Satin Pothos

Symptoms reported in cats

Most serious first.

1. 1
   Dyspnea and swelling of the upper airways Rapidly following exposure (as tissue swelling develops) · This is a rarer but serious complication that occurs if the localized inflammation and swelling (edema) in the throat become severe enough to block the air passages.
2. 2
   Excitability, nervous spasms, convulsions, and occasional encephalitis Not explicitly specified in the sources · While plants containing insoluble oxalates typically only cause localized oral irritation, these specific, severe neurological signs have been reported specifically in cats after ingesting Philodendron species.
3. 3
   Renal failure Not explicitly specified in the sources · Although insoluble calcium oxalates are generally known as gastrointestinal irritants that do not cause systemic organ damage, the Merck Veterinary Manual explicitly notes that renal failure has been reported in cats following the ingestion of Philodendron.
4. 4
   Oral irritation, burning pain, pawing at the mouth, swelling of the tongue and pharynx Immediate (upon chewing or ingestion) · This is a direct physical reaction caused by sharp, needle-like insoluble calcium oxalate crystals penetrating the delicate mucous membranes of the mouth.
5. 5
   Excessive salivation (drooling) Immediate · Drooling is triggered by the intense burning and irritation in the mouth; you may also notice the cat frantically pawing at its face due to the discomfort.
6. 6
   Vomiting, retching, and lack of appetite (decreased appetite) Shortly after ingestion · The cat's refusal to eat is largely due to the severe oral discomfort, while vomiting and retching are caused by the crystals physically irritating the gastrointestinal tract if swallowed.

Important notes

Satin Pothos (Scindapsus pictus) is a popular trailing houseplant with distinctive silver markings on its leaves. It is toxic to cats and should be kept out of their reach, as chewing on the leaves or stems can cause immediate and significant discomfort. The plant's tissues are filled with tiny, sharp, needle-like crystals called insoluble calcium oxalates. When a cat bites into the plant, these crystals embed themselves in the soft tissues of the mouth, tongue, and throat, causing intense irritation and a burning sensation. This physical injury is the primary cause of the plant's toxicity. Symptoms appear right away and include intense drooling, pawing at the mouth, visible swelling of the lips or tongue, and vomiting. In severe cases, swelling can obstruct the airway, making breathing difficult. If you suspect your cat has chewed on a Satin Pothos, contact your veterinarian for guidance.

• 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.
