Common questions
Are daisies toxic to cats?
Yes — the ASPCA lists daisies as toxic to cats.
What happens if a cat eats daisies?
The ASPCA publishes this as the clinical signs, word for word: “Vomiting, diarrhea, hypersalivation, incoordination, dermatitis” It names the toxic principle as “Sesquiterpene, lactones, pyrethrins and other potential irritants”. We reprint their wording rather than paraphrasing it — a paraphrase is what gets quoted back with the caution removed. It does not tell you how much is too much, and neither do we: the ASPCA publishes no threshold for any of these plants.
Are daisies safe for cats?
Not according to the ASPCA, which lists daisies as toxic to cats and publishes clinical signs for it. That is the answer to the question as asked; we are not going to soften it, and we are not going to tell you a small amount is fine either — the ASPCA publishes no threshold for any of these plants.
