Moving house.....getting cat in pet carrier. DEFINITELY
All the removal men etc freaked her out during the day......got her corralled in the sitting room with pet carrier.
Got hold of her, tried to ram 'persuade' her into carrier. Marvelled at the four extra legs she suddenly produced that welded clamped themselves to the outer rim of the carrier, just as you'd unhook one, she'd get another braced to prevent entering the carrier.
After 5 minutes of bloody painful cat wrestling, a perfect 45 degree v shaped laceration on my hand had appeared (still have the scar!), dripping with blood, we tried one last time.
At this point the cat turned into Bruce Lee, complete with air ballet flying, threw itself across the room in a perfect, graceful arc, landed on the floor, hooked up a loose floorboard with 1 claw, lifted it, disappeared under floor and the board popped down exactly in original position like a magic trick!
Once under the floorboards, she was gone...not a hope of retrieval.
This was 20 minutes before completion and the new family were pulling up with removal vans outside.
So it was. "Hi, welcome to your new home, hope you're happy here, btw there is an insanely angry cat somewhere under the floorboards."
She apparently appeared after 3 days, hungry and deflated, we had to travel over 100 miles to go pick her up from the bemused new home owners. We didn't even try to box her, just shoved her in the back of the car; where she sulked the whole journey.
Never again.....
