I'd have to concur that the spider bite sounds a lot like a brown recluse spider bite. Did you by chance save the spider so that it can be I.D'ed? In any event, I would definitely take the ferret to a vet. My Mom had a brown recluse bite a few years ago, and was quite sick for months. The doctor told her the venom from the brown recluse can be as deadly as venom from a cobra. The bite can be lethal to people, and I would imagine even more lethal to small pets like ferrets. - Ela Ela Heyn Harborside Mail Stop 3024 201-860-3336 [log in to unmask] [Posted in FML issue 3140]
