Start two weeks out
Leave the carrier open in a room your cat already uses. No handling, no treats inside yet - just let it stop being an event.
Then make it worth entering
Feed near it, then just inside it, then at the back of it. Each step takes a few days, and going backwards is normal.
Practise the lift
Pick the carrier up with your cat inside, walk a lap of the house, put it down and open the door. The lift is the part most cats object to, not the box.
