Please don't use poison to kill mice. If your ferret eats a mouse that has been poisoned, particulary with the anticoagulant, the ferret will be poisoned as well. Mice may carry the poison into their hiding places and if a piece is dropped along the way and your ferret eats it, your ferret will be poisoned. Some pest poisons may not kill a dog or cat, but they may kill a ferret. Quite a bit of weight difference.
