- Scent deterrents: Citrus peels (replace every few days), pet-safe repellents, or aromatic herbs like rosemary/lavender nearby.
- Housekeeping: Clean fallen leaves/flowers promptly; use organic fertilizers/pesticides only.
- Records: Keep plant names/photos on hand for fast ID in emergencies.
🚑 What To Do If Exposure Happens
- Stay calm, assess quickly: what plant, how much, when; take a photo/sample.
- Check symptoms: vomiting, drooling, breathing, seizures, consciousness.
- Call your vet or an emergency clinic immediately.

Never induce vomiting unless a vet explicitly instructs you to do so.
