This is what I found on MIRROR.CO.UK:

A hero cat pounced on a baby crawling towards a steep flight of stairs and saved him from falling down.

Footage shot in a living room in Bogotá, Colombia, shows Siamese cat Gatubela leaping into action when one-year-old Samuel León heads towards the stairs.

The baby, wearing a red bodysuit, makes his way past a cot and a rocking chair, while the cat keeps an eye on him.
