A guy named Anthony Klein adores his ginger cat Sammy.

He cares for his cat as if it were his own child, and even sings lullabies to it.

Some time ago, Anthony found out that his cat likes not only to listen to songs, but also to sing along.

He filmed a touching video in which he performed the famous children's song "Twinkle, Twinkle, Little Star," pausing especially for Sammy, who, despite his nap, sang along with his owner all the time.

Anthony's video quickly went viral. And this is not surprising.

Such an incredible cuteness can win even the hardest hearts.
