ok found it...well some of it. Black rats (Rattus rattus) and Norway rat (Rattus norvegicus), which helped make Sprague-Dawley, Wistar rat,Long-Evans rat, Zucker rat,Hairless rats strain, and the RCS rats. You Know Where would have to freez over before they out law any of those. All these rats are a HUGE role in how/what we use for medicine or lab testing, few ppl keep them as pets. As for a the common rat or ones we like to feed are snake are called the Fancy Rat which is consider a domesticated Rattus norvegicus. With that being said there is no worry if 669 some how gets passed there is no worrys of snakes going hungry.

This bill would fly out the window if they wanted to try to eradicate the common rat, it would cost us Billions of dolloars
