Why is it dangerous to pets?
Chrysanthemums, mums and many daisies contain pyrethrins and sesquiterpene lactones. Pyrethrins affect nerve sodium channels — the same target as permethrin flea treatments that are so dangerous to cats.
Most exposures cause only gut upset and skin irritation, but cats are more sensitive and larger amounts can cause tremors.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of chrysanthemum poisoning
- Drooling, vomiting, diarrhoea
- Skin redness, itching or rash on the muzzle and paws
- Wobbliness, unsteady walk
- Tremors or twitching in larger ingestions
- Lethargy and loss of appetite
What to do right now
- Call your vet or a poison line with the amount and the pet weight.
- Wash the skin with mild soap and water if plant sap is on the fur.
- Keep cats away from cut flowers — they are far more sensitive to pyrethrins.
- Watch for tremors and go in if they appear.
