'Hero' cat rescues boy from dog

A new video captures the moment a cat attacks a dog that bit a child.

The video starts with the boy riding a bicycle.

A dog suddenly appears from behind and bites his leg. As the boy falls to the ground, a cat runs in to rescue the boy.

The cat attacks the dog, and the dog runs away quickly.

A woman, who seems to be the boy’s mother, appears in great haste and cares for the boy.

The cat comes back to check whether the boy is OK after chasing the dog.
