Ferret Health

Just like a good marriage, please understand that if you get a ferret — or ferrets — they are with you for better and for worse!

They will shower you with love and affection but you, in return, must promise to look after them in the good times, and in the bad … which means your wallet might look pretty anorexic after a bout of “bad times”.

One thing you’ll discover if you have ferrets – when they get sick, it happens very quickly, and you have to be prepared to rush them to the vet immediately.

And it is VITAL that the vet is ferret knowledgeable, so please make sure you find one in your area whom you’re happy with. If you don’t have access to a ferret vet, then you can always click the link at the top of the page.

However, if you take the time to really get to know your ferret/s well, then you’ll be instantly aware of any change in their behavior or if they suddenly appear off-color, and be able to whisk them down to the vet for prompt treatment.

There are a lot of diseases which ferrets can suffer from, including a number of cancers and they have been listed in the Medical Information page. I’ve also linked the headings below which have more information in the Medical Information page for easy reference.

Things you don’t have to worry about ferrets doing are….

Shivering or trembling when waking up … that’s something they all do as they adjust their metabolic rate. Of course if you find your ferret shivering in other situations, it’s “hi ho, hi ho, off to the vet we go“!

Stretch, yawn ‘n’ slide … this is so cute. A ferret might decide it’s time for a stretch, so it’ll reach up to its full length, say, against your bed, yawn, then slide down, ending up flopped on the floor. Don’t worry – it didn’t suddenly collapse or faint – it’s just something ferrets do!

Sleeping like the dead … you can even hang some ferrets upside down when they’re asleep and they won’t wake up. Not every ferret has the dead sleep habit – some are fairly light sleepers and probably wouldn’t appreciate finding themselves hanging head down!

Having said that, I must put a caveat on that statement. Sleeping like the dead is fine if you know your ferret is healthy.

HOWEVER … if you suspect your ferret has insulinoma and you find your ferret sleeping like the dead, then that is not good.

If that happens, get some karo syrup or honey and rub it on your ferret’s gums because if you don’t, your ferret could just slip away in its sleep.

Scratching … some ferrets tend to scratch themselves quite often and it doesn’t mean they have a dreaded disease. Muis comes crashing out of the chest of drawers a couple of times a night and has a good old scratch, bell tinkling, then she gets back in. No disruption except to our sleep.





For those who live in countries where rabies is an issue, make sure your ferret has the vaccination at the necessary time. The first one should be given at 3 months and then your ferret needs a yearly booster.

In certain states in America, if a ferret just scratches someone with their tooth accidentally and the authorities confiscate the pet, they will euthanize it – regardless of the fact that the ferret has had all its rabies shots. Remember Kodo?

Canine Distemper

It’s important for all owners worldwide to make sure that their ferrets get their yearly canine distemper shots as this is a very unpleasant disease and is fatal.

In the US, they give kits shots at 6-8, 10-12 & 14-16 weeks and then at a year old. After that, they should have a booster annually.

Here in Perth (and I don’t speak for the rest of Australia), kits get 2 inoculations, a month apart, and then they must have their booster shots annually.

Check out the page on Canine Distemper for more information.

Some ferrets can get an allergic reaction so it might be wise not to rush away from the vet once your ferret has had an inoculation, just in case.

One thing I will mention was how Mash reacted with her first canine distemper shot. We took her to our vet and when he injected her, she gave the most angry, loud, penetrating scream I have ever heard in my life! It was so bad it hurt our ears.

No other ferret I’ve had ever made such a scream and after that one time, Mash didn’t do it again.

Quite extraordinary! I don’t know if the vet hurt her accidentially or she was so indignant about having a needle shoved into her. Poor little baby.



Spay / Neuter

Boys get really smelly when they’re about 6 months (sometimes even as young as 4 months) and start acting like absolute yobbos (Aussiespeak for unsociable hooligans), as described in the Breeding section..

