It is always a possibility when you do rescue that you have sick ones come in. Some rescues do test all of the new ferrets; however, most that I know of do random ADV testing. The reality is that if you run a rescue, you won't typically have room to quarantine new ones effectively. If they have ADV I don't believe bleaching "everything" will work...because it's such a invasive disease...but I could be wrong. It doesn't hurt, and helps, but I think once you are ADV positive as a shelter, you basically can only take in ADV ferrets from that point on, as it lives for years in the surroundings. This is what I've read online, but I have no personal experience with ADV testing except that I've randomly tested ones during my years as a rescue. None ever were positive. Are you doing the snap tests or did they send the samples to the lab in another state? Could it be a terrible case of coccidian? Did the vet even bring up coccidia as a possibility? ADV effects animals differently and I think it might be odd to have three pass away of it so close to each other...but I guess it is possible. How long did you have them with you before they started going downhill? Were they cagemates before they came to you? How old were they? I am so sorry to hear about three ferrets dying in such a way. I am really sorry. I hope none of the others are displaying symptoms! By the way - What vet do you use? I also wanted to let you know that after you go to Williamston's vet, Cedar Creek Veterinary Hospital - at least once, then you can get the vet to meet you there after hours for emergencies. It comes out to about $100 to be seen at night, but sometimes you need to put someone to sleep quickly or maybe someone's arm is broken, who knows...but one time I had a kit who hit his head extra hard on the tile and we wanted to have him seen, and we paged the doctor, he came, and saw him. He was fine, and a little tired, but they do that service. In the Lansing area it is difficult to find any ferret vets who do not cost an arm and a leg after hours. Laryssa [Posted in FML 6103]
