What is Rodent Bait?
Rodent bait (anticoagulants) is severely toxic to cats and dogs. Bleeding can be delayed for days — call a vet immediately, do not wait for symptoms.
Also known as: anticoagulant, rodenticide, bromadiolone, brodifacoum, diphacinone, warfarin, mouse poison, rat poison.
Symptoms to Watch For
🐕 In Dogs
- Lethargy, weakness, and pale gums (signs of internal bleeding)
- Bleeding gums, nosebleeds, or bruising under the skin
- Blood in stool (dark or red) or urine
- Difficulty breathing if bleeding into the lungs or chest
🐈 In Cats
- Lethargy, weakness, and pale gums from blood loss
- Bleeding gums, nosebleeds, or bruising
- Dark or bloody stool
- Difficulty breathing from internal bleeding
What to Do If Ingested
- Call a veterinarian or poison hotline immediately, even if no symptoms yet — bleeding is often delayed 2–5 days.
- Find the bait package and note the active ingredient (e.g. brodifacoum, bromadiolone, diphacinone).
- Estimate how much was eaten and when.
- Do not wait for bleeding to appear; early decontamination and vitamin K1 work best.
Steps apply to both cats and dogs. When in doubt, call a vet or poison hotline before acting.
When to Call the Vet Immediately
Call your veterinarian or a poison control hotline right away if you notice any of these:
- Any rodent bait was eaten
- Pale gums, weakness, or unexplained bruising
- Bleeding from the nose, gums, or in stool/urine
- Coughing or difficulty breathing
Frequently Asked Questions
Frequently Asked Questions
How long after eating rodent bait do symptoms appear?
Anticoagulant rodenticides block vitamin K, which the body needs to clot blood, but symptoms are usually delayed 2 to 5 days while clotting factors run out. By the time you see bleeding, the poison has been acting for days. Call a vet the day it is eaten, not when symptoms start.
What is the treatment for rodent bait poisoning?
If caught early, a vet may induce vomiting and give activated charcoal, then start vitamin K1 for several weeks (long-acting baits like brodifacoum and bromadiolone require extended treatment). In severe cases with active bleeding, plasma transfusions and hospital care are needed.
Are "pet-safe" rodent baits actually safe?
No rodent bait is truly safe for pets. Products may be marketed as safer, but bromethalin (a brain toxin) and cholecalciferol (vitamin D3) baits have no easy antidote and are just as dangerous. Store all baits where pets cannot reach them, and call a vet with the active ingredient if any is eaten.