Unless you want a stud for breeding purposes, you should get your boy sterilized once the smell starts getting pretty pungent and after about a week, once all the hormones have settled down, he will go from a brute with attitude to a sweet and gentle metrosexual fellah

The girls also smell slightly stronger if they’re not spayed but they certainly don’t have the disgusting habits that unsterilized boys do. However they do have the threat of aplastic anemia hanging over their heads in that state, so why risk anything?!

Of course some people like to take their jills to vasectomized hobs to bring them out of season but since the girls get dragged around the arena and come back smelling really bad after being with the boy, which in turn causes the girl to get beaten up by the other ferrets in your house, it hardly seems fair.

A quick visit to the vet and hallelujah, everyone is happy!



Ear Mites

Check your ferret’s ears if you see it scratching them excessively as it could mean ear mites.

Get a cotton bud (Q-tip) and gently clean inside the ear cavity. If the tip is covered with a black or orange goop and smelly, then treat the ferret with a suitable product recommended by your vet.

If you use Revolution regularly on your ferrets, it’d prevent ear mites from happening.



Fleas / Ticks

If you see movement on your ferret’s coat, or find little black flecks in the fur, then you can bet you have a flea problem. Don’t leave it as it will only get worse and could cause your ferret to develop anemia, in the worse case scenario.

Fleas will also happily take over your house, which really isn’t much fun!

When Revolution first came out, our vet recommended that we treated all our animals with it and told us it was safe to use 10 drops of the large dog solution for each of our ferrets.

WAFFS now have specially prepared tubes of a single dose of Revolution to use on each ferret. The dosage for girls is 0.2 ml, while the boys get 0.25 ml.

I have since heard other vets recommend using a tube of the 5-15lb cat dose of Revolution per ferret per month. Apparently Pfizer did a small trial with the 0-5lb kitten size tube and found it was not 100% effective in preventing heartworm in ferrets, whereas the 5-15lb cat size tube was.

Check with your vet to find out the best product to use to use on your ferret.

Flea collars are NOT to be used on ferrets. They (or their mates) could easily lick the substance off and poison themselves

If you find the fleas have infested your house, buy the necessary amount of flea bombs, get your pets out, follow the instructions on the can and make sure you kill the problem. Make sure you vacuum the floor/carpets extremely well afterwards so that no residue is left which could harm your pets.

There is a homeopathic recipe for the treatment of fleas which you can make yourself by mixing 1 oz of lavender oil diluted into 4 oz of water. Put it into a spray bottle for easy use.

Another recipe is mixing one bottle of Halo’s Cloud Nine herbal dip with 1 gallon of water. The dip contains many natural oils which repel and kill fleas.

I confess that haven’t tried either of those out myself.

Ticks, which look like black moles on the skin, have to be removed carefully so that you don’t leave any part of the tick still attached to your ferret. Frontline’s Top Spot is good for getting rid of fleas and ticks.

Remember that ticks can cause Lyme disease, so make sure you check your ferret carefully if you live anywhere where ticks could be a problem.

There’s a detailed article about flea control for ferrets written by Dr Susan Brown on the VIN website.



Various ‘Worms’ to Worry About



You would probably notice if your ferret had worms when checking through the litter tray. If you have your ferret dosed with Revolution regularly, you shouldn’t have any problems with worms.

Check the Internal Parasites page for detailed information on what kind of worms ferrets can get.



Ringworm is caused by a fungus and can be transmitted by direct contact with an infected animal or contact with a brush, bedding, etc. Humans can also get ringworm from an infected animal so it’s not a parasite you’d want to ignore!

If you find your ferret has a bald, round lesion which is scaly in the center and the skin appears thick, red and crusty, you had better take your ferret to the vet to have it treated.



Unfortunately ferrets can get heartworm and it’d only take one wretched worm in their hearts to kill them.

If you are already using a monthly dose of Revolution, then that should take care of any heartworm worries. If not and you live in an area with a lot of mosquitoes, then check with your vet for a suitable heartworm product.

There’s more information about heartworm here.




Ferrets DO NOT have sweat glands and really suffer in high temperatures.

