My cat ate monstera thai constellation — FAQ
Is monstera thai constellation poisonous to cats?
Yes — the ASPCA lists Monstera Thai Constellation (Monstera deliciosa 'Thai Constellation') as mildly toxic to cats. As a cultivar of Monstera deliciosa, it carries the same toxicity the ASPCA lists for the species ("Swiss Cheese Plant", Monstera deliciosa): toxic to dogs and toxic to cats. The toxic principle is insoluble calcium oxalate crystals, released when the plant is bitten or chewed. Signs include oral irritation; intense burning of the mouth, tongue and lips; excessive drooling; vomiting; and difficulty swallowing. Serious cases are rare but keep it and any cuttings out of reach of pets, and contact your vet if ingestion is suspected.
