Satin Pothos
Scindapsus pictus
Also known as: Silver Leaf Philodendron, Silk Pothos
Satin Pothos (Scindapsus pictus), sometimes sold as Silver Leaf Philodendron or Silk Pothos, is a trailing houseplant with soft green leaves marked by silver patches. It is not safe for cats, especially if they chew the leaves or stems. The main risk comes from insoluble calcium oxalate crystals, also called raphides. These are tiny, needle-like crystals stored inside the plant tissue. When a cat bites the plant, the crystals can scratch and irritate the mouth, tongue, and throat. The sap may also contain enzymes that make the burning and swelling feel worse. Most cats stop after a bite because the pain starts quickly, but symptoms can still be dramatic: drooling, pawing at the mouth, swollen lips or tongue, vomiting, or trouble swallowing. Keep satin pothos and similar trailing vines out of reach. If your cat chews the plant, rinse the mouth gently with water if you can do so safely, and contact a veterinarian if swelling, vomiting, or breathing trouble appears.
Important Notes
Main hazard: Insoluble calcium oxalate raphides in the leaves and stems cause immediate mouth and throat irritation when chewed.
Symptoms: Sudden oral pain, heavy drooling, pawing at the mouth, swollen lips or tongue, vomiting, and difficulty swallowing.
Why cats get exposed: The trailing vines and silver-patterned leaves can be easy for curious cats to reach or bat at.
Action: Move the plant out of reach, offer water or gently rinse the mouth if safe, and call a vet if swelling, breathing trouble, or repeated vomiting occurs.