If you have your ferret housed outside in a cage, please make sure there’s enough ventilation and shade to protect the ferret.

During the hottest days, make sure you spray your ferret and also leave a wrapped up bottle of water which has been frozen to help cool the cage down.

Also never leave a ferret, or any other animal for that matter, in a locked car with the windows up during hot days.

You can read more about heatstroke in ferrets here.



Declawing / Defanging

My personal opinion is that both are barbaric practices and should not be contemplated by a ferret owner unless a veterinarian declares it necessary, although why a vet would I don’t know.

Declawing involves the surgical removal of the claw and the bone it is attached to. Amongst other things, the procedure would mean that your ferret couldn’t grasp anything and certainly couldn’t climb up anywhere.

Defanging is just plain awful. I saw a defanged ferret once – some drongo (Aussiespeak for an absolute dimwit) had broken its canines with pliers because it had bitten him!




When a ferret gets scared or angry, it lets off what I term a “stink bomb” or “poof” like most members of the mustelid family do.

Unlike a skunk, the smell doesn’t take long to dissipate but like with all things, different people have different smell thresholds.

Descenting is the removal of the anal sacs and therefore eliminates the “stink bomb” from going off.

The vets I have dealt with in Western Australia think descenting is unnecessary and wouldn’t do it unless it was necessary for health reasons.


Shedding and Hair Loss

Spring and fall are the seasons when ferrets tend to lose hair, shedding their winter coats for summer ones, and vice versa.

If you have an older ferret, their coats can often look all moth-eaten and thin, and their tails can lose hair from the tip up so that it resembles a rat’s tail.

Hair loss on a ferret can be a worry and if it comes at a different time to the change in seasons, and you have a young ferret, then it would be a good idea to take it to the vet to make sure there’s nothing sinister happening.

If during the molt you notice blackheads on your ferret’s tail, or that it’s looking pretty grotty, just get some gentle ferret shampoo and give your little friend a bath. That should clear up the problem … but don’t wash your ferret often, as that will cause the skin to dry out and go itchy.



General Health Tips

Bumps and Lumps

Scruff your ferret and gently run your hand down the length of its body. If you feel any suspicious lumps or bumps, take it to the vet for a check up.


Yes, ferrets can get warts and they are easily treated by the vet. However if you find a wart-like lump, please take your ferret to the vet to check out as it might be a mast cell tumor. They are usually benign and can be removed easily.

And, never, ever treat the wart with wart ointment for humans. The son of friends of ours did just that and his ferret died a painful death after licking the ointment off.

Coat and Skin

Check the condition of your ferret’s coat and skin. Coats should be glossy and shiny, while skin should be pink and healthy looking.

Teeth and Gums

Check your ferret’s teeth just to see that they’re okay. A yellow tooth could mean it’s broken and that might cause problems. Brown scum at the top of the tooth by the gums is tartar build-up and might warrant a trip to the vet for a scale job.

Make sure the gums are pink and healthy-looking. White gums are a sign of anemia.

If your ferret has bad breath, it might be something more than gum or tooth problems, so it deserves a visit to the vet.

You could give your ferret the tips of fresh chicken wings to munch on as a flossing alternative. However I found that my lot wouldn’t eat them, they just stashed them away in my chest of drawers! As I got pretty sick of finding wings in my underwear, I stopped giving them out.

Check the section on Dental Problems for more information.


Your ferret’s eyes should be bright and clear. Cloudy eyes mean cataracts, which is not a big deal in itself, as ferrets can scoot around the house quite happily if they’re blind.

There’s more about cataracts on the Cataracts & Blindness in Ferrets page.


I wonder if any other pet owners are as anally fixated like us ferret ones! We all seem to get neurotic about the shape and color of poop, seriously!

If your ferret’s poop looks like brown toothpaste which has just been squeezed out, then everything is cool.

If it’s any other color or texture, take your ferret to the vet.

Click here for more information about ferret poop.



Poisons / Toxins

I don’t know why they say curiosity killed the cat because that expression should apply to ferrets first and foremost!

