They think they might have a name for what's ailing Mr. E - besides looking worse, if possible, from today's visit to the vet.
It's Cushing's Disease (or Syndrome). Apparently quite rare in cats, it is the effect of malfunctioning pituitary or adrenal glands. They tell us it is treatable, although a preliminary online search tells us that the prognosis is not so great - provided the animal survives surgery to remove any tumors. Treatment is going to be tricky. And expensive.
The vet took a skin biopsy, pulled a bunch of loose teeth, shaved off a lot of Mr. E's remaining hair, and sent Mr. E home with even more medication.
We are going to do our best for you, Mr. E.
