Catstipation: Legislators Take Action To Stop Gruesome Cat Experiments At VA Our friends at the White Coat Waste project (WCW) are at it again hitting back against VA waste of taxpayer dollars on animal experiments. But instead of using op-ed’s and other pressure points in DC, WCW is using billboards to drive home taxpayer accountability. Over the years, WCW has helped bring attention to the use of taxpayer dollars to experiment on animals when appropriate substitutes can be found.
