Mich: Yeah we have laws, though most of them aren't more then a slap on the wrist.
And it doesn't matter, these animals are just considered cargo.
A pet magazine I used to subscribe to when I was a pet sitter, would constantly have these adds for a big company, I can't remember the name of it now, I think it was Huntz or something.
At any rate it had a big picture of a 18 wheeler, a warehouse style building, and then a picture of I guess what was the company owner and a "happy" looking puppy. And it was a shipment add for all the pet stores out there to buy from them.
