What plants are toxic to cats?
Of the 13 plants covered here, the ASPCA Animal Poison Control Center lists 10 as toxic to cats and 2 as non-toxic; for 1 it publishes no entry at all. That is not the whole of its database — it names over a thousand species, and these are the ones people actually ask about. Each page quotes its entry rather than summarizing it.
Toxic to cats, on the ASPCA’s list
Each one has its own page, with the clinical signs the ASPCA publishes, word for word.
Non-toxic to cats, on the ASPCA’s list
That is their classification, not a promise from us: a cat that eats any plant can still vomit or choke on it.
Plants the ASPCA does not name at all
Neither list carries an entry under this name. We publish that gap instead of turning dozens of species pages into a verdict it never gave.
