Dear Rob,

Hypercalcemia is generally not very common in ferrets. the
hypercalcemia of malignancy of course has to be considered, and
lymphoma certainly can do it. Abdominal masses are most commonly
adrenal in origin, and I don't think I have ever seen one of those
result in hypercalcemia.

I think that actually renal disease is probably a more common cause,
but of cause that would show up in other tests as well.

A normal lymphocyte count with about 30% of the differential sounds
pretty textbook to me. I'd be intersted in hearing what the biopsy
shows on this ferret, and if the calcium drops after removal....

With kindest regards,
