I'm so very sorry for the loss of Heineken. If you can't afford the surgery perhaps you could medicate Resen in the meantime, this could buy him some time. Has he had an ultrasound yet to determine which adrenal gland is affected? Left adrenal surgery is pretty easy, right adrenal surgery is extremely risky and only some vets will do the surgery. The right adrenal gland is attached to the vena cava (main vein) and depending on how it's attached to that vein and if it also interferes with the liver determines if it is operable or not.
