"Officials Call for Limits on Use of Super-Toxic Rat Poison"

"D-CON kills rats and mice, the label reads. And, according to state and federal officials, it can kill hawks, owls, eagles, foxes, bobcats, mountain lions and other non-targeted wildlife too."

"So can competing brands. Pesticide manufacturers have been selling a new generation of more potent anticoagulants because mice and rats have built up some resistance to the old standby warfarin.

These super-toxic rat poisons have a longer half-life before they break down, meaning they are more effective at working their way up the food chain -- not only killing rodents but their natural predators.

The California Department of Fish and Game has confirmed 240 cases of non-targeted wildlife being exposed to the anticoagulants that work by causing animals to bleed to death."
