As my my signature (and tattoo) say, CARPE DIEM!

I wish I had the ability to rescue a few that I have seen at pet stores recently, but space, time, and money are ALL issues. My girlfriend and I have been discussing what can be done about neglectful pet stores recently, and haven't really come up with much. I know that buying neglected pets from them only rewards their poor care, and offering "helpful tips" often goes ignored. Any tips?
