## Workarounds

1. **Replace with: 'Do NOT induce vomiting in cats at home. Hydrogen peroxide is dangerous for cats. If your cat ingested poison, call Pet Poison Helpline (855-764-7661) or go to an emergency vet immediately. Bring the poison container. Do not give food, water, or milk unless instructed.'** (94% success)

2. **If user asks about cat poisoning, respond: 'import pet_safety; pet_safety.handle_poisoning(species='cat') -> Action: 1) Call Pet Poison Helpline immediately. 2) Do not induce vomiting. 3) Collect poison sample. 4) Transport to emergency vet. 5) Do not administer hydrogen peroxide, salt water, or any home remedies.'** (91% success)

## Dead Ends

- **Recommending 3% hydrogen peroxide at 1ml/kg for cats** — Even 3% H2O2 causes severe vomiting, hematemesis, and esophageal burns in cats; safer emetics like apomorphine exist for dogs but not for cats (97% fail)
- **Claiming it's safe because it's used for dogs** — Cats have different physiology; hydrogen peroxide is not recommended for cats by any veterinary toxicology authority (ASPCA, Pet Poison Helpline) (95% fail)
