Cruel teenage girls laugh as they film themselves throwing hamster against wall 'to kill it'

Two teenage girls filmed themselves apparently killing a hamster - while laughing - then shared it online with their friends.



The disturbing clip shows the poor hamster being launched from a small blue box against an outside wall, followed by pictures of it still with the caption "she's killed it".



It looks as if the cruel killers filmed the video themselves, which has since circulated on Snapchat and Facebook.



It is understood the girls, one of whom is seen giggling during the incident, are from the Plymouth area, the Plymouth Herald reports .
