Is Pothos toxic to cats and dogs?
Quick answer
Pothos is toxic to cats and dogs. Pothos (Epipremnum aureum) contains calcium oxalate raphides (needle-like crystals of calcium oxalate monohydrate) in all plant tissues — leaves, stems, roots, and aerial roots. When chewed by pets, these raphides pierce the oral mucosa, tongue, lips, and inner cheeks, causing immediate oral irritation, intense burning, hypersalivation, and difficulty swallowing (dysphagia). The mechanism is mechanical rather than neurotoxic, but the pain response can cause significant distress. Ingestion of large quantities can cause esophageal ulceration and rare cases of upper airway swelling in cats.
Start here:
- 1. Immediately relocate Pothos to an area completely inaccessible to pets — high shelves, enclosed plant cabinets, or rooms with closed doors
- 2. If pet has chewed Pothos, rinse mouth with water to remove plant residue and offer water to drink

What to do about toxic to cats and dogs and Pothos
- 1
Immediately relocate Pothos to an area completely inaccessible to pets — high shelves, enclosed plant cabinets, or rooms with closed doors
- 2
If pet has chewed Pothos, rinse mouth with water to remove plant residue and offer water to drink
- 3
Monitor for signs of oral irritation: pawing at mouth, excessive drooling, vocalization, or refusal to eat
- 4
Contact veterinarian if oral swelling, persistent drooling, or difficulty breathing develops
- 5
Consider replacing Pothos with verified non-toxic alternatives: spider plant, Peperomia, or Calathea
Keeping pets safer around Pothos
Do not purchase Pothos for any household with cats or dogs that exhibit chewing behavior. If already owned, place in hanging planters or high shelves completely inaccessible to pets — the plant should be at least 4 feet above floor level with no furniture nearby that could provide access.
