Why
Pothos is one of the most common houseplants. Like philodendron and dieffenbachia, it contains insoluble calcium oxalate crystals that irritate the mouth and throat when chewed.
Its trailing vines are tempting for cats to bat at and chew. Most pets stop after the first bite because of the discomfort.
How to recognize it
A trailing or climbing vine with glossy heart-shaped leaves, often marbled with yellow, white or silver, usually grown in hanging baskets or along shelves. It is easily confused with heartleaf philodendron, which causes similar mouth irritation.
Signs to watch for
- Pawing at the mouth
- Drooling
- Vomiting
- Difficulty swallowing
What to do
- Rinse the mouth with water and offer a cool drink.
- Contact your vet if drooling or vomiting continues, or immediately if breathing is affected.
- Hang pothos high and trim trailing vines so cats cannot reach them.
