Is Signet marigold toxic to cats?

Tagetes tenuifolia

Mildly toxic to cats

Mildly. The ASPCA lists signet marigold as mildly toxic to cats — a chewing cat typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. The ASPCA lists Tagetes species as mildly toxic to dogs and cats due to thiophene compounds in the foliage. Despite the edibility of signet marigold flowers for humans, pets may experience mild gastrointestinal upset if they ingest the plant. Contact dermatitis is possible in sensitive individuals.

What to do if your cat ate signet marigold

  1. Remove any plant material from your cat's mouth and move signet marigold out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of signet marigold to the appointment so it can be treated correctly.
