TopDo cubs kill and eat each other?
For the first few weeks of life, cubs fight to establish dominance, and the weaker cubs may be killed: around 20% of cubs die in the first four weeks of life, probably as a result of these fights. Older cubs are sometimes also killed. Any dead cub, however it dies, is likely to be eaten by its littermates; there is no point in wasting a valuable source of food!
