When your ferret's teeth find your finger, the first question is usually: "Is it angry with me?" According to the sources, most of the time the answer is no. PDSA says ferrets may bite when they are frightened, upset, or overexcited during play; light nipping is considered normal, and a hard bite generally comes when the ferret feels threatened. In this article we pull together the causes of biting and a punishment-free approach from RSPCA Australia, PDSA, the Merck Veterinary Manual, the RSPCA, the American Ferret Association (AFA) and a veterinarian's conference paper (Teresa Bradley Bays, DVM). For holding a ferret and bites during handling, see how to hold a ferret; for the basics of reward-based training, see reward-based training for ferrets. Here we focus on the causes.

IN SHORT
  • Find the cause first: Fear, play, teething, a food smell, licking that turns into biting, or pain.
  • Young ferrets bite more: According to RSPCA Australia, ferrets usually settle down as they mature; early, positive handling reduces biting.
  • No punishment: Yelling, hitting, throwing the ferret, or scolding is not recommended by any of these sources.
  • Give a break: After a bite, end the play. Merck suggests a short time-out in the cage; RSPCA Australia suggests walking away for 2-3 minutes. Do the same thing every time.
  • If it starts suddenly: A ferret that never used to bite and suddenly does may be in pain; ask your veterinarian.

Why do ferrets bite?

RSPCA Australia says ferrets may nip or bite in these situations:

SituationWhat the source says
Frightened or accidentally hurtRSPCA Australia lists fear or accidental pain as a reason. PDSA also says a frightened ferret can bite hard
Young, teething or nursingAccording to RSPCA Australia, energetic young ferrets want to move on and explore rather than sit for quiet cuddles, and nipping can come with that
Not used to being handledRSPCA Australia says positive handling from an early age helps reduce biting
Your hand smells like foodRSPCA Australia says this is especially likely at mealtimes or when the ferret is hungry. The RSPCA also notes that ferrets have poor eyesight and may mistake a hesitantly waved finger for food
Licking youAccording to RSPCA Australia, licking can progress to biting
Play got roughMerck says ferrets can play with people as roughly as they play with other ferrets

Merck says biting is especially common in males about 3 to 4 months old that have lived mostly in a pet shop with little human contact. According to RSPCA Australia, a ferret's key socialization window runs from about 4 weeks to 10 weeks of age, and ferrets are usually sold at 6-10 weeks. So if you bring home a young ferret, biting is often a sign it hasn't yet gotten used to people rather than a "bad attitude."

Dr. Bays' paper divides biting into five types: play aggression (most common in young ferrets), fear-related, possessive, redirected and pain-induced biting. The paper only names the last three, so we won't invent definitions. But the last one matters: biting isn't always a behavior problem.

What to do when you're bitten

The sources agree on one thing: be calm, consistent and free of punishment. According to the RSPCA, shouting at or punishing a ferret doesn't work; ferrets are unlikely to understand and may become more nervous or fearful. RSPCA Australia likewise says never to yell at a ferret, hit it, or throw it away from you.

  1. Don't make your hands toys: RSPCA Australia suggests avoiding rough play and tug-of-war with your hands or body. Bays also lists avoiding rough play and tug-of-war, and keeping fingers curled.
  2. Redirect: Bays also lists redirecting the behavior among the methods.
  3. Give a break: Merck suggests putting the ferret in its cage for a brief "time-out"; RSPCA Australia suggests walking away for 2-3 minutes. In both, what matters is doing the same thing every time. According to Merck, the ferret then learns that biting isn't acceptable.
  4. Don't let it lick you: RSPCA Australia notes that licking can turn into biting.
  5. Reward calm: Bays lists giving a food treat once the ferret has calmed down.
  6. If you must move it: RSPCA Australia mentions a gentle scruff only when you really need to move the ferret or yourself away; it doesn't recommend it as an everyday hold.
The sources don't fully agree

They differ on tug games. Bays and RSPCA Australia's handling guide say to avoid tug-of-war. RSPCA Australia's enrichment page, though, lists gentle tug-of-war with a strong, tightly braided rope, chasing moving toys and hide-and-seek with a towel as play options. A way to reconcile them: use a rope or toy rather than your hand, keep games short and led by you, and end the game if the ferret gets rough.

Energy first, then cuddles

According to RSPCA Australia, ferrets are more willing to be held after they've burned off some energy. So instead of picking up an excited ferret the moment it leaves its cage, it may make sense to let it run and play first. The guide from the RSPCA's research animals department says ferrets become more amenable to handling when it is done regularly (at least daily) from an early age, and that the more often they interact with people, the more placid they usually become.

How can you tell it's about to bite?

A bite doesn't always come with a warning, but reading your ferret still helps. According to the RSPCA, an unhappy or defensive ferret may arch its back, hiss or screech with its mouth open, or snap its jaws. We cover these signals in detail in our article on ferret sounds and body language. In short: if you see them, don't force the ferret to be held; leave it alone unless safety requires otherwise.

If it starts suddenly

According to the RSPCA, hissing, biting, hiding, screaming and fleeing can mean a ferret is distressed, bored, ill or injured. The same page lists signs of pain or discomfort: reluctance to move, weight loss or loss of appetite, trembling, collapse, crying or whimpering, and teeth grinding. Bays also lists pain-induced biting as its own type.

Ask your veterinarian
  • If a ferret that never bit suddenly starts biting,
  • if the biting comes with other changes such as hiding, lethargy or not eating,
  • if the behavior has become what the RSPCA calls a "problem,"

take your ferret to your veterinarian. Don't try to guess the cause; that's the veterinarian's job.

If you were bitten: RSPCA Australia advises washing the wound thoroughly with soap and water if the skin was broken, and asking a doctor whether you need medical treatment.

Children and bites

According to Merck, ferrets may bite and scratch during play or when handled roughly, so households with young children need extra consideration. If a child and a ferret will be together, have an adult right next to them.

Keep track in Tüylüm

It can be hard to remember when your ferret started biting. If you note the day it began and anything else you noticed (appetite or sleep changes, for example) in the Complaint log, you'll have dates when you talk to your veterinarian. Show the vet collects these notes in a health summary. Your veterinarian decides which steps suit you; Tüylüm only keeps the record.

Frequently asked questions

Should I tell my ferret "no" when it bites?

The sources don't recommend verbal or physical punishment. The RSPCA says shouting doesn't work and can make a ferret more nervous. Instead, end the play, give a break, and reward calm behavior.

My ferret bit a lot as a youngster. Will it pass?

According to RSPCA Australia, young ferrets are too exploratory for quiet cuddling, and most settle down as they mature; positive handling from an early age also reduces biting. If it doesn't pass, or starts suddenly, ask your veterinarian.

My two ferrets bite each other. Is that the same thing?

No; play bites around the neck and fight bites are different. We cover this in ferrets and other pets at home. If you see a wound, separate the ferrets and show them to your veterinarian.
