No, I chop them up for her into bite-sized pieces so she won't drag raw chicken all over the floor. Chicken necks have soft, edible bones, and they are great sources of calcium for cats. They also help keep their teeth clean.
They should not be given to cats who have never eaten them before without supervision, and they should never be cooked since this causes the bones to splinter; eating cooked chicken bones can harm or kill them.
