calm down. Put them in a quiet, dark spot with a familiar sleeping sack or hammock.
4. Ring a vet if anything is wrong. Any wound, limp, or a ferret that is not back to normal within a short time needs a vet the same day.

Why is my ferret squeaking or squealing?

Most squeaks are part of play. The Vet Desk describes ferret squeaks as less of a squeak and more of a giggle, close to dooking, and says to keep an eye on it if it gets louder or more frequent. Squeaking is poorly covered by vets and charities, so we found no source that pins down every kind. A long, loud squeal that does not stop is closer to a screech, which Chewy's vet-reviewed guide links with fear, pain or distress. If play keeps ending in squeals and one ferret is always on the losing side, give them breaks and check for bite wounds.

Why is my ferret whimpering or whining?

Whimpering is a sign of fear, anxiety, discomfort or pain, according to Chewy's vet-reviewed guide. The Vet Desk's guide separates the two: it says whimpering often means a ferret wants attention, while whining that is more frequent and insistent usually means a sick or uncomfortable ferret that needs a vet as soon as possible. That second guide is not vet reviewed, so we would treat any whimper or whine that carries on, or comes with other changes, as a reason to see a vet. Our ferret health guide lists the other signs to check.

Do ferrets bark or grind their teeth?

Some do, but neither sound is well covered by vets. The Vet Desk describes a ferret bark as more like a loud chirp than a woof, usually when the ferret is very excited. It also says teeth grinding during or just after a meal is likely just clearing food, but grinding at other times can mean pain and is worth a vet visit. We found no charity or vet-reviewed source on either, so read them with the body, and take teeth grinding with a hunched or quiet ferret seriously.

Which ferret noises mean you should see a vet?

Breathing noises, a screech you cannot explain, ongoing whining, and teeth grinding away from meals. Unusual Pet Vets, an exotic pet practice, says occasional sneezing is normal in ferrets, but sneezing with discharge such as pus or blood, or several sneezing fits a day, may mean something more serious. It says coughing is abnormal if it happens several times a day, and that wheezing, a high whistle-like sound, is rarely normal in ferrets. It also notes ferrets can catch human flu.

PetMD's vet-reviewed guide lists open-mouth breathing, bluish gums and severe lethargy as emergency signs that need immediate vet care, and laboured breathing or reduced appetite as reasons to contact a vet promptly.

Why is my ferret so quiet?

Most of the time, because it is asleep. The MSD Vet Manual says ferrets sleep up to 18 hours a day, and that young ferrets sleep so deeply they can be difficult to wake, even when pinched or patted on the chest. A ferret with a warm, moist pink mouth that is breathing slowly and regularly is simply sound asleep. The same source says shaking and shivering on waking is normal. The Vet Desk also notes some ferrets are just quieter than others.

Quiet matters when it is new. A ferret that stops dooking at playtime, sleeps far more than usual, eats less, or seems weak or wobbly once awake may be unwell. Burgess's advice is to consult a vet whenever you have any concern about your ferret's health, and PetMD's vet-reviewed guide treats severe lethargy as an emergency.
