(Subbed) Sloth

One of the famous superstitions in Japan is 獅子の子落とし - "Dropping your children into the ravine" - referring to the lion shoving their cubs into the ravine and will only raise the ones that make their way up. It suggests to any parents that if you want your child to grow up strong and competent, sometimes you have to let your children make mistakes or show them hardships.

At any case, here's a news about the lion mom actually rescuing the cub.
