When we reported on the fact that Justin Bieber gave away his pet hamster Pac to a fan who pledged to treat the adorbs little rodent like royalty, we did suggest that maybe, just maybe, The Biebs had acted a bit irresponsibly with the critter.

The folks at the California Hamster Association – which we never knew existed until now -- are hopping mad at The Biebs for his action and they are letting the whole world know that they think the singer did wrong by Pac.

A CHA rep spoke to TMZ, accusing The Biebs of "animal cruelty" for gifting his pet to a fan. Turns out that hamsters are not just cute; they are also fragile and can often get sick and die when thrust into "an environmental change."

Well, The Biebs pawning Pac off on a fan certainly qualifies as a major lifestyle change for the little guy. The CHA claims that the proper procedure would have been to relinquish the critter to a shelter or a rescue facility if he no longer wanted it.

The rep also said, "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."

Doom? Really? While we can understand that concern, TMZ posted photos of Pac in his new crib with his delighted new owner Tori. It looks like Pac is living pretty large, is adored and well-adjusted, since a gift from The Biebs is to be cherished.

While we don't disagree that The Biebs should have kept his commitment to Pac as opposed to giving the furball away as a cool gift to a fan, it seems like Pac is in safe, happy hands, and in a more stable environment than, say, on a tour bus.

Are you Team Biebs or Team CHA?
