Yes, chrysanthemums are toxic to cats. Chewing the blooms or leaves causes drooling, vomiting and diarrhea, and the plant can irritate skin.

Also known as: Mums, Garden Mums, Daisy Mum, florist chrysanthemum · Chrysanthemum morifolium

What makes it toxic

Pyrethrins and sesquiterpene lactones concentrated in the flower heads. Pyrethrins affect the nervous system of insects and mildly irritate the gut and skin of pets.

Warning signs to watch for

Drooling, vomiting, diarrhea and loss of coordination in larger ingestions, plus itchy red skin where the fur brushed the plant. Signs appear within hours.

What to do if your cat eats it

Remove plant material, rinse any skin contact areas and offer water. Call your vet if vomiting repeats or the cat seems uncoordinated; most small ingestions stay mild.

Common questions

Are the flowers more toxic than the leaves?

Yes, pyrethrins concentrate in the flower heads, and potted fall mums put plenty of blooms at muzzle height. Keep the whole plant off-limits anyway.

My indoor cat ate a mum from a bouquet — how worried should I be?

Expect a day of drooling and possible vomiting. Call your vet if signs escalate or if any other unknown flowers were in the arrangement.
