The group, R.A.T.S., solves a rat problem while preserving working terrier breeds. We’ve talked about this here before as being a “green” approach to a vermin problem, and we mentioned at the time that while we actually like rats, they are problematic. The rats are dispatched quickly with a broken neck, far more humane than using poison that works as an anticoagulant causing the rat to bleed out over days.  For more information about R.A.T.S.: https://www.youtube.com/watch?v=E16qHD55uWk
