So the California Hamster Association  is accusing Justin Bieber of Animal Cruelty after he gave away his hamster to a screaming fan.They said that hamsters are fragile creatures that "often succumb quickly to illness and death," especially when faced with "sudden environmental change."

In short ... "The moment that hamster was handed off to a screaming girl in a harsh, frenzied environment was likely the moment it gazed at the short path to its doom." The CHA says if Justin no longer wanted the pet, he could have left it in the care of an animal shelter or rescue center ... so they could've handed it off to a responsible new owner in a safer manner. 

Some people have too much time on their hands LOL
