What Happens If a Pet Eats Rat Poison?

The AVMA is unequivocal: all rodenticides are potentially toxic to any mammal, and any suspected ingestion requires immediate emergency care. Contact your veterinarian, an emergency veterinary clinic, or the ASPCA Animal Poison Control Center at 888-426-4435. The Northern New England Poison Center (1-800-222-1222) serves NH and is available 24/7, though its primary focus is human poisoning — it can sometimes help with animal questions, but your veterinarian or ASPCA are the dedicated resources for pets. Call even if your pet looks completely normal.

Rodenticides fall into a few general categories that act in different ways at a high level: anticoagulant products affect the blood's ability to clot, while other categories, such as bromethalin and cholecalciferol, work through entirely different mechanisms. The AVMA stresses that the brand name alone is often not enough — bring the product's name, active ingredient, and EPA registration number from the label so the veterinary team can respond appropriately.

Several rodenticide categories cause delayed signs that may not appear for hours or even days after exposure, so a pet that seems fine right after eating bait can still be in real danger. Waiting for visible symptoms — bleeding or bruising, weakness, tremors, difficulty breathing — costs time that matters for treatment. Call before symptoms appear, not after.

Do not induce vomiting or give any home remedy unless a veterinarian or poison-control expert explicitly instructs you to. Some exposures make vomiting dangerous, and inducing it without guidance can do more harm than good — this decision needs to be made by a professional who knows the specific product involved.
