Monstera deliciosa

AI-assisted guide by the Eaoae editorial team · Last updated 2026-10-05 · Based on independent veterinary sources

Monstera deliciosa is one of the most popular indoor plants due to its striking fenestrated leaves, but it is not pet-safe. The key takeaway is that while it looks harmless, it contains compounds that can cause significant oral irritation and digestive upset if ingested by your furry or feathered friends.

🚫 Keep away from

Cats — Ingestion of calcium oxalate crystals causes immediate mouth and throat irritation, leading to drooling and vomiting.
Dogs — Chewing on the leaves releases needle-like calcium oxalate crystals that irritate the mucous membranes of the mouth and esophagus.
Birds — Birds are particularly sensitive to the calcium oxalates found in the plant, which can cause severe swelling of the airway and difficulty breathing.
Rabbits — The sharp calcium oxalate crystals can cause painful oral ulcers and gastrointestinal distress in these small herbivores.
Guinea Pigs — Like rabbits, guinea pigs suffer from oral irritation and potential digestive blockages if they nibble on the toxic foliage.
Reptiles — While less common, reptiles that ingest the plant may experience internal irritation and digestive issues due to the calcium oxalate content.

👀 Signs to watch for

Excessive drooling or foaming at the mouth
Vomiting or retching
Difficulty swallowing or chewing
Redness or swelling of the lips, tongue, and throat
Diarrhea or loss of appetite
