Do kangaroos eat joeys

Answer 1

No, they do not. Female kangaroos will do nothing to harm their joey.

There have been instances of kangaroos throwing their pouch open when they are being chased, but this is not the case unless the joey has reached the age where it should be independent. Young joeys are not exposed to danger in this way. Older joeys have, on occasion, been known to fall from the mother's pouch when she is being pursued, but younger joeys would not survive outside of the pouch.
