Is Rubber Plant Toxic to Cats?
Ficus elastica
!Irritant
The milky sap irritates skin and mouth. Most cats leave it alone; the danger is the leaves they chew.
Ficus elastica produces a milky latex sap that irritates skin and mucous membranes. Chewing a leaf causes drooling, vomiting and mouth discomfort; sap on the coat causes a rash.
It is a large, glossy statement houseplant, and lower leaves at cat height are the ones that get chewed.
Which parts are dangerous
- sap
- leaves
- stems
What to watch for in the UK
- Very common large houseplant, often inherited with a flat.
- Sap stains fabric and is sticky — and transfers to fur.
- Trimmed stems leak sap onto floors.
- Wipe sap up and wash hands.
If your cat has already chewed it
- Wipe the mouth and coat with a damp cloth.
- Phone your vet if drooling persists or skin is broken.
- Watch for vomiting.
Signs that need a vet
- drooling
- vomiting
- mouth irritation
- skin rash
Take a photo of the plant, and a cutting if you can do it safely — identification is half of the vet's decision. Out of hours, use your practice's emergency number. This page explains risk; it cannot diagnose your cat and it contains no home treatments.
If your cat has vomited after eating a plant, see the cat vomiting guide and, if there is blood, vomiting blood. For a general red-flag checklist, use sick cat symptoms. If the worry is food rather than a plant, the can cats eat guide covers 36 everyday foods.
