Specific clinical signs can include widespread bruising, bleeding into body cavities, and blood in the urine or feces if the bleeding is sudden and significant, then cardiovascular shock and death can result.

Ingestion of a significant amount of anticoagulant rodenticides results in interference with blood coagulation and spontaneous bleeding. The time between exposure and development of clinical signs is dependent upon the specific chemical and amount consumed. Rodenticides are toxic to many species of birds and mammals including pets, farm animals, and wildlife species.

Non-anticoagulant rodenticides vary in their mechanism of action and include bromethalin, strychnine, cholecalciferol, and zinc phosphide. Anticoagulant rodenticides work by interfering with the activation of Vitamin K, a critical component in the production of blood clotting factors in the liver. Rodenticide toxicity can be caused by any of several types of rodent poisons that fall into two general categories, anticoagulants, and non-anticoagulants.
