How to recognize oxalate plants indoors

Most oxalate houseplants are aroids with a spadix + spathe bloom structure (e.g., Philodendron hederaceum, Epipremnum aureum, Dieffenbachia seguine, Spathiphyllum wallisii). Leaves are typically cordate to lanceolate, often with variegation or speckling.

Typical symptoms in pets

  • Immediate oral/lingual irritation and drooling.
  • Pawing at the mouth, decreased appetite, occasional vomiting.
  • Eye irritation if sap contacts eyes.

Prevention & placement

Keep out of reach (hanging planters, high shelves), train pets away, and wipe sap if pruning. Consider swapping to pet-safer species in accessible areas.
