Project Description
Bromethalin-containing rodenticides are toxic to all animals, especially cats. Toxicity mainly occurs due to cerebral edema. It’s important to note that anticoagulant rodenticides also have a risk of toxicity if ingested.
Signs and symptoms of toxicity: Clinical signs of toxicity in dogs include weakness, paralysis, tremors, seizures, and coma. Cats are more prone to show paralytic signs of toxicity.
Toxic consumption: In dogs, ingestion of 2.5 mg/kg (1.1 mg/lb) of bromethalin can be fatal. In cats, the toxic threshold is lower at 0.45 mg/kg (0.2 mg/lb).
