Dahlia
Dahlia pinnata
Dahlia (Dahlia spp.) is a common garden flowering plant that is mildly toxic to cats. The plant contains irritant compounds primarily in the leaves and stem. These substances cause gastrointestinal irritation and, with skin contact, mild dermatitis.
Important Notes
Toxic compounds: sesquiterpene lactones and unidentified irritant components
Mechanism: direct mucosal and GI irritation
Symptoms: vomiting, diarrhea, mild drooling; skin contact may cause localised redness or itching
All above-ground parts carry some irritant potential; flower petals are least concentrated
Symptoms are usually mild and self-limiting, but contact your vet if your cat ingests a large quantity
