One cat really didn’t like being confined and would lash out (a neglected runaway I eventually got back to his owner - * the confinement was only gently herding him into a corner to dab on flea and worm treatment, nothing else was forced on him) but with patience he started to spoon with me over the covers on his own. He would allow me to pick him up.

If he’d crashed for longer than a few months I might have built enough trust for the cat tent
