BATON ROUGE, La. — Call it a big CAT scan. Louisiana State University’s live tiger mascot was sedated this past weekend and brought to a human cancer center near campus, where he’ll be treated for a rare cancer. At the hospital, Mike VI received a CT scan and a radiation simulation. During the simulation, doctors set up devices that will keep the 420-pound tiger in position for precisely targeted radiotherapy to treat a tumor on his face. The LSU veterinary school says in a statement that doctors haven’t yet decided whether to treat Mike on one day or over two or three days.
