🔴 HIGH — Dangerous
Why is it risky?
Most common rat poisons use anticoagulant compounds (e.g. brodifacoum) that block vitamin K-dependent clotting factors, causing internal bleeding. Cats can be exposed directly or secondarily by eating a poisoned rodent.
Affected Systems
Digestive · Cardiovascular · Respiratory
Symptoms
Lethargy, pale gums, bruising, bleeding from nose/gums, labored breathing, blood in urine/stool, weakness. Onset can be delayed 2–5 days after exposure.
What To Do
Veterinary emergency. Vitamin K1 treatment is effective if started promptly, even before symptoms appear.
Notes
Secondary poisoning (eating a poisoned mouse) is a real and often-overlooked risk pathway.
