I figured that title would get your attention.
Here is why I ask... a friend told me that a US Supreme Court case determined that the US Constitution prohibits the Federal government from regulating "transportation across state lines" unless it has something to do commerce. This apparently was a case where a person had a small amount of marijuana that was for their own personal use, and since they had no intention of selling it, it wasn't commerce. My friend thought it was probably 3-5 years ago.
This might at the very least save our pets for those people who own an animal that becomes banned and later move to a different state. But hopefully it might help win some congressmen to our side. Some people who could care less about pets might get all fired up about an unconstitutional law.
