Pac was Justin's hamster. Justin gave his hamster away to a fan on December 12, 2012 after his performance at the Atlanta Jingle Ball show. The hamster has passed away due to what is thought to have been a chronic renal failure or a low protein diet. Super-fan Tori McClure told TMZ the cute Russian dwarf hamster began losing its hair and a visit to the vet was unable to save him. She buried the beloved rodent in her garden, insisting, 'it's very peaceful there'.
Writing on her Twitter page, Tori revealed Pac has gone to 'little hamster heaven', adding: 'He was OUR baby & @justinbieber I still can't thank u enough.' The teen idol's followers sent Twitter into a meltdown when they heard the news, and got #RIPac trending worldwide
