Is Rubber Plant Toxic to Cats?
Also known as: Rubber Tree, Rubber Fig, Indian Rubber Bush · Ficus elastica
What makes it toxic
A milky latex sap containing ficin, a proteolytic enzyme that irritates the tissue of the mouth, tongue and skin. It is not a true systemic poison; effects are local and self-limiting.
Warning signs to watch for
Drooling, pawing at the mouth, lip or tongue redness, vomiting and loss of appetite within a short time of chewing. Skin or eye contact with the sap can cause redness and itching.
What to do if your cat eats it
Rinse the mouth with water, wipe sap off the fur or skin and offer fresh water. Call your vet if drooling and vomiting last more than a few hours, or if the eye was splashed with sap.
Common questions
Is the rubber plant the same as a rubber tree?
Yes — rubber plant, rubber tree and rubber fig all refer to Ficus elastica, and all carry the same irritating sap.
Can a cat die from chewing a rubber plant?
Fatalities are not documented. The worst cases involve heavy drooling, vomiting and mouth pain, which resolve with basic care.
Is the rubber plant safe if I cut it back?
Pruning actually increases risk, because the cut stems ooze the most sap. Keep the cat away until the cuts dry over.
