We all love to keep plants in and around the house, but we should consider which ones are safe for pets. Young or new pets tend to nibble and taste plants as they explore and become familiar with their environment, but some garden and house plants are toxic.
Symptoms may range from a mild upset stomach to a severe toxic response that can lead to death. It is important to know which plants are safe, as even common plants can be deadly.
Identifying Toxic Plants
Plant toxicities can be organized into four classes:
- Major Toxicity: May result in serious illness or death if ingested.
- Minor Toxicity: May result in vomiting or diarrhea if ingested.
- Oxalates: Contain juice or sap with oxalate crystals that can irritate the skin, mouth and/or throat, cause swelling, difficulty breathing, pain, and/or an upset stomach
- Dermatitis: Contact with thorns or sap may result in a skin rash.
If you suspect a poison–related emergency, contact your local veterinarian or the ASPCA Animal Poison Control Center at 888–426–4435.
