What are the most common reasons for full term kittens to be born dead?
It could be anything. It’s probably a birth defect. Thousands of things can go wrong with the little ones before they’re even born. The mama didn’t clean them well/quickly enough. Or she cleaned them too much and smothered them. Other guesses: An infection of some sort. Bacteria and parasites can kill babies. Trauma. Cats are tough, but if mama was hurt, that could be it.
