Wanting to get one

thxs for ur comment

I would say not to let the ferret and birds come into contact with each other. Perhaps you could make a ferret proof pen for your birds just in case the ferret gets out, and do some other little things like putting a bell on your ferret so you and the birds can hear him wherever he may be. Also, always supervise your ferret when he is out of his cage.

Though if you think it is too much a risk if the ferret got loose then you should not get a ferret, for the welfare of your birds.
