Your ferret(s) need a lot of attention, love and respect. Treat an animal well and you will get a good many years of love and respect back from it. Two or more ferrets is recommended since they're more fun to watch! And also keep each other company.
Ferrets should go to a vet at least once a year for a check-up, rabies and canine distemper shots. Ferrets can die from canine distemper. And *IF* your ferret comes into contact with some disgusting rodent or other animal that may be infected with the rabies virus it is a good idea to have already had it's shots!
In general ferrets are not a carrier of rabies. It is VERY uncommon for a ferret to contract rabies unless bitten by an animal already infected. However please do have the shots given to your ferret before this can happen. Ferrets will in fact die from rabies. Some states will confiscate a ferret that has bitten or nipped someone and DESTROY it for rabies testing. You have a far better chance of saving your ferret if you have a proof of shot records handy.
Ferrets can NOT live outside alone and if you let them out like you would with a cat or dog chances are it's not going to come back and will die if not fed for three to four days. They can not *fend for themselves* and therefore die. Since ferrets have been domesticated for so long they've lost all natural instinct to survive in the wild.
If you have a home with children it is advised to keep ferrets caged when you can't watch them. Never leave an animal alone with a small child as it can be traumatic to the animal and/or the child!!! I would never have a cat roaming around my house with infants or small children, cats bite more often than a full grown ferret normally would. Full grown ferrets usually do not bite.
If there's anything that I left out and should be brought to attention please Mail me!
Ferrets can get sick and when they do they have a tendancy to loose weight, a good way to fatten up a sick ferret is a substance called Duck Soup
