The Lion's Busy (1950)

It's "Leo" the Lion's tenth birthday and his is given a book by his pal "Beaky" Buzzard which tells him that the average life expectancy for a lion is, well... ten years! What now ensues are a series of near death escapes for the lion each culminating with him ending up about to be a meal. After a while, "Leo" tries to turn the tables - without always thinking it through. Eventually the pair end up on the moon incapable of eating anything but marshmallows! A war of attrition - and I quite enjoyed it.
