I found this link from the Peta website. Very cruel!

"The majority of animals sold at PETCO come from breeding mills. At PETA, we have received complaints from horrified employees at some of the bird, reptile, and other small animal breeding mills that ship to PETCO. Many animals arrive before they are weaned and become so sick from transport that they die along the way or shortly after they arrive at PETCO."
