Cats like high places. Don't fight it, make him/her a bed up there.
That's what I was going to suggest as well. Maybe even make a small wooden shelf high up in a corner, and a board covered with hemp rope (or cross sections of corrugated cardboard) as a cat ladder.
I don't know if it works for cats too, but rubbing one of your own old sweaty-stanky t-shirts or towels on your dog, and putting it inside their new bed, gets the message across immediately and without error.
When I first met my brother's Norwegian forest cat, Elvis, who normally didn't like new people much, giving the slow blink and drawing a large circle in my lap with my finger was enough to get him to sit in my lap for a bit.
