Get some tape, if it’s bright color, even better.
Make a small square on the floor out of that tape.
Sit back and watch your cat sit on the square
I introduced my wife to this concept by walking into the lounge, putting a square on the ground and saying “now we wait”, before walking out.
She looked at me confused and concerned saying “wait for what?!”
Not long after, I had caught a cat with the square!
