On top of what’s already mentioned, Petsmart and Petco both get their animals from prt mills. Which is also why so many of their reptiles are sick/die easily. I don’t like PETA, but if there’s one thing I will grudgingly concede they are good at, it’s exposing pet mills. If you can stomach severe abuse and neglect, look up their footage of Reptiles By Mack, which is Petsmart’s largest supplier even after the exposition if I’m not mistaken.
