Safety status
What this means for your cat
Cats grazing on coreopsis (also called tickseed) aren't ingesting anything toxic — ASPCA classifies it as non-toxic to cats and identifies no toxic principle, so a quick mouthful from a cut-flower bouquet is a non-event.

Questions about Coreopsis
Is coreopsis toxic to cats?
Coreopsis is considered non-toxic to cats. It is classified as generally safe, and no toxic compounds have been documented for this plant.
What happens if my cat eats coreopsis?
Consuming small amounts is unlikely to cause any reaction. If your cat eats a large quantity of the fibrous plant material, mild vomiting or diarrhea is possible due to the bulk of plant matter, not any toxic principle.
How much coreopsis would make a cat sick?
No toxic dose exists for coreopsis because the plant is non-toxic. Any GI upset would be from the sheer volume of fibrous material eaten, not a poisonous compound — small nibbles pose no concern.
Should I call my vet if my cat ate coreopsis?
A call is not urgent for small ingestions, but if your cat consumed a significant amount and is vomiting repeatedly or seems distressed, contact your veterinarian for guidance.
