My understanding is that peace lilies are toxic in large quantities due to oxalate crystals. What that threshold is, i’m not sure. This post was a few hours ago, how is your rabbit doing?
I found this info online about symptoms:
“If your rabbit accidentally ingests this plant, it may cause oral irritation, usually with difficulty swallowing and irritation of the tongue, lips, and mouth. That is because this plant has toxicity called insoluble calcium oxalate crystals. Some reports stated that it is similar to other house plants belonging to the Araceae family.
Peace lilies release these oxalate crystals when animals bite or chew this plant. This results in tissue penetration and irritation of the gastrointestinal tract causing diarrhea in rabbits. A rare scenario is also seen, such as the swelling of an animal’s upper airway, making it difficult for them to breathe.”
