Mice go into hiding immediately
after sensing some predators around,
but they certainly play
when feeling away from harm or danger.
We've already seen some videos of cats and dogs
running and playing around
with no harm done,
and enjoying each other's company.
And even more unbelievable
is a man hugging and cuddling some adult lion or tiger
as if it was just an ordinary household dog.
Believe it or not,
these unusual things are happening.
These are stories about relationships between humans, animals or between humans and animals.
