This 10 year old MN DSH cat has an elevated Calcium (12.2, ionized calcium pending) and weight loss (16 down to 14), remainder of bloodwork normal.

Kindey right

Both kidneys looked similar. To me the kidneys look very abnormal; the remainder of the abdominal organs looked normal to me; ?I performed FNA of each kidney and the spleen.

I am thinking this is lymphosarcoma and of course cat belongs to a staff member…
