Petsmart I do NOT recommend

I was at Petsmart yesterday to get some guinea pig bedding. I go and look at the guinea pigs just to see their cute faces. What I saw was downright disgusting. First, I notice the flies around the tank. Then, I look down at the floor of the tank. The bedding looked caked right into the tank floor. I am going to go e-mail the Humane Society right now. I think if I complain they'll change it. I'm also putting bad reviews about the particular store. It's the store in Dickson City, PA.
