1.
an EVIL PLACE where animals die everyday because the people hired have no idea whatsoever how to take care of animals. has had millions of lawsuits filed against them. petco should go curl up and die somewhere.. the problem is, where else is everyone going to get their pet stuff? (or pets?)
'did you see that thing in the paper about petco?'
'yea. i can't believe they found a bunch of starving guinea pigs and parakeets sitting in their own shit. i'm never going there again!'

My blood pressure is kind of low today. I know, I'll go buy a $15.00 rubber ball at PETCO.
