“Are cats the new dog?” TMZ asks. “Both Paris Hilton and Nicole Richie were recently seen buying cats in Hollywood within days of each other, which is sure to set a new kitty cat trend.” That’s stupid and really scary. What we want to know is What has Paris done with her dog(s)? And Why are the former friends buying cats when they could be getting them from a shelter? It’s official: We hate these stupid hateful girls.
