They require my photo ID and fingerprints just to by my crushed beer cans in Indiana. One would think trafficking in cats would be a tad more difficult. Who knows? Maybe the auto manufacturers are the end market. Won’t be long till microchips are all the rage for thieves.
At a minimum, a DL for steel at the yards here.
Other metals, an additional permit from the Sheriff’s department (free) in addition. Good for a year.
