No More Iguanas from PETsMART Being green isn't easy.
Green iguanas are the most disposable pet in America.
Pet Owners Survey, there are 2.25 million pet iguanas. No one knows exactly how many are given up, but some estimate about half of all the prehistoric looking reptiles are ultimately dumped by their people. As overrun as shelters are, imagine the horror if half of all the more than 130 million dogs are cats were tossed away like trash. In Minneapolis a wayward green iguana was recently rescued from a tree. The lizard was quite literally freezing to death.
