A couple opinions and a free offer. Serious ear mite infestation can leave residue under the skin of the inside of the ears. It may be mite remains of some sort. It seems to do no harm once the mites are treated and gone. No need to use over the counter preparations or other oily mite treatments. They rarely work and take weeks to fail and meantime the animal suffers. GO TO YOUR VET and ask for IVERMECTIN either as a solution in the ears, or by injection. Often only one treatment is needed. Why mess around with hopeless attempts? This is state of the art treatment--quick, inexpensive and humane. Some talk about ferrets "screaming". This is certainly unnerving and if you're lucky, you never will hear it. It generally is a result of seizures--a tough situation with ferrets--due to the last stages of disease, dehydration or hyperinsulin coma due to insulinoma. The emergency treatment consists of valium injected directly into the vein. This usually relieves the seizure but does not cure the cause. If it is due to dehydration (a real possibility these days), rehydration by IV catheter may relieve the symptoms. If it is due to insulinoma, administration of IV fluids with 5% dextrose may temporarily relieve the coma. In other disease cases, there may be no long term solution. Only your vet or emergency facility will be of help in this case, but do not euthanize your ferret without determining the cause, once the seizures have been controlled. It may not be a fatal situation! Is your vet diving into adrenal surgery? We have a diagram which guides the surgeon's hand whether the tumor be right, left or both.
