The video has gone viral. A baby alpaca was attacked by a cougar in the dead of night and a brave mama alpaca fought off the cougar - the video is remarkable but the baby alpaca now needs medical help and a group of Samaritans in Washington State have stepped in to raise money for the medical costs.

This video will bring you to tears.

"Lucky" was only a week old but Mama fought off the cougar and saved her baby.

"Lucky" is lucky to be alive but the medical costs are pretty steep so folks are coming together and donating to Lucky's recovery.

You can follow the link to the Go Fund Me page here and it's already raised over $1500 on the way to a goal of $5000.
