How to immobilize an injured or frightened cat
Wrap the cat in a pillowcase then put it in a box.
One of the safest and easiest ways to immobilize a cat is by wrapping its body in a pillowcase. Place your cat on top of a pillowcase lying on a flat surface, several inches from the edge of the pillowcase.
Cover the cat's body with the short side of the pillowcase, leaving its head out. Grab the other end of the pillowcase and pull it over the cat's body.
