2. An obligate, or true carnivore, is an animal that subsists on a diet consisting almost exclusively of meat.

They may consume other products presented to them, especially animal products like cheese and bone marrow or sweet sugary substances like honey and syrup; but, as these items are not essential they do not consume them on a regular basis.
