Watch the amazing moment the tiger gives birth

The birth of a baby Sumatran tiger has been caught on CCTV.

Kirana the 7-year-old had two cubs at Chester Zoo, with security cameras capturing the arrival of one of them.

There's thought to be only about 300 to 400 Sumatran tigers left in the wild - so it's a pretty big deal to catch them giving birth.

The rare big cats are only found in a small area of Indonesia, and are the smallest breed of tiger in the world.
