Melissa, You asked several important questions in your post. I'll do my best to answer. What types of reactions can you expect from vaccinations? Usually none. In rare cases, the ferret will be allergic to one of the ingredients in the vaccine. These usuall occur within 30 minutes or less, although I've heard of reactions occurring 45 minutes later, and strongly suspect some that do not appear for up to 2 days. Generally you'll see the ferret either turn very pale, lose control of its bowel, perhaps try to vomit; or the fur will 'poof' out (bottle brush), the skin turn bright red; often loss of of bowel control, and sometime difficulty in breathing. The vet needs to take immediate action with antihistimine, and steroids. Sometimes an incubator is needed to stabilize body temperature, and IV. to rehydrate. It's very scary to have happen, but is rare. Rabies? Yes, it is rare in ferrets, and all data to date indicates that the ferret will die before it can pass on the virus. The virus is normally injected by a bite of a rabid animal that has the virus in its saliva. The virus from the bite wound travels to the nerves and eventually to the brain where it reproduced very rapidly. In many carnivores, the virus also at this time enters the salivary glands and the saliva. The animal is driven mad from the pain and confusion of the virus in its brain. It may lash out at anything nearby, biting and passing on the virus for the cycle to repeat. Ferret can develop rabies, but if the virus never enters the saliva, it can not pass it on through a bite. Studies in France, Germany and recently in the US, have shown that the ferret does not "shed" the virus ( have it present in the saliva) before it dies. Dogs, on the other hand, can shed the virus for days (recent studies have found it to be years in rare cases) before they even show symptoms of rabies - hence the 10 day quarantine period in order to see if the dog does develop symptoms. Most studies on the dog show that if they dog does not show symptoms within that time, then they did not have the rabies virus in the saliva at the time of the bite. (They still could have rabies, just that they would not have been "contagious" at the time. Ferrets getting along? Usually takes several weeks for ferrets to begin to accept one another. Just make sure that there is no blood drawn. What you are seeing may be a dominance demonstration, overzellous play, or even normal ferret antics. It should settle down. If there is blood, separate for a while-perhaps cage the aggressor for 5-10 minutes where it can see the other out playing. Then try again. Flea spray with Ovitrol? If it say that it's kitten safe, it's probably safe for ferrets. We use Vet Kem with Ovitrol, and find it very safe and effective. Do start with a ring of the spray around the neck first to keep the fleas from migrating to the head, eyes, nose, and ears. Then do the body, legs, tail. Finally spray some on your hands and rub it in the ferret's head, muzzle, ears. WAsh the bedding in hot bleach water. Get a kitten safe area spray for the carpeting and furnature. Fleas spend most of their lives off of the animal. You have to get them where they are hiding. Dick B. [Posted in FML issue 1726]
