Toxicity to pets

Mouse and rat poisons containing bromethalin cause swelling of the brain which results in neurological symptoms when ingested in toxic amounts. Unlike the long-acting anticoagulant (LAAC) mouse and rat poisons, this type of bait does not cause bleeding and is not treated with vitamin K1. Common signs of bromethalin poisoning include lethargy, weakness, incoordination (ataxia), tremors, seizures, paralysis, and eventually death. Unfortunately, this type of mouse and rat poison does not have an antidote and cause serious and long-lasting effects. Treatment includes decontamination, IV fluids, and specific drugs to decrease brain swelling. Cats are more sensitive to bromethalin than dogs. As this type of mouse and rat poison has a narrow margin of safety and no antidote, prompt therapy is often needed in all species.
