Toxic CompoundsSesquiterpene; Lactones; Pyrethrins; Other potential irritants

First Aid & Prevention

First 30 Minutes

• Remove any remaining plant material from the exposed animal's mouth or skin immediately
• Rinse skin contact areas with mild soap and cool water for 10 to 15 minutes to reduce irritation
• Do not induce vomiting or give home remedies unless explicitly directed by a veterinarian

Contact Vet Immediately

• Your cat or dog has ingested any quantity of the plant
• Symptoms including vomiting, diarrhea, incoordination or skin rash appear after exposure
• The exposed animal is a young, elderly or immunocompromised pet

Prevention

• Keep daisy/chrysanthemum plants and cut arrangements out of reach of cats and dogs
• Wear disposable gloves when handling the plants to avoid potential skin irritation
• Avoid planting daisies in areas accessible to unsupervised pets or grazing animals

Treatment & Prognosis

• Veterinarians may administer activated charcoal to reduce toxin absorption for recent ingestions
• Symptomatic care includes antiemetics for vomiting, fluid therapy, and antihistamines for dermatitis
• Monitor neurological symptoms like incoordination and provide supportive care as required

Target Organs

Gastrointestinal tractSkinNervous system

Mechanism of Action

• Irritant compounds including pyrethrins and sesquiterpene lactones irritate mucosal membranes, skin, and nervous system tissues upon exposure

Other Species Risk (CliniTox)

Information from CliniTox veterinary text.

Small mammals (rabbits, guinea pigs, hamsters): May experience similar gastrointestinal irritation and dermatitis as cats and dogs if exposed to the plant

Birds: Toxicity not formally studied, ingestion of large quantities may lead to digestive distress and general weakness

Confusion Risk

The following plants look similar and may be confused:

Marguerite Daisy Argyranthemum frutescens

Visually similar with matching daisy-like flower heads; key difference is its finer, feathery foliage compared to broader Chrysanthemum leaves

Gerbera Daisy Gerbera jamesonii

Has large, vibrant daisy-like flowers; key difference is that Gerbera daisies are confirmed non-toxic to cats, dogs and horses per ASPCA data
