Mama cat eating her baby

this weird cat just came out of nowhere and started staying in our back yard and gave birth to four little baby kittens and the first one died. so, my dad threw it away and then the other 3 kittens were killed and eaten by the mother cat! it’s so creepy and scary. is it natural to eat your own babies??? i dont know. but yeah i only got the chance to record the last one that she ate. twitter: blog:
