Short answer: yes. Monstera deliciosa is toxic to cats, dogs, and horses according to the ASPCA. If you have curious pets, keep your monstera out of reach — or swap it for one of the pet-safe alternatives below.
Why is monstera toxic to pets?
Monsteras contain insoluble calcium oxalate crystals. When a pet chews the leaves, these microscopic needle-like crystals embed in the mouth, tongue, and throat, causing:
- Oral pain and pawing at the mouth
- Excessive drooling
- Vomiting
- Difficulty swallowing
It's rarely fatal, but it's painful and frightening — for you and your pet. The same crystals make philodendron, pothos, and peace lilies toxic too.
What to do if your pet chews monstera
- Remove any remaining plant material from their mouth.
- Offer water or a small amount of milk/yogurt — it can help soothe the irritation.
- Call your vet. Most cases resolve with supportive care, but a vet should assess the severity.
- For emergencies, the ASPCA Poison Control hotline is (888) 426-4435 (a consultation fee may apply).
