Why
Monstera deliciosa is closely related to philodendron and contains the same insoluble calcium oxalate crystals.
Its large leaves are tempting for some pets to chew, but most stop quickly because of the pain.
How to recognize it
Very large glossy leaves develop splits and holes as the plant matures, and thick aerial roots grow from the stems. Young plants have solid heart-shaped leaves and are easily mistaken for philodendron.
Signs to watch for
- Drooling
- Pawing at the mouth
- Vomiting
- Difficulty swallowing
What to do
- Rinse the mouth and offer water.
- Contact a vet if symptoms continue or if your pet has trouble breathing.
- Place large monsteras where curious pets cannot chew the leaves, or add a physical barrier.
