Our youngest, Maximus, is sick and miserable. He is very lethargic, only getting up to use the litter box and eat a little bit, then just lays there in front of the food bowl. He gets little brown crusties in the front corner of his eyes, ocassionally does this really soft sneezing, and his nose is bone dry. I've started syringe feeding and watering him. I took his temp about 15min ago and it read 104.6 OBVIOUSLY we are getting him into the vet ASAP, but is there a way to bring down his fever in the mean time? 104.6 seems pretty high :/ my first-aid kit say normal temps are between 101-103.

Just keep pushing the fluids into him until he gets to the vet's office.

Update: Got him into the vet this morning as soon as they opened. Ended up having to leave him there :( Vet suspects possible DIM (Disseminated Idiopathic Myositis) based on all the symptoms he's exhibiting . They took a blood test and I believe muscle biopsy and sent it in for testing, and should have the results tomorrow morning. Vet said she put him on antibiotics and steroids, and told me he has perked up a little since. I'm HOPING that it's just something as treatable as an infection, but I can't rule out the possibility of a terminal disease. I will update again as soon as I get word on the test results.

I hope it's a treatable infection.  Best wishes.  DIM isn't too common in ferrets.  Odds are in your favor.

THE DOOKS OF HAZARD

I hope so too. All his symptoms point to DIM though, which worries me. Lethargic and weak, loss of appetite, reluctance to move around, fluctuating fever, high white blood cell count, dehydrated, and he's under 18months old... I'm just so worried :( He's too young to be having such issues.

Update: Back from the vet with our little guy. Vet is fairly comfortable with her diagnosis of possible DIM, so we are beginning treatment of Chemotherapy once every 2 weeks, steroids (pred) twice a day and fluids under the skin every other day. He has a 50/50 chance right now. Could go one way or the other :( Really hoping he pulls through. He's too young to be going through so much.

Pardon my vernacular, but that sux.  No idea of the cause, is there?  
Best wishes.  I have only heard of it once before in ferrets, but I know it happens.  

THE DOOKS OF HAZARD

Nope, no one knows exactly what causes it yet :/ DIM is still not very well known about. Figures one of ours ends up having it Thankfully they don't believe it's contagious, and I only have to keep him separated from the others for about 72 hours after each treatment because of radiation exposure.

I'm wondering how your little guy with DIM is doing. My youngest was just diagnosed today and we're trying to decide what's best for him. The mortality rate is extremely high and I hear the medication that's supposed to help is pretty nasty stuff. I hate to see him suffer so much. I'd really appreciate any words of wisdom from someone who has been through this.
