This can be especially useful for very wriggly cats or if you don’t have a second person to help hold your cat.
Use a mid-sized soft towel – not too large or it will be unwieldy. Put the towel on the floor or a flat stable non-slip surface and then put your cat on top of the towel, facing away from you.
Bring up one side of the towel and then the other, around the cat’s neck so that your cat is thoroughly wrapped and cannot get its front legs out of the opening.
Hold your cat gently but firmly in the towel.
