Unless they have a good caretaker that ISN'T her, they'd probably be better off having stayed at the pet store. This is the same woman that couldn't be bothered for a week to pick up a kitten after it was neutered, and there are reports from her staff and neighbors that she locks her little dogs in closets and forgets about them, and some have died, they roam the neighborhood and she doesn't care,and all sorts of horrible things. That and she's a BYB.
Granted, those reports might not be truthful (I don't trust the media to not exaggerate), but if you put in just a basic Google search for Paris Hilton and Animal Abuse you get plenty of hits.
It's cool that she's an animal lover and all, but I really wish she'd hire better "pet wranglers" to care for her pets. While I don't get why we care about Paris Hilton in the first place, she is in the public eye and should be a responsible pet owner. Pets aren't accessories and she hasn't learned that yet.
