⚠ Caution

Iris

Iris spp.

Iris (Iris spp.) is a widely cultivated ornamental plant that is mildly to moderately toxic to cats. The rhizomes (underground stems/bulbs) contain the highest concentration of toxic compounds, including irisin, iridoid glycosides, and pentacyclic terpenoids. The leaves and petals carry lower but non-trivial amounts of these irritants.

Important Notes

Toxic compounds: irisin (resinous glycoside), iridoid glycosides, pentacyclic terpenoids; rhizomes most concentrated

Mechanism: irisin and iridoid compounds cause direct GI irritation; skin contact with sap may cause dermatitis

Symptoms: drooling, vomiting, diarrhea, lethargy, abdominal pain; skin or eye contact with sap may cause redness or irritation

Rhizomes are the most hazardous part — risk increases during planting or dividing bulbs

Symptoms are usually mild with leaf nibbling; contact your vet if rhizome ingestion is suspected
