This, too, may be individual.If she was my cat, A couple of things I would keep in mind, is avoid anesthesia, never give any Metacam or other anti inflammatory medication, make sure she stays hydrated.
My cat had CKD, and since the diagnosis she went under anesthesia at least 50 times without receiving any damage from them. She was given Metacam lots of time, but of course she was always well hydrated.
