Cats can have cooked turkey giblets and other parts of the cooked turkey.
Some cats eat raw meat but it's best to cook the food first to kill the bacteria on the meat and prevent the cat from getting sick.
I feed my cat cooked turkey giblets whenever I have turkey and even give my cat some actual turkey when I have it especially on Thanksgiving since he's a part of the family too and deserves something other than cat food all the time.
