This week is National Pet Poison Prevention Week! Each day we will be highlighting a potential toxin that resulted in the most number of calls to pet poison control in 2024. As always, we recommend saving the ASPCA Poison Control contact information in your phone: 888-426-4435.
Featured today is: animal poisons
Check out these facts about two types of rodenticides- anticoagulant rodenticides and bromethalin rodenticides:
☠️ Anticoagulant rodenticides kill rodents by preventing blood clotting. It comes in forms such as bait blocks, soft baits, pellets, powder, grain, and liquid.
☠️ Pets may become poisoned either by eating the bait directly or, more rarely, through secondary poisoning by eating an animal killed by the poison.
☠️ These types of rodenticides cause excessive internal bleeding. It may take 3-7 days before symptoms appear and bleeding is not usually noticed directly although in some instances, the pet may bleed from the nose or mouth.
☠️ Symptoms of internal bleeding include: weakness, depression, increased respiratory rate or difficulty breathing, coughing (which may produce blood), pale gums, decreased appetite, distended abdomen, vomiting, bloody or tarry stool, swelling or pain in the joints, and bruising. If bleeding in the brain occurs, neurological symptoms may be present. Death is likely to occur without treatment.
☠️ Bromethalin rodenticide targets the central nervous system and causes brain swelling. It comes in the same types of forms at anticoagulant rodenticides. Secondary toxicity is unlikely to occur from eating affected rodents.
☠️ Neurological symptoms occur in 2-5 days. Onset and severity of symptoms depend on the amount of rodenticide ingested.
☠️ In sub-lethal amounts, delayed paralytic syndrome occurs in 1-5 days and progresses over 1-2 weeks. Symptoms include a subtle onset of mild lethargy and decreased appetite and progress to limb weakness, incoordination, and paralysis.
☠️ In doses greater than the lethal amount, acute convulsant syndrome occurs in 2-24 hours. Symptoms include: severe tremors, hyperthermia, agitation, and running fits.
☠️ If seizures, paralysis, or coma occur, prognosis is poor. Pets with more mild symptoms may improve after weeks of treatment but are likely to continue to suffer some degree of neurological symptoms.
