I don't hate Petco like many people do. The one near me is actually better in care of their animals than most smaller stores in the area. They seperate their rats/other rodents by sex and size, and use good bedding (aspen, no pine.) And their snakes, while they are all in one cage, have hidespots and a UTH on a dimmer, and they all eat according to my husband's cousin, who works their reptile department. He had made some changes for the better, as well as in the fish department.. but the tough thing about saying "I hate petco" or "I like petco" is tricky. Some locations are so nasty that I would not step foot in them, according to what I have read here. Then there's the one in West Seneca that is really not bad at all. And they are into adopting-out cats/dogs as opposed to selling them; something that alot of local shops should learn as well.. argh!
If you don't have your PALS card with you, but have one, they can look you up in their computer at the register.
