I am a new subscriber to the list, so I don't know if this has been discussed in detail before but I didn't find it discussed to my satisfaction on the ferret FAQ, so I figured I'd send in a post. I just lost a precious eight month old baby to juvenile onset lymphosarcoma, and I wanted to share my experience with that. Robin was acting completely normal until two days before his death. He had begun to calm down from the wild and crazy kit phase, but the vet said that was completely normal and I had a wonderful month or two of a very well mannered ferret. Last Wednesday I noticed that the boy was a bit lethargic; he wouldn't play with his best buddy, the wild and crazy four month old Moses, and just sort of cried when Moses came and chewed on him. A bit concerned, I called the vet who said that he might just be entering yet another phase of ferret-ness and calming down even more. I was advised to observe him; the vet didn't think this warranted a visit. Thursday morning Robin was still lethargic, but physically looked just fine. I called the vet and made an appt. for friday afternoon, and just resolved to keep an eye on him that evening. About 6 pm, I noticed (while rescuing him from another of Moses' playful advances) that he was severely dehydrated, though he'd been eating, drinking, urinating and pooping in normal amounts all along. Also, I noticed that the tissue of his gums and nose was rather pale. I called the vet and brought him in right away. A few x-rays later, I was informed that he had a severly inlarged spleen and lymph nodes, and that the probably diagnoses was Lymphosarcoma. The ferret could live on prednosone, but she could only promise me a few months with him. She attempted to draw blood, but he was too stressed, dehydrated, and his spleen was too enlarged to be able to get any out of him. I planned to leave him there for observation overnight, but he was unable to survive the stress and died shortly thereafter. I never had any indication, besides his lethargy of only a day and a half, that he was ill at all. I was informed that juvenile lymphosarcoma, though rare, strikes quickly. I hope that this may be of use to someone who has either recently lost a fuzzie to lymphoma and wonders if the experience was the same for someone else, or someone who may experience it in the future...