They are incredibly curious and that in itself could cause them harm.

Treat your ferret like you would a wilful toddler and make sure all dangerous things are kept out of their reach.

For instance, there have been cases of ferrets dying after they’d got hold of a blister pack of aspirins, scratched the foil and licked the pills. The owners were unaware of what happened so didn’t rush the ferret to the vet for immediate treatment.

I have to have 2 Panadeine Forte four times a day and need to have them on my bedside table at night. To make sure the ferrets can’t get to them, I have them in a tight-closing, very secure case for glasses. However when our little granddaughter visits, I move everything up out of reach so that there aren’t any accidents.

There are also a number of plants and household goods which are dangerous to pets so please make sure your pet can’t get to them.

Having said that, I wonder how many ferret owners still keep house plants in their houses – hmmm!

  1. My ferret has some thing in his face but i have no idea what it except flys or magots can u help thanks

  2. Tristan, I think this is something for a (ferret) vet to check out. I can’t help you, I’m afraid, as if it’s something which needs to be removed, only a vet can do that.
    Whatever you do, do NOT use any medication for humans on your ferret as if he licks it, it could kill him.
    If you need a ferret vet, please check out my Vets pages to see if there’s one near to where you live. I’m slowly going through all those pages to update them but hopefully the information won’t be too outdated!
    Good luck and big hugs to your boy from his new friends down under :)

  3. My ferret has been chewing /itching on his back these are my first ferrets and I’m not sure what it’s from he has some hair Loss in between his shoulders ?????

  4. Tiffany, I’m not sure what is causing the hair loss on your ferret so would suggest you take him to a (ferret) vet to be checked out.
    It could be that it’s caused by flea bites, or maybe his skin is too dry (have you been washing him often?), or it might be a sign of adrenal gland disease :(
    Only a vet will be able to tell you definitely what’s wrong. I hope it’s nothing serious!
    Hugs to you guy from his new friends down under :)

  5. Well the people before me had them on junk food so they refuse ferret food but they will eat cat food do you might think it’s their diet ?

    I know cat foods not good for them but I don’t want them to starve :/

  6. Hi we are having an issue with fleas on our ferret, he was treated with advantage as recommended by the vet 2 weeks ago and is covered in them again…. is there a better product to be using?

  7. Hi Brenda
    When I had a flea problem I found Revolution to be the best product. Got rid of fleas on my ferrets, dog, & cats and I didn’t have any trouble afterwards.
    Just scroll up here to “Fleas / Ticks” and you can see what kind of Revolution you should get for your ferret :)
    If you think the fleas have got into the carpet/furnishings, please think about getting a pack of “flea bombs” and place them in the rooms of your place. Once it’s safe to go inside again, you can vacuum the floor and then get your ferret back inside.
    If you have other animals, make sure you put Revolution on them too before “bombing” your house.
    I’m pretty sure that will clear up the fleas in no time :)

  8. Well I got home from work and let my ferret out to play on my bed. I noticed his eyes seemed glued shut even when moving a bit. So I applied very slight pressure by the eye and what looked to be mucus came out in a decent load. I’m not sure what to think or if I should be worried.

  9. Oh William, please take your little guy to a vet as soon as possible!

    I think he might have an eye infection and if he gets put on antibiotics, it’ll clear up and both you and he can breathe a sigh of relief and not worry yourself sick 😐

    I do know that sticky eyes is also a sign of canine distemper but, God willing, that isn’t the problem :( However take a look at the symptoms and if you think your little guy has this disease, you MUST take him to the vet ASAP!


  10. Um my ferrets right eye doesn’t want to stay open. And i don’t know what it is or what to do. It just started today HELP!

  11. Antashia, is your ferret’s eye still shut? If so, please take it to a vet to get checked out.
    It could be that the eyeball got scratched somehow and *might* get better by itself but if the scratch becomes infected, your ferret will need antibiotics and if you leave it, it could make things worse :(
    If you need a ferret vet, please check my pages re vets. Hopefully you’ll find one near to you!
