I work at Petco, and while our store is clean I have seen MANY that are not. I cannot tell you how bad the animals in one Whittier Petco are kept. I have seen rats with intestines hanging out and have recieved no treatment. They are constantly fighting and wounding eachother and many are just left to die in the cage. The ferrets are just filthy etc. But the thing to remember is there are good petshops and bad petshops and each store is different. Our animals are very well taken care of, and I know for a fact they recieve vet care as before I worked at Petco I worked at Santa Clara Animal Clinic, and they would always bring their sick animals to us. They also adopt our their "non-adoptables" to various rescue groups instead of disposing of them or euthanizing them. I always hated Petco until I came here to Oregon and actually saw one that took care of their animals.
