So Ramsey went to the vet yesterday and it was not good...

Poor Ramsey came to me as a sick baby at 2.5 months old. I nursed him back to health, but down the road he began to develop a lot of health issues. He had a very sensitive stomach, helicobacter at 2 years and now he went in for another checkup for not eating much and losing a significant amount of weight within 2-3 days. Due to Ramsey's history, my vet is assuming Ramsey has Aleutian disease (AD) although apparently, there is no cure or specific procedure to guarantee this. We also did a blood panel and currently awaiting results (I'll know in a week or less) and I hope it is good news that he will be alright.

Out of curiosity and to prepare myself for the worse, has anyone experienced this disease with their ferrets before? If so, what kind of procedures did you have to perform? Cost expectations?
