My method for quietly ‘handling’ such things would be to open a window about four inches and from the other side of the room carefully implant a copper jacketeted brain plug into the cat.
These 90 grain, copper jacketeted brain plugs are the neatest little thingys. All dietary needs for the cat would immediately cease. They lay down right where they are at and offer no resistance whatsoever to transportation from the area.
“Dear, you’re acting strangely?”
