Italian Arum

Arum spp.

Italian Arum (Arum italicum) is a tuberous ornamental plant toxic to cats throughout all its parts. It belongs to the Araceae family and contains insoluble calcium oxalate crystals (raphides) along with aroin — a toxic protein compound — and saponins. The bright orange-red berries are especially hazardous as they are visually attractive and contain the highest concentration of toxins.

Important Notes

Toxic compounds: insoluble calcium oxalate raphides, aroin (toxic protein), saponins; berries most concentrated

Mechanism: raphides cause immediate mechanical irritation to the oral and GI mucosa; aroin and saponins add systemic toxicity

Symptoms: intense oral burning, drooling, pawing at mouth, vomiting, diarrhea; severe berry ingestion may cause systemic illness

The attractive orange-red berries pose the greatest risk, particularly to inquisitive cats

Seek veterinary care if berry ingestion is suspected or if GI symptoms are severe
