## Root Cause

Rodenticides, especially anticoagulants like brodifacoum, cause secondary poisoning when a pet ingests a poisoned rodent, leading to internal bleeding and death within 24-72 hours.

## Workarounds

1. **If ingestion is within 2 hours, administer activated charcoal (1-2 g/kg orally) and immediately transport to vet for blood clotting time test (PT/PTT).** (70% success)

2. **For confirmed anticoagulant poisoning, start vitamin K1 therapy: 5 mg/kg SC initially, then 2.5 mg/kg PO every 12 hours for 3-4 weeks, with weekly PT monitoring.** (85% success)

## Dead Ends

- **Induce vomiting immediately after ingestion** — Vomiting is ineffective for anticoagulant rodenticides as they absorb quickly; also risks aspiration if pet is already bleeding internally. (85% fail)
- **Give vitamin K1 only once** — Anticoagulant rodenticides require repeated vitamin K1 therapy for 3-4 weeks; a single dose is insufficient and bleeding resumes. (90% fail)
- **Use activated charcoal for all rodenticide types** — Activated charcoal is only effective within 1-2 hours of ingestion and does not neutralize absorbed toxins; also contraindicated for some bait formulations. (70% fail)
