Help me get health care for my ferret, Fred

My ferret, Fred, was recently diagnosed with adrenal disease. He is an absolute sweetheart who loves to ride on my shoulder and tickle my neck, cuddle with his siblings, and make nests out of stuffed animals. I care about him deeply and I want to get him the care he needs. The total I am asking for is to confirm the diagnosis, get him treatment, and treat an unrelated issue with mites. This won't cover the total cost of my vet visits, but it will greatly help.
