A. Rat Poison
Rat poison, or rodenticides, are usually non-specific pest-control chemicals made for killing rodents. There are two types of rat poison: the anticoagulant and the non-anticoagulant. Anitcoagulant rat poisons causes internal bleeding in rodents and usually takes two to six days for the rodent to die while non-anticoagulant rat poison takes only hours for the rodent to succumb to death. These two types were hazardous for both animals and humans when consumed.
