Turkey Drums have a lot of meat on them making them a great meal for your pets. You can get the drums with or without hearts and liver as well as with or without fruits and veggies. Turkey Drums by themselves are 20% bone. When you add the hearts and liver to the meal, this meal is a nice 80-10-10. We grind the bones pretty finely as well so there will never be any bone shards in our blends.
